I am having a renovation done to convert an attached garage into a wheelchair accessible bedroom w ensuite bath. the plumber punched a hole in our foundation to run a PVC sewage pipe down the inside of the basement stairs. This impedes the stairway to 31.5" vice the required 34" req by Code. The local building inspector seems to think they should recess it a bit to meet code. IF recessed to the max at this point, the clearance would still only be 33".
In addition, there are water pipes coming out of a beam at eye height on the same stairs. What do I do?
The water pipes are easy they can be moved shaped and bent to go almost anywhere. the drain on the other hand is a bit harder, it needs to be at a certain grade etc to work properly. Judging from the pics posted, if it was one of my jobs I would ask if those stairs seemed rather steep, maybe, just maybe in fixing that, may fix the drain problem. the contractor and plumber working this job should have been aware of what was going to happen here and presented alternative options before proceding.
Have the plumber run his main line in behind the steps and come down the outside of the stairs or on the underside of the stairs. He then should be able to pickup the main in the floor for tie in.
Hope that helps.
