First off - thanks to all of you who contribute to this message board as it has a wealth of information.
I am in the middle of remodeling our master bathroom and would appreciate some guidance.
Where I stand now is a 2'x2' demo'd area of concrete from the foundation of the house in order to remove the old drain assembly, cast iron p-trap (found it was cracked once I removed it.
What I am unsure of is how to properly assemble / re-cement the area that I demolished. I've already purchased the following:
2"to2" No Hub Fernco Adapter
Oatey Square Drain w/ clamping ring
2" ABS P-trap
The problem I have is when it comes to filling in the concrete etc to make the area whole again. Do I reconstruct the drain plumbing but not attach the drain itself? I'd imagine I'd want to make the floor flush with the riser portion of the ABS plastic? Or do I install the bottom portion of the drain into the cement and make the cement flush with the bottom portion of the drain? Are there any walk-throughs available online?
This picture from johnbridge.com leads me to believe that the bottom portion of the drain should sit above the foundation slightly in order to properly slope the pre-slope making the bottom drain portion flush with the mortar pre-slope. If so - how much above the foundation?
Is it ok to embed an abs drain in concrete?
Apologize in advance if my post is confusing as it's a lot more difficult to describe the predicament than I thought.
