Review: worked as expected. (careful of vacuum when unscrewing) - Worked as expected. The original's rubber had been dissolved and torn, presumably by years of the chlorine in the water. Note: unscrewing the chrome top of the valve may be very tough and it'll seem stuck, even with a strap wrench because it's just water under there and thus a vaccum prevents the top from moving up. now that i think about it probably should leave the water source on at least a little while unscrewing to not deal with it. or initiate a flush while the water is still somewhat on and then immediately turn it off. Not going to experiment on it now, but yeah it's probably THAT and not that it's corroded together. Don't just keep cranking on it or you may pull the pipes out of the wall.
Review: Nice Quality - Nice quality and just the right replacement part. Installed it today and took care of the problem.
