Hi guys, I'd appreciate any help on this.
I have a large rainwater harvesting tank sunken in my back garden (wife dug the 2m square hole whilst I carried the soil through the house) - the tank works perfectly; the submerged pump on the other hand periodically goes faulty and I've had to replace the unit in the past (its a Hydroforce (HydroForce Clean Water Submersable Water Pump - https://www.hydroforcepumps.co.uk). My current pump has also gone faulty and I'm trying to diagnose and fix it rather than spend £290 for a replacement). Its a float pump which operates when water pressure in the inlet hose drops.
The pump is wired to an internal 13A plug socket and an indoor control unit controls when the pump is switched on (to pump water to a 15m high roof water tank, a tank which feeds the toilets). Recently the pump has tripped the plug socket ring; to resolve this, I've taken the front cover off the pump and found the earth to be somewhat corroded - I've cleaned the earth connection, coated the earth connection in Vaseline, and the pump can be connected to the mains without tripping the house plug circuit.
However, the pump no longer pumps water either when connected back into series with the internal control unit, or when independently plugged into a wall socket.
I am now reaching the extent of my fault finding skills, and whilst I do have a meter, I have no idea as what I should measure to try a diagnose the problem.
Could anyone help? Thanks
