What you’re looking at here is a pinhole leak in a boiler expansion tank. 👀
Expansion tanks help manage pressure as the water in your boiler system heats and cools. Over time, constant temperature changes, pressure, and internal corrosion can weaken the tank and eventually create a small leak like this.
Luckily, this homeowner is a Home Comfort Club member, so we were already there for their seasonal maintenance and caught it early. Since the system was still running, this could have easily gone unnoticed until the leak became worse, caused water damage, or turned into a no-heat situation.
That’s the benefit of regular maintenance: catching the small problems before they become the big ones.
