We have a Dunkirk Boiler (natural gas) for hot water baseboard heat, combined with a BoilerMate WaterMaker for hot water.

In 2016, we had the expansion tank replaced which sits above the boiler.

Just recently, we've begun to notice some water on the floor. Traced it down to an actual pinhole leak in the expansion tank itself, not in the connecting pipes.


We've put in a call to the guy who did the last replacement, but wonder what we should do in the meantime.

There's nothing to do other than catch the water that leaks and get er fixed.
