As an alternative to an expansion tank the Watts 80 is recommended for pressure relief when connected to a closed system (county or city water). Anyone use one? Do they work and how reliable are they? Thank you.
It can be installed anywhere on the cold supply side after the PRV.
PRV? Pressure Regulating Valve?
I see your points, all of them... I'm looking at an Amtrol ST-5 2 gallon, looks good because I really wanted a lined tank, for corrosion reasons. If anyone knows of a better one, Please let me know.
It did say to install it on the cold. That is the normal way. It did not say it was only suitable for the cold IMO. It said it was good to 200F working temperature.The instructions specifically say to install it on the cold water line, NOT THE HOT!

This is awkward, but...
