What to do with stuck PRVs on clean and checks
Hello, I'm a service tech and the company I work for now wants us to drain steel expansion tanks on every clean and check. Im not keen on this for the reason that 1 90% of the tanks don't have airtrols and take forever to drain, 50% don't have isolation valves, and basically every PRV gets stuck open when you try to re feed water into the system.
If I had it my way I would have bypasses pipes around the PRV on every system as well as airtrols but as you know you have to work with what you got.
So what would you do? It's not fair to the customer to make them replace the PRV that is never going to be used unless there is an issue and at that point it probably won't work anyways.
