Don't ignore a boiler leak — it worsens over time
Frequently Asked Questions
Why is water dripping from my boiler's pressure relief valve?
A relief valve that weeps or drips usually indicates system pressure is running too high, or the valve itself is failing. Both need professional attention — don't ignore a dripping relief valve.
Is a boiler leak dangerous?
It can indicate a serious safety or equipment issue. A cracked heat exchanger on a gas or oil boiler can allow combustion gases to enter the water or structure. Have it diagnosed promptly.
Can I fix a boiler leak myself?
Tightening a loose fitting is fine for an experienced homeowner. However, most boiler leaks require professional diagnosis to find the root cause and ensure it's properly repaired.
What's the cost of boiler leak repair?
Cost depends on the leak source, equipment condition, access, required parts, water damage, and whether a failed heat exchanger or pressure problem changes the scope. Diagnosis supports a project-specific estimate.
