Plumbing: Any Issues with Watts 2M2 Duo-Close Shutoff Valve?

D107 Member Posts: 1,849
As part of other plumbing work we're doing in the house we're replacing the old H/C gate valves for the washer. The Watts unit was recommended (also something about a DWB+ additional piece) and I wanted to know if there might be any cavitation or cross connection issues. (I believe I saw on the Wall that if the unit is kept in off position when not in use there is less likelihood of any problems.)

    All the ones we have installed did not work. We removed them all.

    good to know

    and when you think about it, what's so hard about turning two good ball valves on and off before and after doing a laundry?

    watts valve

    david, i've seen 100's and have installed at least 30 of these single lever washing machine valves.their design is 1 lever closes 2 valves. they cannot cause a cross connection by design.if it happens, its the solenoid valve in the machine, and as bob said, a couple of check valves are in your future. btw, i did recently have to replace one. probably 20 yrs old,weeping at the stem.all it really needed was a couple new o-rings, but try finding the right o-ring. easier to change valve. rob

    I have had...

    a number leak right out of the box....I won't use them any more. I prefer the two ball ball boiler drains or the ball valve type laundry box....kpc

    Watts duo close WM valve

    I have also installed at least 30 of these vlves and have never had a problem. And if they do leak, there is a rebuild kit so you don't need to replace the whole valve. Are you greasing the o-rings and tightening the screws?

    Are you talking about the Intelliflow automatic WM valve?

    I've had problems with them in the past.

    Ditto to

    the no problem guys. I've installed at least 100 and repaired maybe a half dozen after years of use and replaced a few as well.

    I am on my second at my home in 32 years with the one now in place being installed over 15 years ago.

    The valve can not cause a cross connection but could let one occur if left on. We learned from a friends tragedy, who had over twenty five thousand dollars in water damage from leaving her two valves on all the time, to always shut it off when not in use.

    We won't even leave the house for a short trip without turning the washer and the valve off.

    They are a good product but like anything you can get a bad one and if Murphy strikes more than one but highly unlikely.
