This is a bit of a panic post!
I have disconnected our rainwater collection system with the aim of improving it. We have purchased a 500L tank to store run off from the roof. Under the old system it was pumped up from 2 small tanks housed above the electric pump. The main water tank is on top of the hill above the house - let's say 5m in vertical height. The house water is gravity fed from the main tank.
My problem is that the pump is not working when I tested it. The electric motor is on, but no water is being pumped. The model is called Riva Flo TF30. It is possible that it needs priming (how?) or thet I have damaged it by running it with no water in the system.
Any suggestions on how to remedy this would be gratefully received.
