P-Trap extension

Hello all,

I recently bought one of those toilet suites where are closed off at the back so you cant see the waste pipe. I noticed that the outlet on the actual toilet is too far away from the pipe in the wall. I went to bunnings and they sell a flexible waste pipe which as the wider collar at one end and a smaller opening at the other end. I know the collared end will definitely fit on the toilet end but will the smaller end fit into the collar thats already in the wall?

Secondly, how do you know if it leaks or not since you cant actually see the pipe? Just make sure its tight and hope for the best?

Cheers.

you need to extend the original waste pipe out to suit the P trap of the pan, or better still ask your plumber!!
