The kitchen sink and dishwasher are on the other side of this wall. The current area used to be a carport that was converted to an extra room. Whoever set this up before we got the place plugged the pipe with something I'm not sure of and covered it up with spackle and painted over it, 6 years later, whatever was used to plug it came loose and water from the sink and dishwasher soaked the wall and carpet. This was behind a couch so it was not easily detected.

Fast forward, ripped the carpet and dried up the area a bit and inspected the damage. I will cap the pipe properly but am not sure how to patch the hole. I don't mind if the cap is protruding since it will be covered.

Ideas and suggestions much appreciated. Pics to follow.

Hi Reybie:

Looks like an old trap adapter fitting. The previous owners probably had a laundry sink or something similar back when.

As you figured, teflon tape or pipe dope the trap adapter and cap the fitting. You can always use it as a cleanout in case the kitchen sink backs up down the line... ;)

In terms of patching the wall, I'd recommend that you remove all remaining questionable areas of the old plaster around the fitting and then install a wall patch screen... see image. You will of course, need to cut a hole for the cap/fitting in the mesh patch. They are available at all home improvement stores. Use a basic fast-drying patching compound to fill the depth of the patch and then use a quick-dry joint compound to feather and blend the edges with the finished/textured wall.

You could also install a 3/8" or 1/2" sheetrock patch and then tape the seams and joint compound the patch to match the finished wall. If you do this cut out a slightly larger, square hole in the existing wall for an even stronger patch... also easier to cut a square piece in sheetrock. F.Y.I... Home depot and Lowe's sell 2'x2' patching sheets of sheetrock.

Let me know what you think...

Thanks for the suggestions guys. I will go to the local hardware and get some materials and the cap to seal off that pipe for good. If the lays low enough to get covered completely, I think I will just hide it, I didn't even know it existed after 6 years LOL.
