When arrived, the pressure in the boiler was at 20 psi. The customer mentioned that when the boiler is on, water starts coming out of the pressure relief valve. Found the Extrol (expansion) tank is full, and the circulator pump is making noise. When the pump is on, it is not spinning at full speed to push the water to the 2nd fl. The Extrol tank and circulator pump need to be replaced. The Extrol tank needs to be moved to a different location, due to the tank is currently upside down and not accessible.
