Description for Amtrol 141363

With modern plumbing codes mandating backflow prevention, thermal expansion can cause pressure buildup in domestic water systems. When demand is put upon a potable water system, hot water is drawn from the water heater. Cold water from the supply line enters the water heater to replenish it. The cold water is heated to replace the hot water used. With the installation of a backflow preventer, check valve or pressure reducing valve on the supply line, the water heater and the system piping form a closed plumbing system under pressure. As the water is heated, thermal expansion occurs. Pressure increases until the relief valve opens and the expanded water spills from the water heater. This spillage results in wasted energy and a potential safety hazard.

        Comments about THERM-X-SPAN T-12 Expansion Tank (4.4 Gallon Volume):

        The original expansion tank was installed in 8-06. A month ago I noticed water on the floor around the hot water heater. I put a bucket under the T&P valve, and confirmed it was the source of the leak. I replaced the T&P valve but it didn't stop the leak. I checked the pressure in the expansion talk which is installed with the air valve down. when i removed the pressure gauge, water dripped out. I replaced the expansion tank and the leak stopped.

          Q:

          Can the Therm X Span T-12 be mounted horizontally

            A:

            The tank will function in any position, but the manufacturer does not recommend mounting thermal expansion tanks horizontally. If unsupported, the tank could break off the pipe.

          Q:

          What's the difference between this model and the X-TROL version? Do they perform the same?

          • CUSTOMER CARE

            A:

            The only difference is the warranty: Amtrol warrants the Therm-X-Trol for five years and this model for one year.

            A:

            The need for an expansion tank in the domestic water system depends on the local code in your area. Please check with your installer or contact the local water department and they should have this information on the local codes.
