QUESTION:Towards the tail-end of the heating season (which I'm not entirely convinced
is over here in Ohio, based on the cool, grey and rainy weekends recently),
I noticed the pressure in my Crown Aruba boiler was reading lower than the
normal 15-18 psi, at around 8psi. After I shut the boiler down and allowed
the system to cool, I checked the air pressure in the Amtrol (Fill-Trol
model 109) expansion tank with a digital pressure gauge and it read only
3.5psi.
Can these things leak?
I replaced it only a coupla years ago, though I never bothered to see if the
'factory fill' of 12psi was actually there. Any reason why I can't 'pump it
up' slowly back to 12 psi and see what happens?
ANSWER: boiler system = not a playground. if you read all the manuals on the
collection of all devices which make up your system, it will show the
range of capacities and adjustments.but it's best to have an hvac man
visit to give you the adjustments and info for your labeling of each
pipe and wire and valve and the step-by-step for your annual checklist.
