I am trying to learn more about the plumbing industry and I have a quick question about expansion tanks.
I understand how they work but my question concerns how the pressure should be set when they are installed. Our water pressure is set at 55 PSI and we have a closed system with a 40 gallon gas water heater. The expansion tank that was installed is a Watts residential tank with a factory preset pressure of 40PSI. It was installed on the cold water side near our shut off valve in the basement...
I have read so many different things about equalizing the pressures vs. having the tank set lower than the house water pressure... I'm confused!
Should the pressure of the expansion tank and the house water pressure be the same? (I don't have the installation instructions...but I trust my Plumber...) I have been on the Watts site, but I haven't found the info I seek.
Should I be concerned about this or am I just creating one more thing to worry about?
Thank you for your patience while I get educated!
