Starcraft Mains water inlet non-return valve on 17.58.3

[halbster]

Does anyone know where I would find the non-return valve on the mains water inlet? Or what it looks like or what to look for? Was running on tank water using the pump on the weekend, but it started to pump the water out through the mains inlet, so assume there is a non return valve in there that is not "valving".

Could be anywhere depending on the day the van was built @halbster
Ours is in the same cupboard area as the pump and hot water system from memory.

The non return valve is part of the plastic inlet itself.

There is a small Spring loaded valve that can get stuck open.

You can sometimes poke something like a scewer in, or alternately you can disconnect from inside and then a 1/4 turn and it can come out to replace.

Our O ring wouldn't stay on the valve inside and leaked. Did away with it and bought a brass one and relocated the fitting, got sick of finding the keys to open the door/flap.

My bad.....
Just re-read the original post and @Bellbirdweb is correct.... The non-return valve I was thinking about stops mains water from getting to the pump

 

[halbster]

Great thanks guys, I'll take a closer look at the inlet for the issue.

Worse thing is you need to buy the whole box and dice. They don't sell the fitting alone.

I bought the fitting by itself at the local Jayco dealer. Picked up a spare just encase.

I have had trouble with water pressure in the van when hooked up to mains and I have now hooked the water up to the front tap. I took the tap washer out first and now the pressure is excellent. Has anybody tried this . the mains inlet on the van on the side seems to block up very easily so I tried the front tap. Regs stan

Tried it at home to see if it worked just in case we have any issues with blockages etc while away.

Bare in mind Stan youll be bypassing your PRV by connecting directly to the drawbar tap.

I replaced my tank fillers with 12mm click ons. Couldnt see the sense in needing 25mm van pipe to take water from a 12mm hose. Could easily do the same to mains if needed

I put an inline JG non return behind the mains filler. We were getting an annoying squealing from the mains fillers non return. Last week i dismantled it jettisoned its internal non return. They are cheap rubbish and more trouble than they are worth anyway

Damn. Im ashamed now. Shhh, dont tell @Drover

The click on fillers are much better, the only issue is you have to watch it. The escaping air from the breather under pressure is fine, but once water starts appearing under pressure you need to back it of, the tank will otherwise starts expanding and you risk poping hoses and fittings. I still prefer it

If you look at the last pages of my old 14ft Expanda I redid the mains fill point, made things so much easier and chucked that dodgy non return and replaced it with a john Guest job. http://www.expandasdownunder.com/threads/drovers-14-44-3.4502/page-18

Fixed the same thing the other day. Unscrew the main line from the inside & quater turn on the fitting and it comes out. The plunger on mine had disconnected from the locking ring and the spring had no effect on the plunger. As soon as there was pressure in the system the plunger closed and cut off the water. I just pulled the plunger out. Fotunately Jayco had put in a John Guest joiner just inside the cupboard and I replaced this with a John Guest Check Valve like this: .

It was about $25 from local caravan parts shop. All done.

 

[Drover]

If you can get some more pipe @megcam and run it from your inlet to under the floor and fit your valve there , one less join inside is always good. I moved my pump to underneath and that removed nearly 19 possible leak points from inside the van.

 

[Hubble80]

What size John Guest fittings are used by Jayco, 12mm or 15mm?

Thinking of redoing mine also.

 

[Drover]

12mm, pretty sure.

Thanks @Drover
