Thread: Plastic Push Pull Valve

  1. #1

    Default Plastic Push Pull Valve

    I have a plastic push pull valve under my bathroom sink that is leaking. This valve is connected to copper piping . I want to replace this valve with a metal quarter turn valve but don't know how to get these plastic values off. The value is too close to the wall to cut off and start over. Can anyone tell me how these are attached to the copper pipe and how to remove them.
    I was planning on relacing it with a compression fitting but don't know what I will find if I can get the old one off.

    Thanks for any help you can provided.

    If it is what I think it is you will have to turn off the water, drain down the house and carefully cut it off the pipe.

    Is the house piping copper or CPVC?

    Copper. Will the pipe be in a condition where I can put a compression value on the copper pipe?

    If you're careful when you cut it, yes. It has to be damn near perfectly round.

    How are the plastic valves attached to the copper pipe?

    Default valve

    They are slid onto the pipe. Sometimes you can remove them by twisting them while pulling. Other times you have to tear them apart so you can get to the barbed ring holding onto the pipe. You do not have to cut the pipe off.

    Default push pull valve connection

    2 questions:

    1. Does a push pull valve like the photo shown , connected by a compression fitting or glued?.

    2. I have not seen the (mechanics) inside of this type of valve - so
    when the valve is not fully push in or pulled out is there a possibility of a slight dripping leak ?

    Default valve

    IT is neither compression or glued. It slides on and a toothed ring grabs the pipe. You can pull it while turning it to remove it.

    I grab them with vice grips and break the plastic untill I get down to the innards and the ss grabber ring. Then I twist the ring off, buff up the pipe and either swett on a new valve or use a comperssion stop.

    I can't believe those are code approved, anywhere.


    Some things are just better, gone.

    Except for the bad smells, soot stains, and dripping burning plastic...
