My diaphragm water pump SUK-0227 has started playing up.
Initially it would run for several seconds after taps were switched off. 20 or 30 seconds on occasion.
It then worked normally for a few days with no recurrence of the fault.
It now runs but delivers no water. The diaphragm pump is clearly operating judging by its own sound. I can also hear noises at the tap similar to when initially priming the system after a drain down, ie "gurggling" noises as if it is trying to pump.
I have checked that the hot water drain valve is closed, that there are no visible leaks anywhere, that the pump casing screws are all tight (as per a previous post), and that there is plenty of water in the tank. Does anyone have any knowledge that might help?
I have done a search on the site and, although there are threads referring to other problems, I can't find anything similar.
Thank you in anticiipation!
