If you find a water pressure regulator on the property, do you automatically call for an expansion tank at the water heater if one is not present?
In all the states where I’ve worked in real estate, I’ve only found one expansion tank on a water heater, and that was here in San Diego back in 2002 or so.
I recently met a home inspector in Washington who always calls for an expansion tank if one is not present and there is a pressure regulator on the property.
Haven’t heard of this requirement before and cannot find such a requirement in any of my books at the moment.
Thanks for the guidance.
I’ll also try to check with some plumbers here later today.
