Therm-X-Span T-12 Thermal Expansion Tank 4.4 gal

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:

• Diaphragm Material: Butyl Rubber/EPDM
• Factory Pre-Charge: 40 psig
• Max Operating Temperature: 200°F
• Max Working Pressure: 150 psig
• System Connection: 3/4" NPTM Brass

Install the expansion tank on the cold water supply line to the water heater at a point between the water heater and backflow preventer or other one-way device.

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.
