QUESTION FROM GENE

HOW DO YOU PURGE THE WATER FROM AN AMITRON MODLE 15 EXPANSION TANK. I HAVE BASEBOARD HEATER AND THE WATER IS LEAKING OUT OF THE TOP OF THE EXPANSION TANK. I WANTED TO PURGE IT AS IT SEEMS TO BE OVERFILLED. I CAN NOT FIND A PURGE VALVE ON THE TANK OR NEARBY.

ANSWER FROM HOME-WIZARD

Dear Gene:

Here is a link to a page that describes how to diagnose problems with the expansion tank for a hot water baseboard heating system:

Did you actually mean an "AMTROL" 15 expansion tank? This model expansion tank comes pre-charged from the manufacturer at 12 psi. If you are seeing water leaking out of the top of it, I'm wondering if the piping connection is loose there, and the water that is leaking is coming from your heating system, rather than from the expansion tank itself.

Here is a link to an operating manual for it: http://s3.pexsupply.com/manuals/1249544554380/extrolbroch.pdf

And here is the customer service phone number for Amtrol: 401-884-6300

Hope this is helpful.
