Leaking showerlay

[evilmango]

I've just had a wetroom installed. I specified the components and went for a 1000 x 1000 offset Showerlay and 20mm Marmox board onto 22mm ply, with Schluter Kerdi matting for tanking (with the all the necessary glue, reinforcement corners etc).

Plumber came in today to fit the shower head and Dallmer drain. When he went to give the system a quick test he discovered the floor leaking. It seems to be coming from around the drain (but not from the drain connection itself).

I was wondering if anyone has had any experience of showerlays leaking at all? My general impression from reviews is that they're pretty solid, as long as they're installed properly.

Seems to be coming from? what can you see?

Never had any issues with Marmox trays. Rate them highly infact.

Likewise. I would struggle to believe it is the former itself

Cheers, sent over. I'm wondering if the square cut out has caused problems? I did note that the showerlay instructions specify cutting a keyhole shape hole.

I can see straight away what I think is the issue..... It looks as if you fixer has used a thin sheet of metal to support the plastic part of the former, but in doing so this will not make a tight seal between the trap components and former.

Fairly certain that metal sheet is part of the showerlay itself. I can't find a good photo, but you can just about see the underside here:

No, that part is plastic. No metal on the showerlay. I've fitted countless numbers of them with no metal and no failures

I've just undone the drain. I could be wrong but I swear the metal is definitely part of the tray - the hole is an absolute perfect fit, it's bonded both to the plastic upper and it sits flush into the board when looking from the underside. Will email a couple more photos.

Can you email a pic from above.
i think you are correct with the metal plate. It is fitted to some. Has the square fitting that is bonded to the top of the tray been moved?
i usually make the trap up with a good quantity Silicon too.

How thick is that ply?

Ply is 22mm. Trying to get some more photos uploaded.
