However, as Adria has chosen to fit the pesky Whale Pressure Switch that has its own NRV, there should be no imperative need for another NRV at or near the pump.

Even when there’s a NRV attached to a subersible pump’s outlet, that NRV will be ‘downstream' of the pump itself and, when the water system is drained down, the fresh-water tank is empty and thereand there might be residual water trapped ‘downstream’ of the NRV, the submersible pump should still self-drain.

I've just taken the connector apart and looked at the hose and cable inside and it looks perfectly fine with no sign of water damage to the interior and no sign of hose deterioration. I did notice that the hose is an interference fit on a spigot and that there was a 'rim' of some form of colourless dried adhesive around the hose end where it abuts the connector. Needless to say that adhesive has gone now as I disturbed it, but there was no sign of a leak past it. Also when I run the pump there's no air coming out of the taps (at least not yet) which I would have expected with any sort of leak in the pipes.

The solution is to provide a similar air cap for the cold water. This would act in a similar way to the hot, and smoothed or damps out the surges.Pumps Accumulator Tanks Pressure Pumps General Purpose Pumps Electric Bilge Pumps Electric Bilge Pump Switches Manual Bilge Pumps Manual Galley Pumps Pump Spares & Accessories More Pumps It is also apparent the pump takes a long time to turn off after the tap has been closed, which Audiorob rightly points to the pressure switch adjustment needing attention. I've just had another go and I've discounted a leak at the tap as it stops dripping after 30 secs or so.
