Where do you put the expansion tank on a boiler?

Your expansion tank can be anywhere on your plumbing system and does not need to be installed in close proximity to the water heater. It is most commonly installed using a “T” at the cold inlet to the water heater. But, functionally, it can be installed anywhere on the cold inlet line.

Can I install an expansion tank myself?

When putting an expansion in an abnormal position (specifically sideways or horizontally), make sure to support the tank.

Does expansion tank go on supply or return?

The expansion tank is installed on the supply-side of the boiler system. Its sealed-in air pre-charge prevents water from entering the tank until the system pressure begins to rise. Water is expelled from the expansion tank, back into the heating system.

What pressure should my expansion tank be?

between 50 and 60 PSI
The recommended water pressure is between 50 and 60 PSI. Thermal Expansion Tanks contain an air bladder which is pressurized with air, and expands and contracts to absorb the expanded water from the water heater. needed. Check the air pressure in the Expansion Tank using a tire gauge.

Is it code to have an expansion tank on water heater?

The California Plumbing Code (Section 608.3) and the California Mechanical Code (Section 1005.0) requires a thermal expansion tank, or listed equivalent, to be installed to water heating systems to relieve excessive building pressure during the heating process.
