The Platon Aqua Pump is a ready to use complete water control system principally designed for use in below ground structures to control water ingress.
The system consists of a pre-formed polyethylene sump basin, a mains powered 230v submersible pump, a non-return valve assembly and a battery operated high water level alarm, which is linked to an integral float switch.
IMPORTANT NOTE: The Platon Aqua Pump must only be used for pumping ground water.
When installing Cavity Drainage Membranes careful attention must be given to provide a suitable drainage solution. Natural drainage is not normally possible or convenient in below ground situations, so mechanical drainage must be used.
The Platon Aqua Pump System can be linked to the Aqua Channel Drainage System to manage water ingress from retaining walls and in turn pumping out to a suitable drainage point.
The pump should not be used to pump grey water from; sinks, washing machines, dishwashers, condensing boilers or effluent.
We will not accept responsibility or liability for pump failure or damage caused due to the misuse of the pumping system.
The Sump Basin is a polyethylene pre-formed chamber, measuring 560mm high x 540mm diameter (top) x 460mm diameter (base) and is most commonly located into the floor, finishing flush with the surrounding floor level.
The Sump Basin is supplied with a structural foam flat lid, which can accept foot traffic.
The lid can be easily removed to allow regular maintenance of the internal submersible pump or pumps.
The pump is positioned within the Sump Basin and is controlled by an automatic snap-action float switch.
As the water level increases within the sump the float rises and when the pre-set switch level is reached the pump will automatically operate and discharge the water. The Pump is 230v and requires wiring into an independent fused spur outlet within 1.5m of the pump.
To avoid any discharged water backing-up into the sump basin, a non-return valve assembly is provided. This is fitted directly to the submersible pump outlet via flexible couplings and supplied ready to accept a standard 1½” waste pipe.
The High Water Level Alarm is an essential component within the Aqua Pump system. In the event of mechanical failure of the pump or an unexpected power failure, the water will continue to fill the sump. When the water reaches the level of the alarm float switch, the 80db alarm will sound, giving warning of the failure.
The alarm is powered by a 9v battery, which should be positioned in a convenient location such as a kitchen / lounge where it will be easily heard. Once the alarm is heard immediate action must be taken to avoid flooding.
The site conditions or situation being encountered may well determine the positioning of the Platon Aqua Pump System. However, ideally it should be sighted at the lowest point of the room and or closest to the nearest point where water will be discharged.
The most important thing is to make sure that water can get to the pumping station. Once the pump position has been established, dig a circular hole to a depth of 650mm and to a width of 650mm.
At the base of the walls of the sump basin, drill 4 holes opposite each other, (12mm dia), insert two lengths of reinforcing bar (660mm long) through drilled holes .These will add additional anchoring for the sump basin in the ground.
Fit the high water level alarm float switch sensor into the pre-cut hole provided within the wall of the sump basin and ensure that the (jaw) of the switch sensor is open and hangs downwards. Bring the two cables with bullet connectors attached back into the sump basin either through one of the holes provide or by drilling a hole and leave ready to be connected to the wires of the water alarm.
NB: If the water discharge pipe from the pump is to be concealed below the floor, then a 1½” hole will need to be cut through the side of the basin. However, the position of this hole can only be determined once the sump basin has been offered into position, otherwise the discharge pipe can be taken through the lid of the basin.
Lay approx 100mm concrete at the base of the hole and insert the sump basin.
Using a spirit level, adjust the top of the basin to the level of the finished floor level. Fill the basin two thirds with water, then infill around sump basin with concrete, ensuring it is well compacted.
NB: If a Cavity Drain Membrane is being installed over the floor, then the concrete will need to be finished 100mm lower than the top of the sump, drill a number of perforations to the edge of the sump basin and infill void above concrete with 20mm stone.
However, if a Cavity Drain Membrane is not going to be installed over the floor, the concrete should finish flush with top of the sump basin.
Insert the Aqua Pump in the base of the sump basin and connect the water discharge pipe to the flexible coupling already attached to the pump. The discharge end of the pipe can be taken through a wall and extended to a gully outlet at ground/street level.
Alternatively, the discharge pipe can be connected straight into a soil pipe using a ‘boss’ connection.
Connect the wires from the float switch sensor to the wires of the water alarm using the bullet connectors provided. Then connect the pumps' power cable into a fused spur outlet (fuse rating 5amp) and test the pump and alarm for working order.
It is recommended that the Platon Aqua Pump System is maintained or serviced at a minimum every six months. This should be carried out by a competent contractor (under a maintenance contract) or by the property owner.
During a service all parts of the Aqua Pump kit should be checked to ensure fully operational. The sump should be cleared of any silt / sludge that may have accumulated to avoid potential damage to the pumps.
The sump must be filled with water to ensure the automatic float switch and pump are fully operational. We recommend renewal of the 9v battery within the alarm and that the alarm float switch checked to ensure the alarm sounds. Any defective parts must be replaced / repaired to avoid failure of the system.
Example of suitable sump, pump and drainage schedule can be found in the Platon Installation Manual.
We recommend records of each service be kept by the property owner.
