I see a 115 PSI water pressure at my home. Looks like my PRV is hosed. I am a complete newbie in plumbing, please take a look at the pictures and help me understand what I need to replace the PRV.
So I believe its a single union PRV. I bought a Zurn nr3xl to replace it. Upper joint seems to be soldered?? Bottom joint can probably be removed turning the union ring. Am I correct? Anything else that I need to know? Please also share what tools I need.
