I was thinking about installing an expansion tank on the water line in my house and would like to pose a question. I want to do it to protect my system fromthe risk of water pressure surges coming from the public service, and from the possibility of pressure building up from the water level dropping in my water heater. Should I put the expansion tank on the water main coming into the house or on the hot water line right after the water heater? I have a backflow preventer in my water heater.
Thanks!
