I am assuming that you are tiling the floor ? if so, are you overboarding before tiling ? if so, taking into account the thickness of the board, adhesive and tiles, you may have to change your soil pipe connector for a flexible one to accommodate the difference in height between soil pipe and wc. also remember you will be needing to mark and drill through the tiles to fix toilet to floor, as as previously said, you will need to fix cistern at new height. this is all assuming you are tiling the floor . also if tiling the floor, it does look like you will need to change either the tails or get longer flexi pipes for the handbasin, as yours do not look like they have enough movement in them to cope with the difference in height. as I say, this all depends on if tiling or not. only reason I mention this is because of seeing cardboard under a wall tile
I’m not tiling. I’m vinyl planking. They are 4,5mm thick.
i actually bought a flexi today in case I can’t get it back on.
the pipes to the flexi leads have isolation valves so I can leave the sink unconnected if they don’t go back on.
I presume new flexi leads are a cut and bolt job and not pipework?
to answer your question, no, there are boards down already in good shape, and I have levelled a few uneven spots.
I was hoping 4.5mm wouldn’t be too much for the soil pipe...it has a flexi bit on there I can see.
happy with drilling tiles I have already done so and confident I can screw at the bottom.
one other thing. The cistern feed has a valve on it, but it’s been caulked. I can scrape it off, but I’m unsure why it was caulked. I wonder if anyone knows if this is standard practice or better off just isolating at the mains.
I’m hoping to do this later today so if you or anyone else can answer this fairly rapidly I’ll be ever grateful!
