This morning I heard water running when it shouldn't have been. I went down to the basement and the relief valve on connected to the bladder tank had tripped, and water was flowing out of the valve. My question is, once these valves release, do they have to be replaced? Also, when they go (this one is about 25 years old), do they always go because of excessive pressure (which means I have other problems), or do they sometimes just get tired, and pop? I have to start troubleshooting, so I thought that I could block the outlet from the valve, then see if everything else was still working correctly. Naturally, I will have to make sure that I don't let the pressure get too high, or something will really pop! Does this temporary block sound like a good idea? I just want to make one trip to the hardware store.
