If the water flow stops and the pump continues to run for more than about a 10 seconds, the motor can begin to heat up which can distort the plastic surrounding it and the shaft seals. Ultimately water can enter the motor housing, and that will adversely affect the motor, causing it to draw more current, and prematurely fail.

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.

Confused. Could there be anything else I should ask the user? I had initially suggested switch pump off at caravan door each use, but later said perhaps leave on as that could affect something. 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.

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. Installation instructions for the damper are here

I'll take a more detailed look when I get home and maybe swap it out with the new pump. If that resolves the problem then I'll see if it's possible to disassemble it and fix it and it can become my spare pump. Does anyone have any other suggestions of likely cause or steps I could follow to diagnose the problem more accurately. 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.
