I heard a click, click, click sound coming from the Basement. Went down to check it out. Boiler is heating up the cast iron radiators fine, but when I went in the basement , I heard the clicking sound. Then, it sounded like the gas was shutting down . 5 seconds later , I heard a wump sound as the boiler fired back up..
Anyone know what might be causing that?
I had the Aquastat and a new pressure tank installed about 2 years ago. It was running fine until today.
