I have a electric water heater that has a blue 2 gal expansion tank installed vertically on top of the water heater. I believe its connected to cold water line.
It is rusted on the bottom and has sprung a steady leak via some pin sized holes.
So, I purchased a new tank from Lowes for $50 but need help with install.
Can I simply turn off water heater, turn off water supply, then unscrew old one and screw on new one? or, are there additional steps?
The tank is pre-charged to 25 PSI - do i need to change this to match my water heater pressure? how do i measure this and where ?
