Causes

What Causes Boiler and Burner Water Leaks

Most leaks trace back to a few common causes.

Pressure Problems

Too much system pressure forces water out through the relief valve or weak points. We check and correct the pressure and the expansion tank.

Failed Valves and Fittings

Pressure-relief valves, drain valves, and old fittings wear out and weep. These are usually straightforward repairs.

Corrosion and Cracks

Years of heat and moisture corrode pipes and tanks. A corroded fitting can be replaced; a cracked heat exchanger or tank may mean it is time to discuss replacement.
