I am putting in some new plumbing, and I have to put an expansion tank in. My questions are do I need one for my hot water tank, and the main water supply, or just my main water supply? Where do I mount it, right after the water meter? If I need one for the hot water tank as well, do I mount it on the hot side of the tank, or on the cold inlet? I believe the correct way to mount it is vertical, and just with a tee off of the main line? Do they come with air in them, or do I need to put air into it? Thank you for your help.
