Boiler Pressure Problems in Andover, MA

Boiler pressure tells you a lot. Too low and the boiler may lock out or leave the top floor cold. Too high and the relief valve opens to protect the system.

Low pressure usually means water is leaving somewhere. Check under radiators, around valve stems, at the relief valve discharge pipe and on the boiler itself. A sealed system that needs topping up every week has a leak, even if you cannot see it yet.

High pressure is usually a waterlogged expansion tank or a pressure reducing valve letting city water creep in. On a combi boiler, a leaking plate heat exchanger can push domestic water into the heating side.

Reliable Boiler Service connects Andover, MA homeowners with technicians who find the cause instead of bleeding pressure off and leaving. Most residential hot water systems run around 12 to 15 psi cold and stay under 30 psi hot.

Note the gauge reading cold and hot, then call Reliable Boiler Service at (866) 456-6311.

Boiler Pressure Problems FAQs

Frequently asked questions about Boiler Pressure Problems

Questions we hear most often about Boiler Pressure Problems in Andover, MA.

Talk to a real person
What pressure should my boiler run at in Andover, MA?
Most residential hot water boilers sit around 12 to 15 psi when cold and stay under 30 psi when hot. Steam boilers are different and run at a fraction of a pound.
Why is the relief valve on my boiler dripping?
A relief valve that drips or opens near 30 psi usually means a waterlogged expansion tank or a fill valve letting too much water in. Replacing the valve alone rarely fixes it.
Do you handle steam boilers in older buildings?
Yes. Reliable Boiler Service connects owners with technicians who work on one-pipe and two-pipe steam, including air vents, pressuretrols, sight glasses and low-water cutoffs.
What should I do if my boiler is leaking?
Turn the boiler off, close the fill valve if water keeps spreading, and call (866) 456-6311. Note where the water is coming from, since that decides between a repair and a replacement.
How do I know if my boiler is the right size?
A room-by-room heat loss calculation is the only real answer. Boilers that short cycle on mild days are often oversized for the house.
