 Toilet Drain
Author: OZ (AL)

Hello everyone!

I am in the process of redoing my sister's bathroom and recently had the tile installed. There is about a 1-3/4 inch to 2-inch wide x 5/8 inch deep area around the waste drain pipe (3 inches inside diameter PVC, with a temporary cap to keep the cockroaches secure).

1. Should the area around the waste drain floor be filled up to the level with the tile? If so, what would be the
best material to fill it with? (subfloor is CONCRETE)
2. Which flange would you recommend using?
3. What would you recommend I use to cut the waste drain pipe?
4. I have replaced toilets before, but this is my first flange. Is there a way I can easily set the toilet down
onto the flange by myself, or is it better to have someone else help?
5. Anything else I should know, or be aware of?

Thank you!! Adrian

yes, the tile 'should' have been closer (i like 1/2" clearance)

but no disaster

simply buy some 'self levelling filler' for concrete and clean the gap with a good wire brush before pouring

let set as per instructions

then purchase a PVC flange for 3" pipe and 'chip out' enough clearance for a back of flange on top of finished floor installation (you will see what is needed when you have the flange 'in hand')

THEN cut the pipe flush with the finished floor and solvent weld on the flange

principle of cut:

simply tape one end of a 16T hacksaw blade for your ONE cut

secure the flange to the concrete subfloor with stainless steel 'tapcon' screws
