I am removing a wet bar and turning it into a closet (ugly ugly wet bar and I have no closet space in my home, I guess the prior owners enjoyed drinking in clutter). I pulled out the cabinet and the plumbing for the bar is coming out of the concrete slab. There is a pvc drain pipe coming out of the slab and there is a vent pipe going up from there also. The copper 1/2" water line is also coming out of the slab right next to the drain pipe. I am removing the entire wall that the plumbing is in. In the end, I need a flat floor to put flooring on and a flat ceiling to sheetrock. I live in a two story house and this is on the first floor.

Question: can I just cut the drain pipe below the surface of the slab, cap it with a pvc plug, cut the copper water line, cap it with a compression fitting, and then concrete over both of them to make a smooth floor? Then can I cut the vent pipe off in the ceiling joist space and plug it and sheet rock over it or will I need to also cap the vent pipe on the roof as well? I am getting a new roof probably this summer and can remove the vent pipe from the roof at that time. Will the vent pipe, if I cap it from above, mess up other fixtures in the house?

Any help is greatly appreciated.


So, I noticed that several people have viewed this post, but no answers. This leads me to believe that this may be a topic of interest for folks who are also looking for the answer. Well...

I was able to obtain some information on my own from other sources. First, regarding the drain pipe and supply line. I can cut it below the surface of the slab, use a pvc plug to cap it and concrete over it. Same with the copper supply water line; however, the cap must be a soldered on copper cap. Compression fitting should not be used. Once capped, both can be buried in concrete and the floor smoothed over.

Regarding the vent pipe. The vent pipe should be capped in the ceiling also using a pvc plug and can then be sheetrocked over. The vent should not be capped on the roof or removed because the vent pipe ties into a system of vent piping for the whole house that vents out of the roof and capping on the roof will really both the whole system up.

I hope this helps those that my desire this information
