I have a Stuart Turner Monsoon Universal 4 bar twin negative head which feeds the house.
We had a bathroom installed in the loft. After a while the pump began hunting in the middle. Turning on for about 5 seconds and the turning off whilst there was not running water, apparent leaks or overflowing cisterns. The hunting then began to get closer and closer together (timewise).
We had the pump exchanged with a brand new one by Stuart Turner installations guy. For a few hours the hunting ceased but that evening it started again. It also seems to be becoming more frequent again.
At night the pump has to be switched off because the noise is so loud it is enough to wake everyone in the house and deeply upset our neighbours. The situation is so stressful as it is bad enough bothering oursleves but it also causing our neighbours distress and any help would be grately grately appreciated.
In summary as mentioned before, the pump is brand new so non return valves are obviously not the problem (neither is the pump). There are no dripping taps or overflowing cisterns. There are no apparent leaks in the pipework to the loft.
Please help!
Many thanks in advance!
ps I am going to try closing the outlet isolating valves tonight, but because the pump is brand new I doubt this is the problem and will confirm that water is being drawn. Is there any way of finding out where it is being drawn from if this is the case? (assuming no visible leaks or dripping taps / showers / loos etc)
