I have a Watts single handle washing machine valve that was installed by a plumber less than 5 1/2 years ago, and I only did the laundry once a week or sometimes not for 2 or 3 weeks. Tonight it developed a leak when doing the laundry. The leak was at the stem (handle). I went to Home Depot and bought a new Watts valve for $29 and just replaced the whole thing (including the O rings) except that I reused the old elbow attachments since those were soldered on.
The new valve appears to work fine, so far, and I am keeping fingers crossed that it stays leak-free.
My question is this: When doing the laundry I would typically leave the valve half-way (or less) between Off and On rather than all the way On. When not doing the laundry the valve was off. Do you think the new valve would be less likely to develop a leak if I turn it all the way On rather than half-way-on (or less) on when doing the laundry?
(I now have a pressure-reducing valve where the water comes into the house, so maybe I don't need to bother with the midway position as a means of reducing the water flow)
Thanks,
Jay
