What is the method to determine the capacity of a relief valve?
The scenario I have is wrong in more than one way, but it raised some questions for me. I have a 1/2" pressure relief valve installed in a bushing that is installed in the 3/4" tap on the top of the tank.
First issue, there is no temperature relief valve.
Second issue is P2803.3 says "shall be installed directly into a tapping"; would you say valve-installed-in-busing-into-a-tapping would be violating this section?
...and finally a question: valve may be installed in a water line close to the tank. So, a 1/2" relief valve could be installed and not violate P2803.3, but it must have an adequate relief rating.
I am looking at Watts specifications, but what is "adequate"? I am thinking that as long as it isn't discharging at static pressure, it should be adequate?
TIA
