What pressure should my boiler expansion tank be?

How do you test a boiler expansion tank?
Once you completely open the valve, you can measure and note the pressure. You can also check your expansion tank’s pre-charge pressure by knocking on the side of the tank with your knuckles to determine if it’s full of air or water. Pre-charge pressure that’s too low may be indicated when the tank is full of water.
What is the difference between a pressure tank and an expansion tank?
The most significant difference between expansion and pressure tanks is their functionality. An expansion tank handles water expansion and provides protection for water valves and heaters. On the other side, the pressure tank lengthens the lifespan of the pump.
Where should an expansion tank be located?
The expansion tank (potable water type) should be installed on the inlet cold-water line. It can be installed anywhere in the building on the cold-water supply (after the regulator). It is usually installed by plumbers on the cold-water inlet of the water heater.
