Thanks for all the help in the last few weeks.
Hopefully one last question.
1992 house, no expansion tank off the hot water heater. The house does have a pressure regulating valve, but no backflow that I can find (I think the PRV acts as one?). I am installing a new water heater, should I install an expansion tank even though the house has never had one, and never had any water come out of the check valve in the previous heater? I am using PEX, how do I support the tank with plastic plumbing (it will be on a wall in the garage)?
Thanks,
--Brian
