[QUOTE="Paula, post: 800863"] OK, I think we have [U]finally[/U] found out why my wetroom shower tray has suffered from permanently wet grout ever since it was installed 18 months ago. When I rang Impey for the second time (prompted by the post above), I was told to check two things: 1. that the stacking height adjustment rings in the drain had been glued together properly and weren't letting water escape from the drain as a result, and, 2. that the tiler had placed enough adhesive under the metal frame that holds the drain grille in place. I was told that the frame could easily be removed without invalidating the Impey guarantee (it does not come into contact with the membrane), although it would probably get scratched in the process, so they would send me a replacement free of charge. Apparently if there is not enough adhesive under the frame, as soon as any weight is placed on the drain (eg by someone standing on it) then the frame wobbles, then the grout around it cracks, and water can collect under the void underneath, leading to permanently wet grout. When I looked carefully at my drain again, I noticed that there was a fair amount of cracking of the grout around the frame, and that when I pressed on the frame, water could be seen to be oozing out. It took a while for the builder to send the plumber and tiler back, but they came last week and removed the frame and.......surprise, surprise.......there was no adhesive under the frame and a large puddle of water! I attach a photo of what we found. The stacking rings were glued correctly, so no leakage here. The tiler has now placed plenty of adhesive under the frame and re-grouted with epoxy grout around the drain (to match the rest of the shower tray) and we are waiting for it to dry out properly before using the shower again. Hopefully, this will be the end of the whole sorry saga. I only wish that Impey had thought to tell me to check these two things the first time I phoned their technical department nearly a year ago (at the time they said that our problem was most probably the result of the tiler "dotting and dabbing" adhesive under the tiles, and therefore water was allowed to collect under them - something the tiler always denied). Interestingly, Impey told me that, just after I had purchased my drain (Spring 2014) they changed the design to incorporate weep holes, so that, if any water does find its way under the tiles, it can seep into the drain and down the waste pipe. I only wish we'd had the new design! I hope that this information will be of use to others experiencing problems with wet room shower trays staying permanently wet, even if the tiling appears to have been done correctly. It seems that the correct application of adhesive and grout around the drain itself is of great importance (something our builder and tiler seemed unaware of). Needless to say, I'll keep you posted if this doesn't solve the problem once and for all! Thanks, Impey, for monitoring this thread and finally shedding light on our long-running problem.
