Leaking showerlay

[AliGage]

Scrap that I just zoomed in. Its your seal thats leaking. There's two droplets formed on it. Trap not done up tight enough.

 

[Qwerty]

I have to say I'm confused. I have never ever seen or fitted any that have metal visible within the tray.

I personally never Silicon as the rubber compresses fully to make the seal.

Here are a few more photos he has forwarded to me...

Trap was absolutely bone dry when I took the photo. The water was definitely seeping from the edge of the ply.

Stupid question,
is it tiled yet?
if so, can you take a pic?

 

[Chalker]

How is it sealed round the edge of the square plastic round the grille?

might sound even worse here.... was it tanked?

 

[evilmango]

It's tiled. Grout has had a few days to dry. Used a Bal single part flexi and Ultra Flex Joint grout.

You can see the skirting isn't in yet but it's all tanked so should be waterproof (have only been aiming the showerhead at the centre anyway).

 

[evilmango]

The top of the showerlay and marmox board elsewhere in the room wasn't tanked other than tape over the joints at the edges.

I believe the tiles are just seated into adhesive around the edge of the plastic - will have to check with the tiler. Does this normally need sealing? My understanding was that you could simply tile straight onto showerlay.

I think there is an issue with the tanking here

 

[AliGage]

I still think its a leaky trap

I checked all the tanking before the tiles went down - Schluter Kerdi matting applied to all walls with Kerdi Coll, then joints taped to showerlay with Kerdi tape, then reinforcemens glued in the corners. The only exception is the righthand wall where the tiler ran out of Kerdi matting so used a sheet of Homelux wall.

With all that said, whilst testing it I've been very careful not to get water beyond the centre of the floor so I don't think it's even getting close to the tanked parts.

How long had that sealant been left to go off befire running the water.
The bubblie type look to the Silicon in picture two suggest to me the Silicon has got wet before its cured, long before

Ok hold up... I've just found a piece of ply which looks like plumber has cut out today with a multimaster or similar. Looks like the builder did not cut out a recess for the horizontal pipe earlier. Whilst he hasn't visibly damaged the underside of the board I'm going to guess this probably wasn't good for the drain fitting?

There's that word - "builder".

Investigation over.
Case closed!
