I have PVC plumbing and an outside shower that connects to the hot and cold water lines from the house. There is a brass pressure relief valve that comes off of the shower. This pressure relief valve was dripping so I replaced it. The new one lasted for about 3 months and is dripping again. I don't know any other neighbors that have a pressure relief valve other than the one that is connected to the water heater. Do I actually need this or can I cap it off? I have noticed that if I turn on multiple showers inside the house on at the same time the pipes will occasionly knock. Not sure if that is related to this pressure relief valve or if this is causing more of a problem than a help. Any advice would be appreciated here it
