Worked great, used my existing unions and it still fit....
Worked great, used my existing unions and it still fit. (Same brand of course). Only giving Good rating because shipping was far longer than expected. If my old one had had a leak instead, it would have been a very long time with no water.Symptoms: My water heater temp/pressure valve was spraying hot water out maybe a few times a day. I had also noticed maybe 3 years ago that my water pressure increased a lot, causing loud flow sound in the house pipes. I tested at about 95PSI. But was loving it, so didn't think to consider something was bad in the system. After putting this new one in, I turned it up to 75PSI (It's max) and tested that to be relatively accurate. No problems since, maybe 1 month later so far.

Good Product, super fast delivery
This is a pretty standard water pressure regulator that looks identical to the old one which was probably 20 years old (just a guess). It seems to be good quality, came with everything needed for installation and was delivered much more quickly than I expected. No complaints at all here.
