Re: Want to relocate main water line in pantry


Should i use that cpvc under the house? Is it a bad idea to attach regular pvc to cpvc? It looks like the original plumbing switches over to the regular pvc once inside the house and back to cpvc when it goes back underneath.

Re: Want to relocate main water line in pantry


I would use all CPVC. PVC can only be used for cold water lines and some codes do not allow it in the dwelling. Ask you local AHJ.

Re: Want to relocate main water line in pantry


As far as the 2 holes that are in the floor what's the best option for covering those up? I have that vinyl linoleum floor stuff in the pantry and kitchen. One hole has a piece of pvc in it and it appears to have been glued and will not budge so it's filled with caulk so I won't have a highway for mice to get in my house. The other hole will be near the corner of the pantry with nothing there

Re: Want to relocate main water line in pantry


Do they make a recessed box for a main shut off valve? I cab only find then fir refrigerators and washing machines. Guess I could drill a hole in the top of a refrigerator one so pvc will go through....

You don't need a box, just put in in the walk with a plumbing access cover.

Re: Want to relocate main water line in pantry


If you simply use an access panel, the pipes and shutoff will be inside the wall. The access panel basically covers the hole you cut in the drywall, but allows you instant access to the shutoff. Some have frames around them and the center pops out of the frame when you need access and there are others that are simply spring loaded and have no frame. Search at a big box for "access panel" to see the barious types.

Re: Want to relocate main water line in pantry


I have cut the hole and was a little surprised. Both pipes stop in the wall and do not go up. There is also an unexpected stud between the 2 pipes so I wonder if I can fit an access panel in the small corner for the main water line.. I plan to just cut off the 90 degree stump on the hot water side and capping it and cutting the main line at the 90 degree mark and attach the line to that pipe under the house with the valve at the top in the wall. The wire is simply stapled to the stud so I'll pry it off and do away with it.

Re: Want to relocate main water line in pantry


It apears to me that this pantry may have been a bathroom in the past, since those look like sink stubouts.

Regardless, you can get the frameless spring loaded panel and will not have to worry about the studs. I believe they come in various sizes starting with a 9x9. As long as one edge of the hole is cut relatively square it doesnt matter what the opposing edge looks like. The framed ones will also work assuming that your drywall is at least 1/2" thick, but the hole will have to be square.

Re: Want to relocate main water line in pantry


Those pipes went to a water heater tank and it was capped off by the plumbers who installed my tankless

Re: Want to relocate main water line in pantry


Just had a thought. Right now the main valve is before the wall so if I cut that pipe off at the wall and connect the main line to the pipe in the wall it seems like it wouldn't do anything. I'll be bypassing the valve right? Might have to put the valve under the house anyway.

Re: Want to relocate main water line in pantry


To be clear, it looks like your current main comes up through the floor and has an existing shutoff on it. It then crosses over into your hole. It cant simply be capped, since you would have no water in the house. Therefore, i have to assume that the cold water pipe goes down into a basement or crawl space snd branches off from there. A picture showing the cold side (inside the hole you created) eiuld be helpful, but ot seems to me that under this room you could join the incoming supply to the horizontal and eliminate the pipes that are in and stub out of that wall. If you want a quickly accessible shutoff for the whole house dimply bring a loop from the basement up inside the wall across for a few inches and then back down. You could install your shutoff on the vertical part of that loop and leaveca hole in the drywall there covered with an access panel. I would highly recommend a ball valve rather than any other type. For the old hot stub, just eliminate it from below by removing the "tee" and installing a coupling. That eould take all of the pipes out of the pantry.

Re: Want to relocate main water line in pantry


The main comes up through the floor, goes up about 5' and then into the wall I cut open. Then it goes down and does branch off. What confuses me is how the valve turns off all the water. The main line comes in the crawlspace from the well and into a pressure tank. From there to another pressure tank and then across the ground to where it goes up into the pantry. Before it goes up it spills and goes to the outside hose. Some how that valve still turns off that outside water too even though the pipe splits before the valve

Re: Want to relocate main water line in pantry


Also, how do I remove these caps? It just spins and won't pull off either.

Re: Want to relocate main water line in pantry


You need a Sharkbite removal tool or cut the pipe.
