Hi
6 months ago we had out main hot water tank moved to a ground floor location and a new salamander negative head pressure pump (ESP 120 CPV) installed to pump hot water to the whole house.
This has been excellent until Friday when it gurgled a bit and stopped working. It has a red light on option 2 stating it has water starvation/ aeration. I thought this might just be a glitch so turned the pump off and back on. The pump then turns on and goes through its test procedure and during that time the water flows really well. However after a minute the pump just turns off and when we turn the hot tap on it does not activate.
I have subsequently today uncoupled the pump and checked all the pipes for an air lock and then put the pump back and this has had no affect. I assume now that there must be an air lock in the pump itself?
Any thoughts would be welcome before my wife sends me out to live with the dog.
