    Hi,

    I am hoping someone with more experience than me can tell me what this thing is. it is fitted between the water source to my house from the garage into the rest of the house. It has started to leak at what appears to be a bleed valve (far left of thing). what is barely shown is a valve to turn all water off to the house. I know because i have used it to do repairs on two showers.

    i think this is a check valve but it does not look like a check valve that i am used to. what i want to do is stop the leak. it is slow but annoying. i keep a tub underneath and empty a gallon and a half about every two weeks. it is leaking at the bleed valve (again, not sure that is waht it is). if i just tighten this will i regret it? or should i turn off the water, open that bleed valve, wait for water to drain and fix what might be wrong?

    any hlep is appreciated.

    Looks like a pressure reducer valve that has started to leak. Find the model, get a new one, then replace it. If you use municipal water, call your water company and it is possible they will replace it for you....for free.

    Right on the !! The model number will give you the size and there simple enough to replace. Turn off water at the main water shut off then loosen up the two unions and replace with new washers and tighten up.

    Put a very very thin layer of plumbers’ grease on the mating surfaces of the unions, if their seal is just metal to metal, it helps the pieces come together tighter and more easily.
    And a little on their threads also, it helps the big coupling nut crank down tight with less effort.
    If the new PRV matches the threads and fits exactly like the old one, you won’t have to sweat on new unions.
    But clean off any minerals and junk off the mating surfaces, and under the big coupling nuts.
    Use vinegar or CLR, and gently scrub with a plastic scrubber like a Scotchbrite pad.

    DO NOT use pipe dope or thread sealer to goop up the unions before assembly, they are not designed to need it.
    And it makes taking it apart cleanly a pain in the A$$.

    Thanks all. i will hunt around for a model number with a mirror, probably behind my point of view.
