need some info from my fellow inspector on this,
My friend has a boiler in his house from 1950’s
overflow tank, and many shut off valves some within a foot of each other that are very corroded.
there is a TPRV that is blowing every 30 sec. to one min, because of the pressure being so very high.
which in turn is filling a 5 gallon bucket in a half day.
one question is, if the corroded shut off values could be causing the pressure to build up, do to lack of flow through the pipes.
or could there be another reason for the high pressure?
the boiler is not very big, about the size of a 40 gallon water tank,
with an expansion tank of about 10 gallons.
any information in regard to boilers from the 50’s would be great.
