toilet seal, wax or foam rubber
I am putting a toilet in my basement that has the rough in plunbing. The problem is they did not install a flange and cemented right to the top of the drain. In order to save me some chipping concrete work I thought I would install a flange that goes inside the drain rather than over it. The plumber at Home Depot told me I could not use a wax seal but had to use the rubber one. I installed it using the rubber one get a leak at the seal. Why can and I not use a wax seal? I would think that once it gets forced down it would seal much better. Any comments. And as always thanks in advance. The help here is awesome.
