PVC Ball Valves

Earthfire Member Posts: 543
Schedule 40 plastic valves never seem to hold up for me. the handles come of or they leak or some other problem . I started using Schedule 80 union ball valves exclusively . Haven't had any of usual problems since. a little pricier but a lot fewer headaches,and no cutting out and regluing plastic lines

    better ball valves

    We have a range of greenhouses with 1-1/4 inch PVC irrigation lines.
    We have been using 1.25 inch Schedule 40 PVC lines with PVC ball valves.
    We have over 400 ball valves to control our irrigation.
    The ball valve has not held up. The valve wares out and we are constantly replacing them.

    Could you suggest an alternative valve that is economical and that will give us better service?

    replacing them with threaded brass valves.
    You will have to add m. adapters and maybe a pvc union
    to get them in.... and be very carefull to get them tight...
    this will work well for cold water only.... hopefully you aren't
    using regular pvc for hot water anyway.
    Teflon tape AND a teflon based dope together seem to be the best
    way to insure that pvc to brass doesn't leak.

    Ball valves

    often times get sticky to turn after a lot of hard water service. I have used Floyds method, but be sure to fasten the valve solidly or you risk breaking the threaded portion of the PVC male adapter when they get stiff to turn.

    Maybe a wheel handled gate valve would be better. I have 20 new 1-1/4" plastic gate valves. Yours for 50 bucks including shipping :)

    PVC gate valves

    I have some installed in about the most hostile location I can imagine--coming out of the ground on a slope. They are the drains for my lawn irrigation system (no annual compressed air blowout here). A quote from my grandpa's old set of "handyman" books certainly applies, "Lucky is the man with a rear-sloping lot."

    They are operated very infrequently, once or twice per year, tend to get covered over with dirt/grass, hit by the little spade when uncovering them, and I've had zero problems in five seasons.

    In leiu

    of mip adapters does a schedual 80 threaded nipple have more strength in it and then a coupling? One nipple equals two mip adapters. and two couplings, cost cannot be to much more out of line. just thinking bigugh

    in regard to Materials.....a point fot the old school! However, if any decent valve is "exercised on a regular basis, it's life and performannce will be gtreatly extended Mad Dog

  • i had almost read that wrong

    but i agree exercising keeps them in shape for when needed the most, and also exercise yo main house and sub-panel "breakers" so they will last longer (lurned that the hard way)

    That's why I like fuses better

    No matter how old they are they will still blow when necessary. Wonder how many people have gotten killed by breakers not working properly? I've seen them not work and apparently you have too...pretty scary stuff!

    You WILL Get What You Pay For!!

    Please don't even consider PVC valves...use American made brass valves.

    Those replacement FED-PAC breakers ain't cheap.You can buy a GE 100amp panel for the price of one of them breakers. Zinsco is another one of the obsolete wonders out there. We use SquareD QO panels or Cutler-Hammer as second choice
