First off thanks for any time you spend helping me to understand the finer points of the plumbing world behind the walls and under the floors. I have done some small repairs to the standard house hold P-traps and copper work but I have hired a contractor to take care of the installation of all plumbing work (including the shower kit) in the basement bathroom I recently framed.
The model of the shower kit can be found at the link below:
I will get some pictures and post up if needed but I hope my words can describe with enough detail the problems that the plumber is telling me. He says that the type of shower kit that I have will require to break-up the concrete around the preexisting rough-in. The main issue is that the foundation floor is flat around the rough-in and the drain for the shower kit sits neatly flush with the floor. The drain the plumber bought and showed me has ~1/2" of clearance required underneath the shower kit to work properly.
Just to clarify, the rough-in is a 2" PVC pipe about 10" above the basement foundation and capped. I have done some reading and will test when I get home to see if a P-trap was installed by poring water into it. He is unsure if the rough-in was for a shower or tub; which concerns me since in 10 minutes of reading I found that a typical rough-in for a tub is 1.5" drain and a shower is 2".
Anyway, any advise aside from getting a new plumber would be extremely helpful. Links to the correct type of drain or what needs to be done to make the shower kit I have work with the already existing rough-in would go a long way in getting this complete. The framing around the shower kit is pretty good if I say so myself and I've already had the base sitting in the spot with the existing rough-in going directly up inside the drain hole. Now I just need to figure out how to get water down it!
Thank you again for the time and expertise that you share.
