Water pump replacement 2015 Aspect 30J
Replaced burnt out Shureflo fresh water pump and working fine now except when i turn on tap at the washroom sink. The pump, rather than run steady while the tap is on, it surges.... off, on, off, on, off, on.......all the time the tap is open. Kitchen tap, shower, toilet and outside shower all run smoothly. There is also a distinct noise, like the ratteling of pipes, in the area of the hot water tank (sorry, no tank... hot water on demand)..... The hot water works fine at the sink and the shower and outside shower as well. I have scanned the plumbing diagrams for my coach (2015 Aspect 30J) and come away none the wiser...... also there is no diagram for the plumbing of "on demand" hot water plumbing. Any suggestions what I should be looking for/at?
