Now as it's a pressure system which should cut out once the required pressure is achieved I could only assume there was a leak somewhere. Consequently I am now having to switch the pump off and on at the main control panel to avoid constant noise from the pump and wearing out the pump / switch. DC to AC Inverters Pure Sinewave Power Inverter Waeco Modified Sinewave Inverters Horns Compact Electric Horns Electric Trumpet Horns All Electrical Surge dampers became necessary in some caravans, because the storage water heaters like the Carver and Truma models all needed to have a small air cap in the tanks. This was to allow the water to expand when it was heated. The consequence of ths compressed air cap was that the hot water system attained a higher pressure than the cold water, and when a mixer-tap was opened ( for example in the shower) the pressure in the hot tank would push hot water out before the pressure switch on the cold would turn on. This gave alternate surges of hot and warm water rather than a steady temperature.

If there’s no water leakage preventing the water system from pressurising properly, the prime suspect for the ‘surging’ must be the Whale Pressure Switch. So if the problem does not spontaneously cure itself, beginning by swapping the Pressure Switch would make sense. And, if there are no leaks and fitting a replacement Pressure Switch and pump is ineffective, that would just leave the Whale surge damper.

Thanks Derek. Have saved a copy of that exploded view for future reference. Suspect this might not be the last issue I have with the pressure switch.

The Whale damper is quite ‘cheap and cheerful’ (though not exactly cheap) with no pressure adjustment. As mentioned in this 2013 Caravantallk thread Fishfinders Humminbird Lowrance Garmin Fishfinders Garmin Transducers Navigation AIS Receivers Transponders

I can only assume that something else happened when the surge damper was fitted, perhaps a pipe was rerouted that prevented it from vibrating against a wooden panel, or something like that. 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 had another go and I've discounted a leak at the tap as it stops dripping after 30 secs or so. 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. My immediate thought was that I must have a leak somewhere caused by a frozen pipe over the winter. But I took particular care to drain the system of water using a Floe draindown attachment and also driving the vehicle around with the drain valves open for a while to release any dregs of fluid.

Historically, some submersible water pumps were notoriously reluctant to prime and, when initially submerged, needed to be shaken to expel air and allow the pump’s impeller to 'get a grip’ on the water. OK if an Aquaroll-type external water container was being used, but not if the pump was in a motorhome’s fresh-water tank. Reich advertise “a patented ventilation system which is integrated into many of our pumps and provides immediate output after immersing into the tank”, and your Reisch pump should have that feature ad not suffer from priming problems.
