Boiler Pressure Problems in Temple City, CA
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 Temple City, CA 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.
