Water pump pulsating

Theres a little pressure adjusting screw on the front of some of the surflow pumps sometimes under a sticker,see if yours has one ant try adjusting it, count the turns either way in case you need to return it to its present position.

Ours makes a bit of racket when the tap is just on at a trickle, not so bad if the tap is running at a 'proper' rate. I would suggest you stand outside and listen to it. Ours is just audible at a distance of about 2 metres which is about the minimum distance you are likely to be from another van.

It is a necessary operation in a van and I don't think people get too concerned about it as it is likely to only run for a minute or so at a time, noisy neighbours ( we were next to a Spanish couple on an Aire this year and they sang as they did everything ), barking dogs, children and generators are more likely to annoy people.

I have read that some people mount the pump on a piece of rubber to try and insulate it from resonating the board it is fitted to. But this is unusual and the jury has not ruled on its effectiveness.
