Thanks,Jim. You seem to be working as hard in retirement as when
you worked full time. After figuring out that the auto feed was
also the water pressure valve(doh!), I shut it off and released the
pressure in the boiler using the relief valve. Now operating at
20psi. The old valve was a conbraco 35-503, and I see replacements
for it labeled 35-503-01 for $66. It looks like a pretty straightforward replacement job;anything I should be wary of?
