copper

Hi, this is what I just found behind a wall in my master bath. I am totally gutting this room, and am wondering if I can bump my main vent stack back about a foot to take advantage of all this wasted space in the wall behind it; I will be removing the small wall on the right of this picture for...

Hey folks, first of all thank you for your expert opinions that you share on this site. I've learned a ton from reading on this forum. I'm preparing to replace my 30-year old tub with an acrylic one, and I opened up an access wall to see what was going on. As you can see in the pictures, the...

Second attempt here. My last post got zero replies. Please help! I’m a DIYer trying to renovate my second floor bathroom. Not totally inexperienced, but also not totally experienced. There’s an existing 2-inch threaded copper pipe that used to receive the old shower drain. I knocked all about...

Hello! I’m renovating my second floor bathroom. I want to reconnect to an existing threaded, 2-inch copper pipe that served the old shower floor drain. As you can see from the picture, the pipe extends about one inch above the 1/2 hardibacker subfloor. The plan is to build up a mortar bed...

Hi. Wondering if you all could offer suggestions as to how to plumb my shower/tub combo. I have the Kohler 2971-k-na 3/4" inlet and outlet mixing valve. I'll be bringing up 1" PEX to the 2nd floor the entire way from the 3/4" copper main. This unit does not have a built in diverter and has...

I had a plumber put in a new valve body since I'm in the midst of a complete tear down of the tub surround. I noticed that the copper line (diverter pipe) that feeds the shower head has some crimps in it. It looks to me like he grabbed it pretty hard with a wrench while sweating everything...

My old bathtub faucet/ diverter is no longer working. I go and buy an identical one from Lowe's. I open the instructions and find 4 types of pipes shown in the directions. My type of pipe is not on there... of course. Mine protrudes a little over 3 inches and has threads close to the wall? SEE...

There's a 30 foot run of 1/2" copper hot water pipe that was cut where a compression fitting was installed. I replaced this hot water fitting 3 times with a new one of the same type that was on there that had gotten old and rubber seals dryrotted away which means it was leaking badly. The new...

I am planning out an underground sprinkler system and need to bore a hole through a concrete foundation wall to bring 3/4" copper pipe through. The point where the pipe will come through is above grade, and in a northern/freezing climate. The concrete foundation is roughly 90 years old. I've...

I want to install a thermostatic valve for specialized application. I was planning on screwing the check valves with tape to the valve and then screwing the copper female adapters with tape (pre-soldered to pipe I need) and then soldering my copper to the Tees I would install on the hot/cold...

Hi everyone! I am a senior Managerial Marketing student at Kent State University. For my senior project, I am collecting insight from plumbers like you on plumbing pipes. I will then analyze these results and present a solution and marketing campaign based on your feedback. If you could please...

Ran into this while doing some DIY repairs on a house built in 1949, which was built with under-slab plumbing and under-slab runs to radiators. I found that some of the copper water supply pipe (not radiator) was too fat to accept normal 1/2" fittings. After going completely mentally blank from...

Is there a reason why the IDs for PEX tubing are somewhat smaller than for copper? In other words, why is the ID of (for example) a 1/2-inch PEX tube smaller than for 1/2-inch copper? Do they make PEX smaller on purpose? Is there an advantage to it being smaller? I have always thought of it as...

Hello All, This is my first post but I have been browsing the tutorials and DIY section for a bit. I recently noticed water leaking through one of the door jambs in our house. I took my time and tracked down the leak before drilling or cutting. I found the leak in the three inch copper waste...

I live in San Diego, CA, and I'd like to replace the water supply line between our water meter and house. The current setup is pretty simple: there's a 1" copper pipe covering the 20' span through the middle of the front yard in a straight line, and it doesn't pass under any hardscape. It's...

Can anyone tell me if it is more common to find a 2" copper drain plugged or a 2" PVC drain? Also, Should I just replace the copper drain pipe with PVC? Thanks!

Hi, we have colloidal clay and copper in our well water. Our home is 7 years old and has a very deep (500+ ft) well that I've been told has aggressive water. We have fairly high sulfur so we treat with peroxide, though we also have an H2O injection system that isn't enough to kick out the...
