Mains water not working

Hi Dan.
I have a 2009 Jayco Outback Sterling and have also had some water problems which I think may be related to the under van water pressure regulator.
It may be that you have the same issue although my water does come back on after a time of using the water via the pump which of course is coming directly from the tanks.
I am still trying to solve the issue and in your case I suggest the first thing you do is to check the little water direction indicator on your water pipes under the van.
The arrows should run horizontal with the van .
If this does not solve the issue then I am guessing the regulator is the culprit.
Sorry I cannot be any more helpful as I also go through the process of finding the remedy to a similar problem.

Most likely your pressure reduction vlave.

There is also a non return valve in the line as well somewhere which could also affect it.

I guess the only solution is to talk to a plumber or see if you can pull the non return and pressure reduction valve out ad have a look.

Check that a wasp hasn't built a nest in the end where you plug your hose into the van pipe - one did on mine & stopped water ....... have to break up the clay mud with a thin screwdiver

Yes Dan.
After using the pump for say a shower I turn it off then check the mains again.
More often than not the water flow returns but it is NEVER at a high pressure so this tends to make me think that it is the pressure regulator.
I recently had a mate who is a water technician (does water reticulation for wineries/orchards etc and who is pretty handy with his van handy work) and he reckons the regulator is faulty.
His suggestion was to take it out completely and replace it with more pipe. He sayspark pressures are never high enough to damage any thing within the van.
Hope you come up with a remedy soon.

Hi Dan. I had the same problem recently when camped at Curlwaa. The water is supplied from the park's own pumps so there is not much pressure. I removed my pressure reducing valve, undid the inlet side and removed the little plastic valve and spring. There is also a gauze strainer in the that had a bit of rubbish in it but my main problem was not enough pressure to open the spring tension. You have reminded me now, I haven't put the valve back together. Cheers,Bob

Have you run your tap at the front of the van?

Sometimes there is an air bubble in the line and the tap can get it out.

Some Jaycos use a Filtamate FM-12-350 Pressure Limiting Valve just behind the water inlet. The two "O" rings in it, mainly the lower one, stretch and need to be replaced.
