Onoff Posted November 27, 2021 Share Posted November 27, 2021 Rip it out and start again. Clean all the silicone off of it, every last bit. Was the trap the same make as the tray? Sometimes the trap rubber washers are generic thus a bit of a crap fit to that particular tray ( so said your uncle way back). I can only go by what I did and the tips given. I ditched one washer and loaded with Sika EBT. The top side has come out really well IMO. I wasn't overly fussed about underneath. Baby wipe around and walk away until set: Did the same with the overflow: 1 Link to comment Share on other sites More sharing options...

Monday I’ll attempt to rip it out . Might try the multi tool under neath to cut the trap in half or something …. Link to comment Share on other sites More sharing options...
Pocster Posted November 27, 2021 Author Share Posted November 27, 2021 Well ! The cover ( what do you call the bit that screws in from above the tray? ) came undone easy - too easy imho . Not touched the trap - but it looks like a decent seal .. ( but isn’t ) . Getting the trap out easy now . Recommendation for a new decent trap etc. - screw fix link appreciated !

Gone West Posted November 27, 2021 Share Posted November 27, 2021 (edited) I used McAlpine Hi-Flow shower wastes at our last place. No leaks. https://mcalpineplumbing.com/traps/shower-traps-accessories/st90cp10-hp2c-112-90mm-hi-flow-shower-trap https://www.screwfix.com/c/heating-plumbing/traps/cat831610?trapapplication=shower#category=cat831610&brand=mcalpine&trapapplication=shower Edited November 27, 2021 by Gone West 1 Link to comment Share on other sites More sharing options...

I didn't use any silicone but did check the surfaces were flat and smooth. IIRC I used silicone grease on the outlet compression fitting. Link to comment Share on other sites More sharing options...
bassanclan Posted November 27, 2021 Share Posted November 27, 2021 Use CT1, both above the tray and below. Every time you undo it there's more likelihood of damaging the rubber, so do it bombproof once. +1 for the macalpine, available in Screwfix or Toolstation (just check the size of hole in the tray) 1 Link to comment Share on other sites More sharing options...

Thought it was strange the supplied one had none . Link to comment Share on other sites More sharing options...

You can fit without top rubber (some people think the black rubber looks like mold so don’t want it) but then needs a good flexible clear or white ct1 or silicon 1 Link to comment Share on other sites More sharing options...
Pocster Posted November 30, 2021 Author Share Posted November 30, 2021 (edited) Fitted the mcalphine . Seems a much better fit. Rubber seems much thicker ( SWMBO told me about this ). Had a slight leak on my glued pipework ; up a ladder , limited view, limited light so will forgive myself. Tiger sealed around those joints. So full test tomorrow when SWMBO showers. Also 'cheated' a bit ( but again will forgive myself as accessible ) and fitted a flexicon onto the new pipework again to make my life a bit easier. So so far looking promising!!! Forgot!. Tightening the actual trap to the tray (from above ) about a million times easier than the previous trap. Easy to grip; lots of thread - so much better!

ProDave Posted November 30, 2021 Share Posted November 30, 2021 All this leaking / dripping pipework worries me. Does your BC insist on a drain pressure test? They do up here and I would be surprised if yours passed that. Time to find out NOW if they do, and ensure it all passes. You don't want to be finding out at completion time they need that test, and it fails, and it's all boxed in. Link to comment Share on other sites More sharing options...

During the entire build they have effectively checked ZERO even when I call them out at ( what I think! ) are important points. Link to comment Share on other sites More sharing options...
ProDave Posted November 30, 2021 Share Posted November 30, 2021 Perhaps someone else in the Bristol area might comment if BC want to see a drain pressure test done? All I know is Highland council WILL want to see that, so you want to be sure your drains don't have any leaks before you cover them with plasterboard. 1 Link to comment Share on other sites More sharing options...

One step ahead of you @ProDave ( though appreciate your input ) we are having “ Swindon office “ type ceiling tiles - so all pipework ( good and bad ) accessible. No boxing in for me !
