Leak response guide
Treat hot water, steam, gas odors, electrical contact, and rapid water loss as warning signs. Protect people first, then limit damage only if you can do so safely.
Do not touch hot water, steam, wet electrical components, or an energized boiler casing.
Use the normal boiler controls. If water is near electricity or you smell gas, leave the area and contact the appropriate emergency service or utility.
Place a container or towels around a minor drip without removing covers or attempting an internal repair.
Record the pressure reading, where water appears, and whether the leak happens only while heating.
A qualified heating professional can isolate the source and determine whether a seal, valve, pipe, or internal component needs attention.
Continually adding water can hide a serious leak and introduce fresh oxygen that contributes to corrosion.
