    PEX connections in an old house

    We had our kitchen remodeled in our 1920s house a few years ago. As part of the remodel there was a copper pipe in a drop ceiling which was cut and fit through the ceiling joists. PEX pipe was used in the process to raise the pipe. I was not familiar with PEX until the plumber was done with the...

    Why isn't PEX the same size as copper?

    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...

    New build; seeking advice on plumbing design; floor plans attached

    I'm in the design stage of a new home in the Phoenix, AZ area (slab, 2 stories, Eljen septic).

    Quote Sanity Check

    We just purchased a home with PB piping and was planning to re-pipe the entire house. I was planning to attempt to re-pipe the house myself but decided against it since we've got several other projects going at the same time. We got three quotes for replacing with CPVC; two included patching...

    PEX okay for underground irrigation system?

    I'm a DIYer and have a sod delivery arriving Monday for my small suburban yard (2500 S.F.). Last minute it occurred to me that a simple irrigation system with 3-4 heads would be a god send, so ideally need to get something in the ground this weekend. I'm looking at the Orbit system, which takes...

    Replacing Copper Water Supply Line with PEX?

    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...

    Change Kitchen to Softened on PEX

    New construction. Plumber put kitchen sink and icemaker on unsoftened. We'd like the softened just as a matter of preference. He wants $60 to change them to the softened lines on the PEX block. Is this something I can do myself by just shutting off the water to those lines, using a wrench to...

    PEX Under Outdoor Deck

    Can I run this PEX from my basement, outside, under my deck, to a hose bib? Does it need to be run in conduit, to protect from sunlight, even though it is under my deck? Are there any issues with contact to pool water? Is a backflow preventer and/or a vaccuum breaker needed? I understand that I...
