    Pipe and electrical wire in drywall

    I wanted to install a ¾” PEX pipe in the drywall area (z-axis), but there is an electrical wire just above going into the same area. The pipe water temperature will be 180°F, and on the other side there will be a 90° elbow upward. I did not find any IRC codes on running pipes close to...

    Install PEX tubing above doorway

    I can (A) mount the tubing outside the wall, enclosed in a soffit; or (B) remove drywall and drill 1.2" diameter holes through the king and cripple studs. It would certainly look better without the soffit, but I'm more concerned about inspection. The door/wall run parallel to the joists, so is...

    Ugly pex stub to copper

    Hello! First time posting. The plumber before me left 3/4" pex stubs out of the stucco wall to connect to a tankless water heater. It's pretty ugly and I don't want to rely on the durability of white pex exposed to the elements. Any ideas how I can secure the pex inside the wall, tie into...

    Leak (?) in New PEX 'B' system

    Just installed a DIY Pex B system in a small house I am building. Testing with compressed air at 50 PSI shows pressure drop of about 1 PSI every 24 hours. I am using a delta multi-choice shower valve with test cap only (no cartridge) as the bridge between the hot and cold loops. I have taken the...

    Are Keeney No-Crimp PEX valves more reliable than Sharkbites

    I’m planning to remove Accor FlowTite valves under all sinks & toilets in my home(25 total). I plan to cut these valves with a compact Rigid tubing cutter to reduce the risk of etching the PEX tubing when removing. I’m considering installing Keeney PlumbPak No-Crimp angle valves. I understand...

    Hello You all were awesome helping me with the DWV portion of my DIY project. Now time for the water line rough in. Been reading the threads regarding PEX. I calculated the pipe sizing by the 75% method. Not sure if that is accurate or not. I attached the diagram and home layout below. I am on...

    How close can pvc and PEX be to boiler flue?

    My understanding is 6” horizontally is required. I have a doubled wall flue so I believe this means it is a type B. Does that mean a pvc vent and PEX can be located more like 3” away? I have read but can't really verify that you can put pipe closer to type B.

    Pex UV System

    Howdy, I just recently installed a uv water sterilizer to my house’s plumbing system. To make the install process faster I transitioned the copper to Pex. It didn’t occur to me while installing it the uv light would shine through the inlet and outlet ports. I went down into the basement this...

The home has 12 radiators - 6 upstairs and 6 downstairs. The boiler is in the basement and the ceiling is now fully exposed, allowing access to riser ends...

    Okay to use Pex B for a new addition?

    I am down to the last part of my room addition; the supply lines. I have always used copper, but my friend has a Pex B crimp tool and I know it would be a huge time saver, plus less time in the crawl space. I currently have 3/4" supply coming into the house that feeds the water heater. Every...

    Replacing Angle Stop

    All of the toilets in my house have PEX stub outs and angle stops like the one pictured. This is a compression fitting- so I should be able to remove the nut and ferrule and not have to cut the pex, correct? Never done this before so looking for any pointers in dealing with this repair.

    Shutoff Valve for CPVC to PEX

    Since I am hearing PEX is the plumbing of choice these days I am thinking of converting some of the CPVC into PEX as I'm in the process of a bath remodel. This is all DIY not professional at all. I need to install shut off valves in crawl space as I am doing the remodel in phases so I won't be...

    Need to replace a valve on a short PEX pipe- any hope to DIY?

    Hello - I found an issue with my water intake valve where there is a drip from the valve when the water is on. It drips from the right most side of the valve where there is a horizontal line/cutout. The valve seems to be one solid piece with no removable parts so I think my only fix for this is...
