HELP! Water leak under shower base!

Post by Greynomad »

HELP!
Our Winnie Explorer has apparently sprung a water leak UNDER the shower base - an apparently fully enclosed area with no obvious access panel.
Came to notice when the water pump (which I had forgotten to turn off after our pre-trip tank flushing) began cycling almost continuously as we were about to head out of home base.
Frantic unlocking of house to retrieve keys & get into Girt. By the time we got inside, water was flowing down the floor toward front... managed to grab towels & stop it soaking fwd cab carpet, but there is still a leak somewhere. The towels we laid as a precaution before attending friend's birthday lunch were soaked by return at 3pm.
Second mop-up seems to have cleared that, so not sure if it's a "still leaking" situation or "last of the previous leak" draining out. We'll check again in an hour.

Does anyone know how to access the under-shower area?

I'm hoping that it's just a joint/T-piece which has popped and can be reattached... once I can get to it. Tried levering plastic edging away from panel at front, but no go. Cracked the panel slightly. May be glued in place. Can't cut away trim strip either... too well sealed.
The pump was cycling so fast I suspect it was pumping through an open hose-end, rather than a split which I would expect to take longer to cycle up to enough pressure to re-open.

All advice considered... but please make it fast. We were planning our getaway for Tuesday; hounds booked into kennels an' all.

If I can't access & solve it myself, it looks like an emergency trip to Prestige Caravans, Geelong on Tuesday morning. :(
(Faster to get there than trying for Roberts Winnebago in morning peak-hour!)

I would be sliding beneath the MH in the vicinity of the shower as a first option, you may be able to trace the plumbing.

I'd be more inclined to try to access the area behind the taps. If it's popped a hose there it would run down inside the wall & under the shower base.
Does the shower have seperate taps or a mixer tap?

If the leak is causing the pump to go at a fast rate, its probably a join come adrift, If your mh has water supplied by those plastic hoses the joints should have a circlip to keep them together, our Sprinter did not have these circlips and I had to put them in myself.

I would find the Red and blue hose where they go into the shower and block each one off at a time to find which one is leaking, then look at taking the tap fitting/shower fitting out hopeully the loose end is behind a fitting and not in the wall.

George,
I am no longer physically capable of "sliding under the m/h" :?
Admin,
We have two taps either side of the bath/shower outlet. Can't see any evident screws to remove the chrome surround. Maybe on the underside, where I can't twist down to see?
I feel a groping session coming on. In the nicest possible way, of course. (Hello, Dottie!)
SA Peter,
I had experience with those circlips & fittings when our HWS sprung a leak in Perth 18 mths ago. Fortunately a neighboring M/homer was a retired plumber, and carried spares which he gave me.
I'm hoping that's the problem, as they'd all be of the same age. Girt has been sitting dry for almost 6 mths, then I flushed the tank & pipes, but forgot to turn the pump OFF afterwards! :? :oops:

A check of the 'precautionary towels' has shown no evidence of further leaks. Looks like the second 'flush' was just the pipe's final clearance.
I'll keep in mind the choking of alternate hoses to check which one, but Joy says the first mop-up was warm (I'd also left the electric element in the HWS running... :oops: ), so the HOT tap would seem to be Prime Suspect at this stage.
Offer of help from bloques attending the post-Easter gathering has been accepted.
Thanks for the quick responses everyone...
I'll report back after Tuesday.
Regards & God bless,
Ray

Lots of suggestions by PM. Thanks everyone.
Will head for Mukinupin (as SWMBO insists on calling it!) as scheduled Tuesday, in the firm belief that the many hands who have volunteered to help can not only make light work, but water supply as well! :lol:
Dottie suggested a Urologist to fix Girt's leaky waterworks. :roll:
Will report back after Tuesday... or maybe Wednesday... depending on internet coverage. :P
Regards & God bless,
Ray

I had a problem similar to this in the Alpine, luckily there is an access panel on the opposite side of the wall behind the taps. The problem was a John Guest fitting to the taps had split (don't get me started about those crap John Guest fittings). The small square panel to the bottom left of the photo is what the access panel looks like.

Thanks for the clue Craig.
That hatch might have been installed on Alpines precisely because there is no way in on the Explorer!
No hatch - inside or out.
The bath/shower-base is completely boxed in, as far as I can see. Unable to crawl under to check existence of a floor hatch. Hoping someone else can do that for me at Muckleford tomorrow. But JIC, I'm taking a little power saw to make a hatch!
The JG fittings are a PITA, are they not? :evil:

Re

Never had any problems with them, easy to use and I use the locking circlips.

We had a potential water leak under our shower base. A hair line crack in the base that could potentailly open up when you stood on the base, due to insufficent support under the base.

Bought a new base, removed the toilet, installed the new base with support, Not a big cost around $250 for the base plus 3 tubes of silicon but a B.... of a job. Do not thing its your problem though, unless the plug fitting is cracked and broken.

Peter,
Our prob is not IN the shower base.
Water wasn't getting that far. Shower base was dry: water was seeping under the wall between shower & rest of m/h.

Looks like a job for "Super Silicone"! ;)
Or some JG circlips... or some handy wire & chewing gum...
Regards & God bless,
Ray
