Thanks Harold, as I mentioned there is an expansion tank mounted that indicates that it was filled at the factory at 12 PSI.
It also says not to let the air out of it.
When I was refilling the system I did let the air out by pressing the little puge valve nipple.
Should I refill the expansion tank to 12 PSI now or it doent matter.
Thanks again.
