Hi all, just thought I'd report back now that I've fixed the problem with the intermittent running of the water pump. Like Nick Andrew above, the fault was the NRV in the water filter housing which was leaking, hence the sloshing noise I could when the pump switched on and off. This was no...

Hi all - I had a chat with Truma technical department today. In their opinion, the fault is likely to be a non-return valve inside the ultraflow filter housing fitted to the side of the van where the pump plugs in. It appears the NRV is integral to the filter housing and cannot be adjusted or...

Hi Hutch - the surge damper is described as an accessory in our Truma manual and is something we don't have fitted. Our system just has a Truma Ultraflow Smart Pressure Switch which appears non- adjustable.

I fixed the leak on the external shower connector. The two 'O' rings looked dry so I smeared some vegetable oil on them and now there is no leak. I don't think we have a surge damper, just a pressure switch. The Truma handbook does show this device but I can't see it in the pipework.

It's a Truma Ultraflow smart switch which, as far as cam see, is non-adjustable i. e. There doesn't appear to be any external adjustment.

Hi guys - the day got off to a bad start when the pump failed this morning. I've now changed the pump, pressure switch and non-return valve but to no avail. We still have the original problem of the pump turning on and off. I've also checked for leaks and there are none that I can see. The...

Otherclive - yes, you're right, sounds a lot like my problem. I'm wondering if the sloshing noise I can hear when the pump switches on and off is water moving backwards and forwards in the pipework, i. e. the NRV isn't working properly . Also, I've re-checked the connections outside the van and...

Thanks, I'll check that out.

Hi Prof, thanks for your reply. I'll do some more investigation, using your suggestions, and get back to you.

Hi there, I'm new to this forumso here goes. We have a water pump oscillating problem with our 2015 Coachman VIP 520/4 that we've never seen before during the six years we've owned the caravan until now. The problem started this week when we arrived on site and I connected up the water system...
