I had a plumber come and do the rough plumbing of my basement bathroom. It passed inspection and then we poured concrete over it. Once we had everything framed up I noticed when measuring off the bottom plate of framing to the center of my drain I'm sitting at 13 15/16". The shower we picked out calls for a center drain location of 15 15/16".
I need to move the entire drain and P-trap directly backwards 2". I did chip away the concrete around the drain and in front of it to get access to the pipe.
I currently cut it back 2" and put in a fernco coupling. The drain in now in the perfect spot and the shower base fits. I'm just concerned because 1. I think when I cut the pipes it wasn't a perfectly straight cut and when joining together with the coupling I'm pretty sure their is a small gap between the pipes inside the fitting. 2. I'm not sure if I maintained the correct pitch and height when I added on the P-trap portion and tightened down the coupling. I made reference marks and used a laser so I'm hoping all is well. I did also pack gravel underneath and around pipes, so it shouldn't be able to move at all.
Before covering my hole back in concrete, what's the best method for moving this drain back 2" and preventing the pieces from moving or losing their pitch? The fernco coupling I used? a slip joint? a slip joint and re pipe the p trap?
Hope I did my best to explain this.
