Can someone help me with a gas fired boiler. I have an old American
boiler that has developed a problem with tank pessure
exceeding 30 psi. which
blows the 25 psi pop off valve. And then
returns to 10 - 15 psi for hours at a
time and then out of the blue it
builds to much preesure and the safety valve
goes off? Coincidence or
not this problem started immediately after a "free"
inspection? I have
so far replaced the pop off valve and the water pressure
valve. I also notice my Aquastat was set to maximum temp of 200
degrees. Other than the pressure the boiler is working fine. Does
Be 100% certain that *no* water is being fed to
the boiler, even via a bypass/manual fill valve.
One good tipoff is if the feed pipe feels cool.
If no water is being fed, the pressure should not go up
dramatically, UNLESS the expansion tank is waterlogged.
If it's a diaphragm tank, it may have failed internally.
I should have added that control failures might cause
high pressure. For example, if the circ pump(s) quit
running and/or the aquastat stuck closed, the boiler
could fire continuously and it would wind up steaming
till the relief went.
Thanks Jim for the advice. I can tell you the boiler does not fire
constantly. The circ pump seems to be running fine. I put a gauge on
the expansion tank valve and got 0 psi? I tried to put air in the tank
and it wouldn't take it. is there some kind of "special" adapter for
this? I put my tire chuck on there with 160 psi from my air compressor
and I couldn't get it take any air?
I am looking for a top freezer refrigerator with the maximum capacity
for the refrigerator at the lowest cost. I don't need any of the
bells-and-whistles which seem to come, inevitably, with the larger
sized, better quality refrigerators. The largest refrigerator I would
find with the conventional top freezer style is the GE Profile Arctica
refrigerator with a capacity of 24.6 Cu. Ft.
It is model number: PTS25LHSWW. However, in reading posts to this
group about GE refrigerators I have seen a lot of criticism of the
quality of GE products. Does anyone know anything about this model?
Or are all GE refrigerators of poor quality these days? And if so,
what company, if any, has well made refrigerators? Thank you for your
Don't know much about top-freezer models. We just bought a GE Profile
side-by-side to replace a _6 year old_ Amana that died on Thanksgiving
day, compressor. I'm kinda down on Amanas right now. Prior to the
compressor failure, we had lost the auger motor, and we were on the 4th
icemaker unit. Meanwhile the 20-some year old GE in the garage just
keeps chugging along, one of the reasons we decided to go with a GE to
replace the Amana.
