Boiler Leaking Water

When this becomes an emergency

• Water is spreading across the utility room floor under the boiler.
• The gauge needle sits higher than its usual mark and keeps drifting up.
• The relief valve weeps continuously rather than venting once and stopping.
• Green or white crust has formed on the fittings above the wet spot.

What a pro does

Water under a boiler seldom means the vessel itself has given out. In propane-fired systems on rural service roads, the source is usually a tired relief valve, a circulator seal that has begun to weep, or a threaded fitting corroded from the inside, and a technician follows the wet trail back uphill to the real origin rather than swapping parts on a hunch. Altitude changes the picture too, since a system filled and pressurized at high elevation carries different numbers than the same boiler would near sea level. Killing power and closing the feed valve is the sane holding move until someone's had a look.
