Hi,
I'm planning on building a shower pan using a mud bed, Kerdi drain, and Kerdi membrane. There is a box shaped hole around the shower drain that I plan to fill with gravel followed by filling with Quickrete 5000. I was dry fitting an ABS Kerdi Drain on the shower drain riser and noticed that the riser is not perfectly vertical. It is about 4 degrees off from vertical.
It appears that if I want to install my shower pan properly, the shower drain riser has to be close to a perfect 90 degrees. The position of the drain hole is very close to where it needs to be as it is equally distant from the 3 walls and where my proposed shower curb will be. The top of the riser is about 1 1/8" below the top of the concrete slab. I've marked the various distances between components in the attached image.
There were three options I was thinking about to fix this situation.
1) Cut the ptrap off at position Cut_A and replace with a new ptrap and riser and try to make it level.
2) Cut the ptrap off at position Cut_B and replace with a new ptrap and riser and try to make it level.
3) Cut riser at position Cut_C and try using 22.5" couplings to make it level.
My questions are:
1) What do experts on this forum think is the best methods to make the shower drain riser level?
2) How do you measure the levelness of the shower riser? I'm using straight levels held up against the pipe but is there a more accurate way?
3) First time I'm doing this. Are there other things I need to consider to get this done right?
4) Would there be a way to not touch the pipes and use the mud on the mud pan to hide this imperfection?
Thanks!
