Good luck. I had to replace my washing machine cutoff values a couple of months ago. It was a 30 year old gate value and though there must be many homes in my town with the same builder's grade shutoffs I was not able to find properly sized washers at Lowes, HD, or the plumbing supply store. Sweating vertical pipes that are/were filled with water is not fun.My washing machine cold water ball valve is leaking. It's designed to either be sweated or screwed into a shark bite fitting. And it's behind sheet rock. I'll get around to it in a few more days--since we've moved elsewhere.
