I have a client that has a home that has two electric hot water tanks. One tank does one half of the house, and the other tank does the other half of the house. Recently, she had a plumber install a pressure reducing valve on her house and, (because of what I’ve learned on this great forum) she now has a closed system and she needs an expansion tank. The PRV is set at 60 psi. My question is, do I need to install two expansion tanks, (one for each hot water tank) or could she get away with just one tank on the incoming cold water line, (after the PRV) like by her water softener?
Thanks all,
Mike
