I've just noticed that my 2 year old shower is leaking from the waste (proven not to be from elsewhere). I suspect the joints just need tigtening.The problem is, I cant access the waste now.
The tray sits on the chipboard floor. Its a long tray, and if I cut a hole in the floor ouside the shower, I wont be able to reach the joints to tighten them. I tried stretching my arms to no avail ;) To go in from the side looks impossible as the joists run paralell to the direction of the tray, and I wont be able to get to the trap through the joist.
Has anyone invented a sealer that can be poured down the waste and seal the leak? Radweld style?
