Where Is the Water Coming From?
Without opening the boiler, look at whether the moisture appears to come from underneath the appliance, nearby pipe connections or another visible part of the heating system.
Can a Leak Cause Low Pressure?
Yes. Water escaping from a sealed heating system can gradually reduce system pressure.
If the pressure continually falls, read our guide to a boiler losing pressure.
Can High Pressure Cause Water Discharge?
Pressure-related faults can sometimes lead to water being discharged from the system. If the pressure rises excessively when heating, see boiler pressure too high.
Should You Keep Using a Leaking Boiler?
A small leak can worsen and water can affect electrical and mechanical components. Arrange diagnosis rather than allowing the problem to continue.
Will the Boiler Need Replacing?
Not necessarily. Many leaks are repairable. Replacement decisions should consider the failed component, boiler age, overall condition, parts availability and repair cost.
For older appliances, see repair or replace a boiler.
