Hey Guys,
I have a Burnham boiler with a Weil McClain indirect WH tank attached to it. I've noticed recently that water has been leaking from the PRV of the boiler and have seen PSI at around 35 at the high point. I've gone through the usual steps:
1) I turned of the boiler and let the pressure hit 0. I read the expansion tank pressure and it was good, at around 12.
2) I reduced the pressure to around 10 and shut off the cold water main to the auto feed valve. Pressure slowly rose over the next few hours
3) I reduced the pressure to around 10 and shut off the cold water main to the indirect tank. Pressure slowly rose over the next few hours.
4) Aquastat is set at 183. I have though seen it reach 220.
Any idea what is wrong? Did I properly isolate the indirect tank and is my conclusion on that point valid?
Thanks,
Russ
