Boiler Circulation Pump Replacement

Call us if you notice any of these:

• The boiler is hot but the radiators stay cold and there is no hot water at the faucets
• Loud buzzing or rattling noises, which can mean trapped air or worn bearings
• Pools of water beneath the pump, a sign the flanges, joints, or pump body have failed
• Radiators taking much longer than usual to warm up
• Higher energy bills and poor overall heating performance

A circulator can fail from damaged valves, worn bearings, trapped air, or excessive pressure that loosens the flanges and causes leaks. Some noise issues can be eased by bleeding trapped air, but a leaking or seized pump needs replacing.

Because the pump is such a critical component, we recommend regular checks as part of a yearly boiler tune-up, and a professional replacement rather than a home repair, since the system is pressurized and the work affects the whole heating loop.

A standard circulator pump replacement typically takes one to two hours, depending on how accessible the unit is and the condition of the surrounding valves and connections. Cost varies with the pump model and labor; as a general guide, a typical replacement runs about $350 to $750, with specialty pumps or emergency service costing more.
