Hi
My water pump started playing up. That is, the flow was irregular and, as I have a Rinnai instant water heater, that meant taking a shower was either dodging the over-hot water or dodging the freezing cold water!
Tonight, I removed the pump, took it apart, cleaned it up and re-installed it. But now it won't turn off! I recognise that there is a bit of an air-lock going on and I've had all taps open to try to release it. But that hasn't worked.
I also think I understand that it will switch off when the back pressure is sufficient - have I got that right?
But, I've left it running for a good 5 minutes or so, to allow the pressure to build up and it still doesn't turn off.
Do I need to leave it running for longer or is my pump ready for the scrap heap? A new pump is only about £50 and I'm happy to pay that, but what if I have the same problem with the new one?
Can anyone advise please?
Cheers, Adam
