    Default Leaking shut off valve

    I turned off the shut off valve to my refrigirator ice maker for repair. When I turned the valve on again it began leaking, so I turned it off again. How do I stop the leaking? Is it just a matter of taking off the nut and repaking it?

    The packing around the valve stem tends to get hard and conform to the stem. When you move it, it retains that shape and doesn't mold itself to the new location on the stem. Before trying to replace or repack anything, try just tightening the stem nut slightly and see how that goes. Also, when you turn the water on, turn it on full, then back closed an 1/8th turn so that the packing isn't being deformed by the valve itself.

    If you do end up replacing or repacking the valve, be sure to turn off the water main and relieve the pressure in the line by opening an exterior hose bib before messing with the valve. It will likely be faster and easier to just replace the valve rather than trying to repack it.

    Thanks for the information. If I replace the valve I need to remove the old valve at the two areas that it is soldered on to the copper pipe. Is there a way that I don't need to use solder to connect the valve, that is using compression fittings?

    Can you post a picture of the valve in question? It would seem odd that you'd have to break any solder connections to change the valve. Typically, angle stops are either compression or threaded, they do not require solder work of any kind.

    its been my experience that most of these valves are soldered,at least here in MA.compression fittings on the "live" side of a shut off are illegal as well they should be,if you cant solder a joint your in the wrong trade,repacking this valve is a slam dunk repair

    Interesting. I've lived all along the western coast my entire life and have never come across a soldered angle stop. My guess is that it's either a recent code change or a regional preference.

    That's what makes this trade fun, learning what's done around the country/world and how it differs from your own backyard.

    So you are saying that you can not use a 5/8x3/8 compression stop
    on a stub out?

    In my experience repacking a valve is easier than replacing a valve whether it's sweated on or some type of compressinn fitting.
    Get the old packing out with a screwdriver. It's usually packed hard at this point.
    Use the right packing, usually thin graphite or teflon. Not usually rope packing. It's usually harder to work with, especially on smaller valves.

    thats correct,no 5/8 compression on the stub out,this rule has been around for at least a decade,just because the box stores sell them dont make em legal,not that i dont see them being used but its usually a home owner that isnt comfy soldering,not a union thing either,im not but still take pride in what i do
