So I've been trying to install my first shower tray (stone resin). Instructions say it must be on a bed of mortar.
Now I always knew access to the shower trap would be very difficult once the tray is in place. In fact if I put the trap on the tray first and then lowered it down, I'd never be able to screw the rest of the waste on. So being a dafty, (!) I went and spent a fortune on a McAlpine trap, connected it up to the rest of the waste and then got it in the right position under the floor so that when the tray goes down, I can screw the rest of the trap in.
So then the time came for the tray to go down. I added a little bit of puraflex 40 on the underside of the tray (between tray and washer) and then left it until the next day. Next morning I stuck my arm along an access tunnel I'd created (through a brick wall) and could feel damp. So I took it all out.
Then without mortar I fixed up the trap and tested it this time without any silicone and it seemed to hold but its hard to be 100% sure since access is so bad I can only really see about half of the trap body and the flexi connection. (I know fixed is better but would be very hard to do that where this is).
So tonight, I put myself through attempt number two and mortared it up. All seemed fine until the f***ing bas****d leaked again. Thank god I don't do plumbing for a living! Last thing I tried was adding some more puraflex and then I ended up getting the fking stuff everywhere including the threads which meant it was very hard to do up the trap. (And in any case, if McAlipine are supposed to be the best, how come they don't even come with a tightening tool? - my fingers are numb). So last thing I did tonight was to clean it up with lots of "silicone eater" ready for failure number three.
So two days and two lots of mortar removed later, I'm here to ask for some advice. If I don't get any my plan would be to take the tray in a test environment like maybe on some wooden studs off the floor and see if/where it is leaking and also try to simulate tightening the trap when I can't hold the trap body.
