Mains pressure feed - Jayco

Dougwe · Chief one feather

Hi Warren, hope you are both well?

Have you thought of changing to 'Hoselink' fittings? I did and have had no problems since. Not cheap but once you have them they will last for ages, even longer I reckon.

Keep Safe on the roads and out there.

Did it used to work ok? I have just bought a secondhand van and the jayco people told me that the inlet on mine is an american gauge and you need an adaptor with the american gauge on it.

The hose fitting i.e. your hose to the supply tap to the 3 way manifold (middle fitting), it should not come off, regardless of whether there is flow or not. The male click on fitting at the manifold does contain a non return valve, and it could stop the flow. It has a flat rubber seal on it, and it can come off. If it has, there is the possibility that it is blocking off the supply going into the van. I would replace this part, available as a replaceable spare, a/ because it sounds as if the click on section is worn ( The female part comes off), and b/ a new non return valve is also integral with this part.
To get at this fitting go to the inside of the van, to where the manifold enters the wall of the van, there will be a push in tube to it, release this, and then give the whole fitting a 1/4 turn either clockwise or anti c/w, and it will release, (like a light globe). Fit the new one in reverse order.
If your hose still blows off, the female fittings on the supply hose must also be faulty. You should be able to see if the seal on the old fitting is blocking off the port. Try your system to see if it has improved.

If that hasn't helped we'll look further.

Thanks for the replies, chaps.
Starting from the easiest -
hufnpuf,
no it hasn't been good for ages. Have got around it by holding the hose on while we've got water for a cuppa, cooking, etc or not connecting at all. I've changed the O-ring several times. American? I wouldn't doubt it.
Doug,
keep well you say! We came to Toowoomba some 6 weeks ago for family issues. Were planning on being here for two weeks but I developed a bleed into my right thigh muscles, week of seeing doctor, week in hospital, went for my first drive today to see how I'd go towing the van back as Pat won't. Think I passed (no shoe in right foot). Bought the automatic car for a reason - health! Pat's back has limited her movements.
Have to be home soon to post the Christmas stuff off, plus son is coming up so we have to be there first!
Re Hoselink, I assume they'll connect onto the van connector(?)
Ian,
yes, I suspected as much. Thanks for your supporting theory. The connectors on the hoses have had little use, have changed them not so long ago.
Will have to wait until my thigh issue goes away!

Douge, we are house sitting up in the Perth hills, the water pressure here is very high. The owners of the house are using Hoselink fittings, and yes I agree with you, can withstand the pressure, American I think. But no they are not compatible with the click on types. Looks like one can only buy them through Ebay.
Warren you have time now to order that fitting, and when you are well enough, your son can help you replace the old one.

iana · Guru

Warren, I am only suggesting replacing that fitting because it may be worn, or damaged. Before we can find a problem with the water flow, your supply hose has to stay connected. Occasionally my supply hose will blow off, but that's because I haven't fitted the "Click" connecter on properly, I have to make sure the sliding part of the female connector is in its home position. It could also be coming off, because the new fittings you have purchased are poor quality. Its hard to tell these days which ones are good quality, they are all dumbed down to be the cheapest to buy.
With that fitting I have suggested you replace, there is a non return valve in it, and in my opinion, it serves no purpose what so ever, probably done for water laws to make sure that your van water won't return to the town mains supply for health reasons. I have removed that valve, as it can only cause trouble, removing it means cutting it out, as its part of the valve.

Problem seems to occur with plastic bodied connectors - I now buy brass fittings and regularly check/change "O' rings. Brass ones are only marginally dearer.

Warren-Pat_01 · Guru

One of my concerns had been how much pressure I could put on that male plug. Up until yesterday. I thought it was one piece but I discovered there is a plate + 3 individual inputs.
I too have always preferred brass (the mains input on our previous Eagle was a plastic nut screwing into a large brass adaptor going back to the click connector (probably more expensive than the junk made in the last ten years)!

Water Inlet.jpg I am assuming we are talking about the same inlet manifold. I agree its cheap and nasty, but it does the job. Ours has been connected to water points all around Australia, and I can assure you that it can withstand the pressures. However a pressure reducer at the park tap is a good idea ($8).

And yes behind the manifold, the center fitting of which I sent a link to you about, has a reducer and a John Guest fitting screwed into it. If you take off, the tube going into the John Guest fitting, the whole unit will come out with a quarter of a twist, that unlocks it.

You need to take it out to see if the seal on the non return valve has come off, and to see if there is any damage or wear on the male click fitting. If you intend to reuse the fitting, I would cut that valve out.

Ian

G'day again Warren,

Take care with the health etc. I hope to catch up again maybe next year if/when I am in Townsville.

Now, I have a metal, what I think is a pressure reducer, with standard garden tap thread fitted to the Aluminium teepee for mains water connection so I just fitted a 'Angled Tap Protector' then the hose to that with hoselink fittings. Once everything is made up, it is so easy and no way can they come a drift. These fitting grip like you know what to a blanket or red wine on a white shirt. Mmmm, the red wine sounds good. I might go see Uncle Dan.

If that pic Ian put up is what you have and it is a standard thread, I see no reason why it wouldn't work.

When I had the Avan Camper many moons back now, I used to adjust mains pressure by only turn the garden water tap on a little.

Keep Safe on the roads and out there.

Warren-Pat_01 · Guru

Yes Ian,
That's it - thought it was one piece until I saw otherwise recently.
It looks like I have some mucking around, courtesy of you, Doug & Possum with it before the next trip (somewhere). I had intentions of getting some work done on the van but then the leg blew up - I recall a saying about the plans of mice & men somewhere in the gravy banks!

Heard today from friends who have been collecting our mail, checking the property & raiding our pawpaws (keeping the bats at bay) that our mango tree has 5 mangoes on it that they can see! It was "loaded" when we left but we get the "knock-em-off winds from August to October so we'll have to wait for next year or else! The tree does harbour some nice orchids!

Warren - they've done a movie on your Jayco pressure problem:

Here's the way I am looking at the problem, Warren says the supply hose won't stay connected to the van, with out water supply he will have no flow, and no pressure, agreed ? So first we have to get the supply hose to stay connected to the van.
When all taps etc. have been turned off, the pressure in the hose, (unless a pressure reducer is fitted at the park tap), will increase to town pressure, The inlet at the van manifold is a male "Klick on" fitting, so it or the female hose connector must be faulty.
When Warren gets the supply hose to stay connected, then we look further if there are still flow or pressure problems.
And the "Klick on" fittings will depending on quality, will withstand town supply pressure.
So that's the logic I am using.

Thanks for the ideas, chaps - much appreciated!
I'll leave it until we get home & then after (I hope) the knee returns to normal size, I'll get into it. I dropped the morphine tablets five days ago, might just have to go back on the 2.5mg one to get some pain relief at night.

I'm making a shopping list, including a new inlet fitting that Ian mentioned earlier. The other side of it is under my bed so it's relatively easy to locate.

I'll let you know how I get on. Hopefully starting the slow multi stop drive home on Wednesday. At least I can drive now with shoes on both feet!

Possum3 · Guru

Warren, try Panadol/Panamax half an hour prior to going to bed - More relief less addiction - stay away from any relief using "Forte" in name - Codeine is also addictive.

iana · Guru

I don't think that this has anything to do with this problem, but it can occur, a while back the daughter rang, saying she couldn't get any water from her garden hose. I tried it and it had me scratching my head, until I found the female "Klick on" fitting she had brought had a built in "one way" valve in them. So those fittings can only be fitted to the hose at the supply tap end, I guess they use them to prevent the operator getting a face full when disconnecting the hose.

Warren-Pat_01 · Guru

G'day Possum,
Pat is a nurse so I'm ok there. Have been taking panadol osteo for a couple of years (a bit stronger than panamax, etc). The morphine is 2.5mg Targin - was on 7.5 but dropped that back to 5, then 0 but the last couple of nights have been a bit uncomfortable so I'm going to the 2.5.

Thanks for your concerns

Warren-Pat_01 · Guru

Ian,
Been there, seen those, have arrows on my click connectors now! The valves work well!
They can be drilled out without any great effort.

iana · Guru

Good to know, take your tripping at an easy pace, remember what you don't get done today, it will still be there to do tomorrow, or the next day etc.

Cupie · Guru

Way back in 2000 I had by first warranty service carried out by a Jayco rep in Perth. I was on a trip round the block.

He had a thing about the water inlet pipe coming adrift inside the van so he changed the input away from the standard fitting behind the hatch & fitted a standard click lock? connection under the van directly below the hatch. I later installed a stop **** & cap on this connection.

To prevent over pressure issues (I have had connectors blow off during the night) I made up an inline pressure reducer fitting that I can screw into the CP tap when I encounter very high mains pressure. This manages the pressure to the van feed.

I always use brass connectors & as part of my annual Mtce routine I replace all 'O' rings with new ones that I source from a plumbing supply mob (not Bunnings). I would prefer to use Hoselink connectors but they won't fit inside my carry tubes that run under the length of the van. I also clean out the anti backflow & filters as part of the annual mtce. routine. Too much time on my hands I suppose. Oh yes .. I have rubber caps that I put over all connectors that I clean before sliding them into my carry tubes. Keeps the connectors clean & seals off the hoses themselves.

About every 5 years or so I replace the brass fittings, as the nylon holding fingers wear out. I've got lots of second hand ones in my spare parts bin 'cause I just can't bring myself to bin them.

Hi fellow Jayco owners,
My van has one of those three way water inlets - 2 low pressure tank inlets & one mains pressure.
The latter hose will not stay on the fitting, squirting water all over the place. I think there is a non-return valve, possibly a pressure limiter somewhere in the feed. Someone suggested removing the O-ring & adding some teflon tape in the groove, then refitting the ring. That was ok for a little while letting water come out of the kitchen tap, etc before the leak started again. I tried adding a pressure reducer at the on the tap but that only let a dribble come out of the kitchen tap & later blew off the inlet when the pressure increased.
Question - have I got a blockage in the brassware under the van or do I need to replace the plastic inlet fitting?

Don't use teflon tape on tap fittings, it's a waste of time. O rings on the male click on fitting should seal by itself, can be replaced quite easily.

Caravan park taps are covered in teflon tape, not needed, the flat rubber washer inside the female fitting should screw up tight against the tap and not leak, again easily replaced if leaking.

You might have a non-return valve that is stuck and not letting any water in.

Cheers Bob
