can a extrol tank increase in air pressure by itself on system or would someone have to pump air in? i have from time to time found more than 12 psi in tanks when dropping system to 0 psi to check and had to lower them on single or two story homes.

    They may have been

    over-charged at the factory and the original installer did not check for proper pressure.

    I like

    I like an isolation valve between the expansion tank and the system and a boiler drain between the expansion tank and the isolation valve. You don't want any water pressure on the tanks bladder to influence the air pressure.
