Platinum AquaSump ECO - Basement Sump Station

Health & Safety Considerations

Work from a safe, well-lit platform and cordon off the area to control dust and trip hazards. Wear cut-resistant gloves, eye protection, hearing protection when coring or cutting concrete, and a FFP-rated mask suitable for fine dust.

Before you excavate or drill, survey the floor and walls with a detector and, where necessary, open up locally to confirm there are no buried services, damp-proof courses or structural bearings in the line of the sump or discharge pipe.

Electrical work must comply with BS 7671; supply the pump from a suitably protected 230V circuit with 30mA RCD additional protection and an accessible means of isolation (for example a switched fused connection unit).

In dwellings, sockets are generally required to be RCD-protected, with limited exceptions, so plan for RCD protection as standard.

Site Preparation

Confirm that a sump station is acceptable under the project’s waterproofing design. In cavity-drain systems, situate the chamber at the low point of the slab so perimeter channels can fall to it and keep access clear for periodic inspection and servicing (a key expectation of BS 8102-type designs).

Choose a location that allows a straightforward rising discharge in 32mm pressure pipe to a lawful outfall and where the highest point of the discharge can be set above the local flood level (typically street level) to prevent backflow. Plan penetrations through walls so they avoid structural reinforcement and are sealed against water ingress on both sides.

Ensure there is a dry, level base for the chamber and a route for a dedicated power spur and any alarm cabling.

Limitations And Good Practice

This kit is intended for groundwater control in basements and cellars; it is not suitable for sewage, food waste or aggressive chemicals.

The pump is an automatic KSB AmaDrainer 301 submersible with integral float control; it requires free movement of the float and a clear sump free from debris. The included non-return (swing check) valve must be installed in the correct orientation and the discharge should be 32mm internal diameter pressure pipe (as supplied).

Keep the discharge as short and as straight as possible, use swept bends rather than tight elbows, and include an isolation valve (recommended) above the union to simplify future maintenance.

Provide a high-level alarm and battery back-up if the risk assessment or client brief calls for continued protection during power outages. Where the discharge connects to a drainage system or to a gully, obtain approval from the sewerage undertaker or local authority and arrange the connection so that any back-pressure cannot return to the chamber.

The KSB guidance requires the highest point of the discharge to be above flood level to prevent backflow; observe this carefully.  

Step-By-Step Installation

1. Mark Out And Excavate The Sump Recess: Set out a circular recess to accept the 55cm diameter HDPE chamber and excavate to a depth that will allow the 60cm tall chamber to sit with its lid level to the final floor finish. Prepare a flat, rigid base; a 100mm concrete pad is typical in domestic work. Compact and level the base so the chamber cannot rock.
   
   

2. Position And Orient The Chamber: Place the chamber on the base with the intended discharge exit facing the planned wall penetration. Check there is space on top for the inspection lid and for removal of the pump in future. If your waterproofing is a cavity-drain system, bring the perimeter channels to the chamber and form inlets using compatible grommets and seals to maintain system integrity.
   
   

3. Core The Discharge Penetration: Mark a suitable high point through the wall for the 32mm discharge. Core drill the wall to suit your chosen sleeve (commonly 50–63mm) so the 32mm pipe can pass with an annular space for sealing. Ensure the route allows a steady rise to the outside, avoids services and allows the final highest point to be above flood level or street level. Deburr and install a sleeve, sealing both sides to prevent water tracking.
   
   

4. Fit The Tank Connector To The Chamber: Using the supplied 1¼” tank connector and a hole-saw sized to the connector, drill through the chamber wall at the marked outlet position. De-burr, fit the tank connector with its sealing washers, and tighten evenly to form a watertight connection. Thread the 32mm solvent-weld adaptor to the connector.
   
   

5. Assemble The Internal Discharge Line: Cut the supplied 32mm PN16 PVC pressure pipe to suit. From the pump outlet, install the plain union connection, then the EDPM swing check (non-return) valve in the correct flow direction, followed by a short riser and a 90° elbow into the tank connector. Keep joints square, dry-fit to confirm lengths, then solvent-weld each joint in accordance with the adhesive manufacturer’s instructions. Where specified by your method statement, install an isolation valve above the union to aid maintenance.
   
   

6. Place And Connect The Pump: Lower the KSB AmaDrainer 301 automatic pump into the chamber, ensuring the foot sits level and the float switch moves freely. Connect the discharge union to the pump’s G1¼” threaded outlet and tighten. Dress the pump cable up the chamber wall without strain or tight bends and arrange it so it cannot interfere with the float.
   
   

7. Build The Rising Main To Outside: Run 32mm pressure pipe from the tank connector to the wall penetration and out to the termination point, maintaining a continuous rise with swept bends. Clip the pipe at regular intervals to prevent movement. Externally, complete the run to the approved outfall and arrange the termination to avoid splashing and icing. Insulate or trace-heat where frost is a concern. Ensure the highest point of the line lies above the flood level to resist backflow, as required by KSB installation guidance.
   
   

8. Seal Penetrations And Make Good: Seal around the discharge pipe where it passes through the wall sleeve with a flexible waterproof sealant or mechanical seal, and make good internally and externally so the path is watertight and tidy. Where the chamber sits within a cavity-drain floor, reinstate the floor build-up around the rim while maintaining clear access to the lid.
   
   

9. Electrical Connection And Alarm: Provide a dedicated 230V supply via a switched fused connection unit (typically fused at 3–5A per pump nameplate), with 30mA RCD protection and a local isolator. Do not use extension leads or multi-way adaptors in basements. If fitting a high-level alarm or battery back-up, install and commission in accordance with the manufacturer’s instructions and your waterproofing design.
   
   

10. Commissioning: Part-fill the chamber with clean water until the pump’s float operates. Observe the automatic operation through at least three cycles to confirm reliable start and stop, correct non-return valve operation, and dry joints. Check the external termination for secure, splash-free discharge. Record the installation details, power supply readings and discharge route for the O&M manual.

Handover And Everyday Use

Explain to the occupier that the system operates automatically and should be left energised at all times.

Show the location of the electrical isolator and any alarm. Advise that the lid must remain accessible, that the chamber should not be covered by fixed joinery or heavy items, and that no solids, sand, paint wash-out or cleaning chemicals should be allowed into the drainage channels or the chamber.

Confirm the discharge route and the need to keep the external outlet clear of snow, leaves and debris.

Maintenance And Aftercare

Set up a service interval appropriate to the risk and usage. As a minimum, visually inspect quarterly to ensure the lid is accessible, the external termination is clear and the alarm (if fitted) proves on test.

At least annually, isolate the supply, remove the lid, lift the pump clear using the cable or a lifting cord as recommended, and hose down any silt or bio-film from the chamber and pump casing. Check the non-return valve for debris and correct operation, verify all unions and solvent-welds for integrity, and confirm the float has free movement.

Re-commission by filling the chamber with clean water and observing multiple start/stop cycles. Maintain a log of service dates and findings. Designers of maintainable basement waterproofing systems expect reliable access for this routine; keep the area clear.

Troubleshooting

If the pump hums but does not discharge, check for a tripped RCD or blown fuse, confirm the float is free, and inspect the non-return valve for a jammed flap.

If the pump short-cycles rapidly, look for trapped air or a stuck float and ensure the water level range is adequate.

If water returns to the chamber after the pump stops, verify non-return valve orientation and seating and raise the high point of the discharge if it is below flood level.

Persistent alarms usually indicate blocked channels or a fouled impeller; isolate, remove and clean the pump as above.

Other Information

The KSB installation guidance for the AmaDrainer series specifies a G1¼ discharge port and recommends a 32mm internal diameter discharge line.

It also requires the highest point of the discharge to be above the flood level to prevent backflow from the sewer. Electrical supplies should be RCD-protected in domestic settings, and sockets or spurs serving the pump should comply with BS 7671.

If you are unsure about any electrical aspect, engage a qualified electrician under Part P of the Building Regulations.

Where the discharge connects to a drain or gully, the outfall must be lawful; seek consent from the sewerage undertaker or local authority where required.

Q) What is the Platinum AquaSump ECO Basement Sump Station and how does it control basement groundwater?

A) The Platinum AquaSump ECO Basement Sump Station is a ready to assemble HDPE chamber and pump set that automatically removes groundwater and seepage from basements and cellars. The cylindrical chamber measures about 60cm×55cm and provides roughly 110L gross capacity, giving a buffer for intermittent inflows from cavity drain membranes, perimeter channels and general infiltration. At its core is a KSB AmaDrainer 301 automatic submersible pump with integral float switch, which starts and stops without user input as water levels rise and fall. Supplied fittings include a non return valve, a 90° elbow, a plain union, a 1¼in tank connector, a 32mm solvent weld adaptor and 32mm PN16 PVC pressure pipe for the discharge. Once assembled, the system delivers quiet, low energy dewatering with dependable performance up to about 6.5m head and around 166L/min at favourable duty points. A Clarke Drain HDPE frame and lid finish the installation neatly at floor level for easy inspection and service.

Q) When should the Platinum AquaSump ECO Basement Sump Station be specified in a waterproofing scheme?

A) Choose the Platinum AquaSump ECO Basement Sump Station where a below ground space requires reliable removal of groundwater and seepage rather than foul waste. It suits Type C cavity drain systems under BS 8102 where perimeter channels or membrane studs direct water to a sump for controlled discharge. Typical use cases include new and retrofit basements, cellars, plant recesses, inspection pits and lift pockets where intermittent inflows must be managed quietly and automatically. The compact chamber fits most plant zones and its smooth HDPE interior aids cleaning during planned maintenance. The included 32mm pressure pipework lets installers create a robust rising main with standard tools, while the non return valve prevents backflow when the pump stops. Where resilience is required for critical rooms, add an isolation valve, a high level alarm and either a standby power source or a secondary pump, following the project risk assessment and client brief.

Q) What flow and head can the Platinum AquaSump ECO Basement Sump Station achieve in practice?

A) The Platinum AquaSump ECO Basement Sump Station uses a KSB AmaDrainer 301 that is designed for clean and slightly dirty water in domestic basements. Typical characteristics include a maximum head of about 6.5m and a peak flow in the region of 166L/min, with actual duty governed by installation geometry, static lift, friction losses and the duty point on the pump curve. The pump has a G1¼ outlet, IP68 motor protection, solids handling up to about 10mm, a maximum immersion depth near 2m and a maximum liquid temperature around 50°C. The supplied EDPM sealed swing check valve, 90° elbow and short internal riser are arranged to minimise losses and keep the footprint compact. For best performance maintain a neat rising discharge in 32mm pressure pipe with swept changes in direction, avoid unnecessary fittings and keep the highest point above local flood level to resist backflow from external drainage.

Q) What exactly is included with the Platinum AquaSump ECO Basement Sump Station kit?

A) Each Platinum AquaSump ECO Basement Sump Station kit contains a rotationally moulded HDPE chamber about 60cm tall and 55cm diameter, a Clarke Drain HDPE frame and lid, and a factory matched KSB AmaDrainer 301 automatic submersible pump with integral float control. The hydraulic pack includes a non return swing check valve, a 90° elbow, a plain union for quick pump removal, a 1¼in tank connector for the chamber wall penetration, a 32mm solvent weld adaptor and a length of 32mm PN16 PVC pressure pipe for the discharge. Installers cut and solvent weld the line to suit the route and clip it at regular centres. The arrangement is intended for straightforward site assembly with common tools, allowing a tidy headworks that prevents backflow, limits water hammer and simplifies future servicing. Optional items such as an isolation valve, high level alarm or standby power are not included as standard but are recommended where risk and client brief require resilience.

Q) How is the Platinum AquaSump ECO Basement Sump Station installed and what skills are needed?

A) Installation is within reach of competent contractors familiar with below ground waterproofing and pressure pipework. Set a level base, often a small concrete pad, and position the chamber so perimeter channels can fall to it. Drill the chamber wall for the supplied 1¼in tank connector, fit the connector with its seals and thread in the 32mm solvent weld adaptor. Assemble the internal discharge from the pump outlet to the tank connector using the plain union, the EDPM swing check valve, a short riser and the 90° elbow, dry fit to confirm lengths then solvent weld each joint following the adhesive manufacturer’s instructions. Core the wall for the 32mm rising main, sleeve the penetration, and run a continuous rise to a lawful outfall using swept bends. Seal all penetrations against water tracking. Provide a 230V supply with 30mA RCD protection and local isolation in line with BS 7671. Commission by wet testing several automatic start and stop cycles.

Q) Where should the Platinum AquaSump ECO Basement Sump Station be located in a basement layout?

A) Place the Platinum AquaSump ECO Basement Sump Station at the hydraulic low point so gravity brings inflows to the chamber without ponding. In Type C designs this is generally where perimeter channels converge. Leave clear access above the lid for inspection, wet testing and pump removal, and avoid positioning beneath fixed joinery or immovable equipment. Choose a route for the 32mm rising main that avoids structural reinforcement, services and damp proof courses, and allows the highest point to be set above local flood level, often street level, to resist backflow. Minimise horizontal runs and tight changes in direction to reduce friction losses and improve duty. Where possible keep the external termination sheltered and free draining and plan for frost protection if the line passes through cold zones. A simple access drawing for the O&M manual helps occupants and service engineers locate isolators, alarms and the discharge route.

Q) What electrical requirements apply to the Platinum AquaSump ECO Basement Sump Station?

A) The pump within the Platinum AquaSump ECO Basement Sump Station is typically a 230V single phase unit with a motor output around 0.18–0.25kW depending on variant, sealed to IP68 for submersible duty. Electrical work must comply with BS 7671. Provide a dedicated supply via a switched fused connection unit, usually fused at 3–5A to suit the pump nameplate, with 30mA RCD additional protection and a local isolator that remains accessible above any risk level. Avoid extension leads and multi way adaptors in basements. Where an alarm or battery back up is specified, run separate circuits or spurs as recommended by the alarm manufacturer and protect cables from damage and damp. Keep joints and connections off the floor and route the pump cable so it cannot interfere with the float switch. Record circuit details, protective device ratings and test readings in the commissioning sheet for the building’s operation and maintenance record.

Q) How quiet and energy efficient is the Platinum AquaSump ECO Basement Sump Station in day to day use?

A) The Platinum AquaSump ECO Basement Sump Station is designed for quiet, efficient operation in occupied homes and light commercial spaces. The AmaDrainer 301 is a compact submersible that runs only when the integral float rises, so energy consumption is limited to actual pumping periods and idle power is negligible. The submersible configuration, smooth internal hydraulics and short headworks keep airborne noise low and structure borne vibration to a minimum. A non return valve immediately above the pump controls water hammer and limits return flow that could otherwise cause odour or re wetting. For best acoustic results place the chamber on a rigid, level base, clip the rising main securely at sensible centres, and avoid tight elbows that increase turbulence. With correct siting, users typically hear only a brief, soft pumping sound during operation, and the float controlled duty helps regulate humidity without frequent cycling.

Q) What routine maintenance does the Platinum AquaSump ECO Basement Sump Station require?

A) Set a maintenance plan aligned to the risk profile of the space. At minimum, carry out a quarterly visual check that the lid is accessible, alarms prove if fitted, and the external termination is free of debris. Annually, isolate the electrical supply, lift the lid, remove the pump by the cable or a lifting cord as recommended, and hose down silt and biofilm from the chamber and pump casing. Inspect the EDPM swing check valve for debris and correct seating, confirm the plain union and solvent welded joints remain sound, and ensure the float switch moves freely without fouling. Refill the chamber with clean water and observe several automatic cycles to verify start, run and stop behaviour and to inspect for leaks. Maintain a log of service visits, findings and corrective actions. Keeping perimeter channels clean and clear greatly reduces silt loading and extends pump and valve life between services.

Q) What are the common troubleshooting steps for the Platinum AquaSump ECO Basement Sump Station?

A) If the pump hums but no water discharges, first confirm the supply, isolator and RCD are on and healthy, then check that the float rises freely and that the non return valve is not jammed. If the pump short cycles, look for trapped air at the impeller or a float that is catching on the cable or chamber wall, and verify that the inflow is not a rapid dribble that triggers the float repeatedly. If water returns to the chamber after the pump stops, confirm the non return valve orientation and condition and check that the highest point of the discharge is above local flood level so external pressure cannot drive water back. A persistent high level alarm usually indicates a blocked channel, a fouled impeller or a failed supply. Isolate safely, remove and clean the pump, re test operation with clean water, and if issues persist consult a qualified engineer for diagnosis.

Q) What liquids can the Platinum AquaSump ECO Basement Sump Station handle and what should be avoided?

A) The Platinum AquaSump ECO Basement Sump Station is intended for clean and slightly dirty water typical of groundwater and seepage collected by cavity drain membranes and channels. The AmaDrainer 301 can pass solids up to about 10mm and liquids up to roughly 50°C, making it suitable for general basement dewatering. It is not designed for sewage, food waste, oils, fuels, solvents, strong chemicals or abrasive slurries. Avoid paint washings, sand and construction debris which can clog channels and shorten pump life. Keep the chamber free from objects that might obstruct the float action. If the project involves grey water or other non compliant fluids, specify a correctly rated lifting station and obtain approval for the discharge. As with any pumping solution, a pre filter on channels, good housekeeping and periodic inspection are the best protection against unwanted debris reaching the impeller or check valve.

Q) How does the Platinum AquaSump ECO Basement Sump Station integrate with Type C cavity drain membrane systems?

A) In a Type C system under BS 8102, studs on the membrane face create a drained cavity that guides moisture to perimeter channels which fall to a sump. The Platinum AquaSump ECO Basement Sump Station provides that collection and discharge point. Position the chamber at the low point and form membrane terminations and channel entries using the manufacturer’s grommets and seals so the system remains drained yet vapour tight. The smooth HDPE chamber aids periodic cleaning and visual inspection through the Clarke Drain lid. The pump’s automatic float control manages inflow without manual intervention, and the included non return valve prevents re wetting of the cavity after each duty. Designers often add a high level alarm for early warning and may add a secondary pump or standby power where consequences of flooding are severe. Clear access to the lid and pipework is a core expectation of a maintainable Type C design.

Q) What discharge pipework and fittings should be used with the Platinum AquaSump ECO Basement Sump Station?

A) The kit is matched to a 32mm PN16 PVC pressure line that is solvent welded for leak tightness and durability. From the pump outlet use the plain union for quick removal, then the EDPM sealed swing check valve, a short riser and a 90° elbow into the 1¼in tank connector on the chamber wall. From there, run a continuous rise to the lawful outfall using swept bends wherever possible and clip at regular centres. Keep the system simple, short and free of unnecessary restrictions to reduce friction losses and preserve duty. Sleeve and seal all penetrations to prevent water tracking. KSB guidance calls for the highest point of the discharge to be above local flood level to resist backflow. Threaded fittings are typically rated around 12bar, but joints should be made sensibly without overtightening. Where maintenance access is important, fit an isolation valve above the union so the pump can be removed without draining the rising main.

Q) What are the key technical specifications of the Platinum AquaSump ECO Basement Sump Station?

A) The chamber is rotationally moulded HDPE, approximately 60cm high and 55cm diameter, with a gross volume near 110L. The lid and frame are Clarke Drain HDPE for a neat, load tolerant floor finish. The KSB AmaDrainer 301 pump provides a G1¼ discharge, IP68 motor protection, solids handling up to about 10mm, maximum liquid temperature around 50°C, maximum immersion depth near 2m, and typical performance up to about 6.5m head and around 166L/min depending on the duty point. Supplied fittings include a plain union, an EDPM swing check valve, a 90° elbow, a 1¼in tank connector, a 32mm solvent weld adaptor and 32mm PN16 PVC pressure pipe. Internal pipework and fittings align with EN1452 2 and 3, ISO161 1, BS21, DIN2999 and ISO7. The system is intended for clean and slightly dirty water in basements and cellars and is not suitable for foul waste or aggressive chemicals.

Q) How should the outfall for the Platinum AquaSump ECO Basement Sump Station be arranged?

A) The outfall must be lawful and capable of receiving pumped clean water without causing nuisance. Many projects discharge to a suitable gully, a dedicated storm line or a soakaway where appropriate and permitted. Always obtain approval from the sewerage undertaker or local authority if a sewer connection is proposed, and ensure the discharge path cannot return back pressure to the sump. Arrange the highest point of the line above local flood level so backflow cannot siphon into the chamber during surcharging events. Provide a free draining termination that avoids splashing or icing and consider insulation or trace heating where external runs pass through cold zones. Keep the outlet clear of leaves and debris and avoid positions where snow drifts could block the grille. Document the route, valves and termination in the O&M manual and include a simple diagram so occupants and service engineers can check the outlet easily.

Q) What options exist to improve resilience of the Platinum AquaSump ECO Basement Sump Station against power cuts?

A) The Platinum AquaSump ECO Basement Sump Station runs from a 230V supply and will not pump during a power interruption. For critical rooms consider resilience measures. A high level alarm provides early warning and prompts manual intervention. A battery backed alarm extends protection when mains power fails. For continued pumping, specify a suitably sized UPS or a generator that can deliver the starting current and run load of the AmaDrainer 301, and ensure fuel or battery capacity covers the expected outage duration. Some designs add a secondary pump with an independent supply path for redundancy. Good housekeeping also helps by keeping channels clear so stored volume in the chamber and channel network can buffer short outages. Record all resilience provisions in the O&M manual and instruct the occupier on testing regimes, especially for alarms, so the system is not caught unprepared during peak rainfall events.

Q) How does the Platinum AquaSump ECO Basement Sump Station support easy servicing over its life?

A) Serviceability is built in. The plain union above the pump allows quick disconnection without cutting the rising main and the EDPM swing check valve sits close to the pump for easy inspection. The Clarke Drain lid provides ready access for wet testing, debris removal and visual checks of the float and cable dressing. The chamber’s smooth HDPE surface resists scaling and cleans quickly with a hose. The 32mm pressure pipework is solvent welded for long term integrity and is clipped to prevent strain on joints. During installation, leaving a clear zone above the lid and recording the discharge route, isolator positions and alarm details greatly simplifies future visits. A simple annual routine of cleaning the chamber, checking the non return valve and proving automatic cycles with clean water is normally sufficient, and many homeowners adopt a quarterly visual check of the outlet and lid to catch issues early.

Q) What are the main limitations and good practice notes for the Platinum AquaSump ECO Basement Sump Station?

A) This kit is for groundwater and seepage, not foul waste or aggressive chemicals. The AmaDrainer 301 requires free movement of its float so the chamber must not contain loose items that could obstruct it. The included check valve must be fitted in the correct orientation and the discharge should use 32mm pressure pipe throughout to maintain performance. Keep the rising main as short and straight as possible and use swept bends rather than tight elbows. Sleeve and seal penetrations to prevent water tracking. Provide an isolation valve above the union where maintenance access is important. Set the highest point of the discharge above local flood level and obtain consent for any sewer connection. Electrical work must comply with BS 7671 with 30mA RCD additional protection and local isolation. A high level alarm and resilience planning are recommended where the consequence of flooding is significant for finishes and contents.

Q) How is the Platinum AquaSump ECO Basement Sump Station commissioned after installation?

A) Commissioning begins with a dry inspection of mechanical and electrical work. Confirm the chamber is level, pipework is clipped and joints are sound, the check valve orientation is correct, the union is tight, the float moves freely and the cable is dressed clear of the float path. Verify the supply polarity, protective device ratings and RCD operation. Part fill the chamber with clean water until the float triggers pump start, then observe the discharge for a smooth, splash free outfall. Allow the level to fall until the float stops the pump and check for backflow through the non return valve. Repeat at least three cycles, listening for unusual noises and watching for joint weeping. Record measured voltages, currents if available, RCD trip times, discharge route and termination details for the O&M manual. Finally, brief the occupier on the system, its alarms, isolator location and routine maintenance.

Q) What are the health and safety considerations when installing the Platinum AquaSump ECO Basement Sump Station?

A) Prepare a safe working area with good lighting and clear routes, and cordon off drilling zones to control dust and debris. Wear eye protection, a suitable FFP rated mask, hearing protection when coring, cut resistant gloves and sturdy footwear. Survey floors and walls with a detector, and where doubt exists open up locally to avoid cutting reinforcement, damp proof courses or hidden services. Use a core drill with a working clutch and an assistant for dust extraction where practicable. Handle solvents for the 32mm weld joints in accordance with the adhesive manufacturer’s guidance and provide ventilation while bonding. Electrical work must comply with BS 7671 and use 30mA RCD additional protection, with a switched fused connection unit and local isolation. Lift the pump by its cable or a lifting cord as recommended, not by the float. Keep the chamber area tidy so the float cannot snag on offcuts, packaging or tools.

Q) How should occupants use and look after a Platinum AquaSump ECO Basement Sump Station day to day?

A) The Platinum AquaSump ECO Basement Sump Station is automatic and should remain energised at all times. Occupants should keep the lid accessible, avoid placing heavy items across it and never introduce sand, paint washings, solvents or cleaning chemicals into channels or the chamber. If the system has a high level alarm, test it periodically as advised by the installer. During cold weather check that the external termination remains clear of ice and debris. After building works or deep cleaning, ask the installer or a competent service provider to remove any silt that may have entered the channels. If unusual noise or odour is noticed, contact a service engineer promptly to prevent minor issues becoming significant faults. The O&M manual should be kept with the property documents and include a simple drawing that shows the location of the sump, the isolator, any alarms and the discharge route.

Q) How does the Platinum AquaSump ECO Basement Sump Station compare with fabricating a bespoke sump on site?

A) The Platinum AquaSump ECO Basement Sump Station accelerates programme time because the components are matched and ready to assemble with common tools. The HDPE chamber is robust, chemical resistant and smooth inside, unlike ad hoc chambers that can be rough, porous or hard to seal. The matched AmaDrainer 301 pump has a proven duty envelope for domestic basements, and the supplied union, check valve, elbow and 32mm PN16 PVC pressure pipe provide a compact, low loss headworks that is easy to service. Installers drill one chamber penetration for the 1¼in tank connector and solvent weld the rising main, which is simpler than fabricating multiple penetrations or casting pipe sockets. A Clarke Drain HDPE lid gives a clean inspection point at floor level. The result is a standardised installation that is easier to maintain, document and support, and that aligns well with the maintainability expectations of BS 8102 designers.
