  1. need suggestions on how to change out the shut-off valve in this picture

    I am going to replace this shut-off valve for the house water supply. As you can see, it goes from PVC, to a (what I think is galvanized) shut-off valve, back to PVC, and then to copper, and that goes into the wall. See picture here: This seems like a bit of a puzzle, because I can't just...
  2. How should conduit terminate at or above drywalled ceiling?

    How should conduit (PVC in this particular case) terminate at or above a drywalled ceiling? Specific case is a surface-mounted subpanel in an attached garage. Would it just be a hole in the ceiling drywall, through which the conduit passes and then simply ends with the wire coming out?

  5. Conduit Wire

    When installing wire in a short section of pvc conduit above ground (like to an outside sub-panel with UF wire) is it permissible to strip the wire's sheathing back the same length as the conduit and then install it? Or is this not advisable since the ground wire would be exposed/unprotected...

  7. Water Heater - Condensate & Vent Pitch Issues

    Hello, I'll try to keep this as short and straight forward as possible. This past winter, after many years of working perfectly, my Bradford White 40gal Gas Water Heater began to short cycle and would rarely satisfy the thermostat when called upon. I researched the issue exhaustively, did...

  13. Pressure testing a drain and can't find leak to save our lives

    We're renovating a 100-year-old house and have replaced nearly all the old drains with PVC. The city requires an air test of the drain system -- it has to hold 5 psi for 15 minutes. We keep having a slow leak. We've soaped everything several times over. Found leaks some times, didn't others...
  14. How to hang PVC pipe for reduced noise?

    I am in the process of replacing a section of bad cast iron with PVC pipe. The 4" pipe will be hanged vertically and there's about 8 feet of it, with a turn in the middle. I've read PVC is louder than cast iron and sometimes it can happen that the weight of the water as it flows through the...

    I am a homeowner (not a plumber) so I apologize in advance if I use any wrong terminology. I have had a recurring issue for years with tree roots getting into my sewer line. The line is PVC but a thin PVC. Last night the roots clogged the pipes again. Today I hired a new plumber (seems...
  16. Exterior Conduit - Best Option

The unit will be moved from the south-east side of the house to the middle of the south side of the house.

    I'm renovating the bathroom and need some advice on reconfiguring the waste pipes at the point in the picture. The simplest solution I can see is cutting off the trap and capping the shower waste pipe, then tying the new toilet into the 3" pipe. Despite lacking elegance, is this an acceptable...

    I have a 6-way PVC tee on the main drain/sewer stack in my home. It's a 3"x3"x3"x3"x2"x2" tee. About 8 or 9 years ago the shower drain came loose from the shower basin. When trying to glue the pipe and reattach it to the shower basin, the collar on the main stack where the other end of the...

    Harry the homeowner here. My town lets me pull a permit for electrical work (no panels!) but I'm an amateur. However, doing surface mount with 1/2" schedule 40 pvc is within my capability. Question -- why can't I find an "inside corner pull elbow" in pvc? These beasts exist in EMT, but...
