    Default These aren't shutoff valves! what are they?

    I went under the sink to turn off the water supply and found these plastic-like connections that have a disk that I thought might be the shutoff but they just seem to freewheel forever. does anyone know what they are?

    Yeah, they're shut off valves, el cheapo ones. You have to either pull or push the disk (in or out, I forget which) to shut them off or turn them on.

    REALLY? WOW I have never seen any like this! I guess I will try pulling first LOL. Thank you so much for your response Furd. You learn something new every day, especially when you buy a new house!

    If you get up real close it is spelled out on the disk to push or pull. I didn't know myself until about a month ago when my sister bought a new (to her) house and it has those funky valves only hers have the hose permanently fastened.

    Your real fun will come when you have to replace those valves since they slide on easily, but do NOT like to slide off. I cannot imagine putting a metal compression nut on a plastic valve the way those seem to be assembled. I remove and replace a lot of those valves, but have NEVER installed one, nor would I.

    Should be written on the disk, but they pull to close.

    Best thing to do with them is to cut the off and put on some 1/4 turn metal valves.

    You've got plenty of pipe sticking out, but to get any new valve to fit, you'll have to clean the paint off. I think I'd just cut them off, sand the pain off, and install some new ones, either compression, or solder on. Solder may be required if the pipe ends up scratched up, but if you're careful, a compression valve should seal fine.

    Those are push-pull shutoffs.
    I'm so used to turning valves, so those give me a momentary pause.
    My daughters home had those.
