Plumbing the water supply for a new shower (in an OLD house!)
Hello,
Background: I am installing a shower in the basement half-bath and am trying to figure out the best/easiest place to tie into the house water supply. I can access the main lines running horizontally through the basement via a neighboring closet. There is a spot on the main hot and cold lines that has a 4-5 inch vertical stub that’s capped.
Question: Is there anything wrong with just cutting the caps of the hot and cold vertical stubs and tying in there? The reason I’m questioning it is I’m not sure of the function/purpose of those vertical capped stubs and don’t want to inadvertently hose something up. There are so many other connections into these main lines there really isn’t another good place to tie in that’s anywhere close to convenient….
Thanks a ton in advance!!!

Those caps are probably homemade shock arrestors. But a bit small. Would need to see a pic..
I would be more concerned in how you are tieing in the waste line in a half bath and getting it vented properly...

Mike,
I'll see if I can get my wife to shoot me a pick. For the waste I took out a CI floor drain, installed the shower drain and moved the floor drain. so it's 3" floor drain --> 3in to 2 in wye --> back into the CI. Used a AAV to vent (I know, some hate 'em). Worked through the DVW with the plumber so I'm confident it's OK. The supply is the next issue. Pic to come.
Thanks,
Brad

Finally got the picture. I'm trying to determine if it's OK to basically cut off the cap on the vertical pipes in the picture and run these to my supply lines for the shower. Thanks again for your help!

Yes I understand now. IMO cut the caps off and install two ball valves. Then go from there...Probably put there for expansion as you are doing...
The floor drain originally should have been vented already and no AAV would have been required..

Mike,
Thanks a bunch! I was hoping there wasn't other function I was missing or unaware of. As for the AAV, the vent for the floor drain was/is maybe 15 feet away so the plumber I had out for a consultation recommended an AAV. The nice thing is it's there (since the rest of the drains are now under concrete) and can run to a vent later, leave the AAV or cap it. At least there's options (that don't involve concrete work)!
Thanks again!

Is that a abandon gas line to the right in the photo, the black pipe with half a union on it. I would make sure it isnt tied into your gas main and just valved off. If it is put a cap on it, valves can get bumped or opened on accident.
