B544 plumbing issue

[pandas]

Discovered a water leak/drip behind the rear wheel coming from some sort of bulkhead. I believe it is coming from under the shower tray/waste trap somewhere, dripping onto the garage floor and making it's way underneath. Any ideas of how access to the plumbing? Presumably from below from the very narrow garage or does the shower tray lift off somehow? Just plucking up the courage to have a go but wondered if there were any hints before I start - apart from the obvious of taking it to a dealer! Thank you in anticipation.

Is it dripping outside the van behind rear wheel or into garage ?.
You need to establish if it's fresh water or waste from sink or shower.
That should give you a starting point

Plumbing was accessible from the garage on my B644 but have you checked the shower tray for cracks.. particularly around the plug holes.. .. ? That is a more likely source of a leak.

The 544 has a drain down plug on the floor at the rear under the drawers. Remove them and check there

Is it coming from the shower tray or could it be a boiler expansion valve/pipe dripping.
I had to replace mine.

You can get to the trap from the long storage compartment under the shower, sit on the floor and you’ll see a fair bit.....

Get someone to run water down each of the drains, (3) one from the sink and two on the shower tray. Sit outside and see if you can see where the water is coming from...
