Greetings all
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?
Thanks in advance...
