Rear shower connection leaking

[mehandforth]

Hi everyone, our rear shower connection leaks every time you turn on the tap inside the van. Aside from making a mess in the boot, it wastes water. Any ideas? Been searching all over and can't find anyone else with this problem... It's a 2018 T6 Ocean. Thanks!

I had this. You could plug the shower in as a temp plug. Make sure the collar is locked back when you unplug. If its stuck forwards it does the boot flooding trick. I have fitted a ball valve behind mine in case it happens again. Stick a terminal driver up it and jiggle it about. Then firmly plug the shower in. And when you remove it make sure the collar goes back and stays back to shut the valve. I bought a new one but my fix has worked .

I have the same issue. The water pump started all of its own and flooded the boot. After that every time I turn the tap on water floods out the shower outlet at the rear. It's a 2023 T6.1, so I can still take it back to get it sorted, but wonder if there is a simple fix or something obvious I'm missing. Can't find much on this issue out there. Thanks in advance.

Simplest fix is to plug the shower in and leave it plugged in. Then the shower head itself will stop the water.Other than that try plugging the shower in and out a few times to see if it re seats the ball. Worked for me. Bought a new valve but been fine ever since. My issue was that the shower hose also had a hole in it so I had to do a Bush fix at the time.make sure the collar stays back when unplugging the shower. I can't see any detrimental affects of my flood 3 years later

Had this recently, Ocean 24. Booked in this month, it's intermittent though. Also something related to the pump/switching appeared at the same time, when on EHU. I'll post what the outcome is.

FIX for leaking rear shower - I've spent some time on this and managed to sort it. This issue is down to a design fault in the way the water system works. There is only one pump in the water tank which goes into Y connector as it emerges branching to both the tap and shower outlet. The pump is activated either by the tap or the rear shower switch and water then should take the path of least resistance, ie if the tap is turned on it comes out of the tap, if the shower outlet is turned on it comes out there (as the tap is turned off). However this set up means the system is sensitive to how the pipes are physically sitting or any partial blockages. If the pipe to the shower outlet moves from its installed position the path of least resistance when the tap is turned on can then become the shower outlet. In my case the shower outlet feed was attached to the underside of the tip of the water tank enclosure by a sticky pad. This had come off the the hose had dropped down creating a straight run for water out of the shower outlet when the tap was turned on. Where it previously would go to the tap it then went to the shower outlet. A partial blockage of pipes would also change the characteristics of flow.

It can be fixed by ensuring the the shower pipe is fixed properly so it comes out of the Y adapter, and goes up before coming down to the shower outlet. However the design is inherently poor so there is ongoing potential for leakage. I've therefore incorporated a more permanent fix by:

1 - Adding a 10mm inline valve into the shower outlet in the water tank enclosure (some others had posed this solution on there previously). See photo.
2 - Permanently connecting the shower fitting (thanks flying banana) and adding a pocket onto the rear enclosure to keep in in. Makes it much more accessible.

Fabulous answer. Thanks @JonnyOB

We have only used the shower a few times, and not for a year or more. A couple of days ago the shower connection started to leak whilst I used the sink (fortunately my wife was behind the open boot at the time).

I followed advice as above and connected/disconnected the shower several times (and added a little silicone marine grease to the connecting parts) which presumably reseated the ball as the leak stopped.

I can imagine a serious problem if the sink had been used plenty on a road trip, and the shower leaked inadvertently, whilst we were fully packed (I often hide computer and other valuables not far from the shower terminal).

I have ordered a 10mm ball valve to fit as @JonnyOB in #6 above. I don't want to permanently leave the shower connected - though I accept this is another fix - because I like VW's neat solution as supplied, and I am mindful, as @flying banana in #4, that the shower hose could also leak (this has happened with my home shower more than once).

I suspect that a little lubricant on the shower connector and perhaps more regular use of it is all that is required, but I like the 'belt and braces' idea of adding a ball cock as well which I can operate along with the adjacent gas top valve before trips etc.

Fitted a ballcock today:

4 Pcs Hose Clips, Worm Drive... https://www.amazon.co.uk/dp/B09YCKG691?ref=ppx_pop_mob_ap_share

The hose lips are necessary on this ballcock and need to be tightened well to avoid leaks.

Sorry if I'm being dumb, but why wouldn't you simply replace the iffy sliding collar QR bulkhead fitting ? . . . to fit a second valve upstream of it just seems clumsy and unnecessary, when you could just fix or replace the one you have already? Apologies if I've missed something rather more subtle !?

Differently to you, I saw it as a failsafe move. A little like with the van’s gas which has three valves in line.

I think I was influenced by others having a similar problem, the thought of an unseen leak, the apparent unreliability (as posts above) of the specific ball valve connector (perhaps with our very rare use exasperating the problem) but above all I thought my fix was easier and cheaper than replacing the existing valve - though I never even thought to investigate replacing the valve, since after lubrication my shower connector probably functions as well as any replacement.

Understood !
