We are currently heading for QLD and are in Armidale. Had a shower this morning and heard water spraying in the wall cavity of the shower buggar.
Our van is a jayco heritage 2007 model, there is a removable moulded piece with hot and cold taps I am considering taking this off to have a look hoping to find the problem which I know is in the hot water line.
Any one else had this problem and able to provide advice.

Hi, we have just been down this road with our Concept, a broken john guest fitting behind the mixer tap, talking with my Jayco owner brother his said his 2005 Jayco had 2 taps on a panel, by removing 4 screws he was able to repair the leak but our case with a mixer tap only way in was via cutting small just above the tail lamps then covering the hole with a false vent.
If it is like our Sterling then the plumbing could be plastic tubes. Last year while away the pipe under our en suite split causing water to spray everywhere. A temporary fix was made by buying a short length of heater hose (actually, it turned out to be hydraulic hose) from one of the Auto parts stores, cutting the split section out and putting the hose over the gap as a sleeve and fastening it with worm drive clamps.
I said the repair was temporary because a couple of months later the pipe split again further along.
Anyway, If the plumbing is indeed plastic then it will be a system called John Guest. I ended up simply buying a length of pipe and replacing the section which was a little bit less than a metre.
The mail order firm Caravans Plus in Queanbeyan NSW sells the plastic tubes in three colours - blue, black and red - for $1.85 per metre plus postage. All my plumbing was 12mm size tubing.
(No affiliation, except their prices have always been good. And fast delivery.)
Check out You Tube for videos of how to remove the tubing from the connectors - search for John Guest fittings. The tubing simply pushes into the fittings, and pulls straight out after the release is pushed in - hard to describe but the You Tube demonstrates it.
Then again, you may be lucky and find that the tube has just come out of a joiner fitting and only has to be pushed back in!

PS: The photos on the second post show both sizes of the John Guest piping - 12mm black and red inlet and 15mm outlet from the mixer. Because the John Guest system simply pushes together you do not need a plumber to do any repairs.

Actually, to extract the pipe/tube first remove the red locking circlip. Then simply push in the ferrule and withdraw the pipe/tube.
To replace the pipe/tube slide it in as far as it will go. To lock it in pull out the ferrule and clip the locking circlip back in place.

Nice to meet a fellow grey nomad this morning. Our water problem was the John Guest fitting on the hot pipe of the hot water system. Have a safe trip to Clontarf and we hope to see you again.

Tips for John Guest fittings.
ALWAYS use a collar insert in the pipe ends before pushing the pipe into the fitting. This ensures that the pipe retains its shape in the long term so that the joint won't leak or come apart.
Also, where the fitting has a 'nut' like moulding, don't be tempted to use a spanner to tighten the fitting. To do so will probably lead to an immediate or subsequent crack in the fitting.

Good advice, I have a hand full of those grey collar inserts to add to my joins as I am working on the caravan.

PE-X piping as used in this type of system is normally fine with vibration etc - what they don't like is direct sunlight. I wonder if the builder has cheapened out and bought in lower quality PE-X piping from China or elsewhere. This type of system is now the bulk of new house builds in the UK for both hot, cold and central heating!
Edit: Don't be tempted to re-use joins after a couple of changes - they are cheap enough so replace them.
