In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
I just got into an agency that never had a maintenance program. I have come across a few commercial boilers of varying BTU's that have compression tanks with gauge glasses. Each one is completely filled with water. I'm debating whether I should install airtrol tank fittings and attempt to maintain proper water/air levels or change the tank over to a diaphragm expansion tank. Any insight would be appreciated.
overkill is under rated
