Forum Title: PRV and Thermal Expansion tank?
I recently purchased a house and the inspectors said I needed to install a Pressure Reducing Valve as the pressure measure at the spigot outside was 80 psi. I've measured it at 78-80 pretty consistently since we moved in. So, I have a few questions: -Is 80 psi high enough to necessitate installing a PRV? -If I install a PRV, do I then need to install a thermal expansion tank on my water heater or are the two not always necessary together? Thanks a lot for the help!

Thanks. I'm learning, albeit very slowly.

I hear 55-60 psi is optimum. I've always had a good PRV installed but never needed an expansion tank.
