The Therm-X-Span T-12 Thermal Expansion Tank is a pre-pressurized diaphragm expansion tank. The tank is installed on the cold water supply line to the water heater to control pressure build up caused by thermal expansion. Installing the T-12 will virtually eliminate relief valves spills, protect plumbing fixtures and extend the life of your water heater.
Specifications:
Note: Be sure to measure the system water pressure using a water pressure gauge, and make sure that the air pressure in the thermal expansion tank is the same as the system pressure. The thermal expansion tank is pre-charged to 40 psi. Verify the charge of the tank using a tank pressure gauge.
Specifications:
- Diaphragm Material: Butyl Rubber/EPDM
- Factory Pre-Charge: 40 psig
- Max Operating Temperature: 200°F
