In 1954, Amtrol invented the first expansion tank to control pressure build-up in closed, hot water systems. Today they are continuing to roll out efficient and reliable tanks to improve your system. The T-12 in-line thermal expansion tank is a perfect example of this. By accepting expanded water caused by thermal expansion, the T-12 is able to then return the water to the system when hot water is used. It also prevents pressure relief valve discharge, dripping faucets, and intermittent toilet fill. From the strong, steel dome to the welded air charge fitting, T-12 is designed to prevent damaging pressure buildup and eliminate energy and water waste.
All T thermal expansion tanks are made in the USA at facilities certified for maintaining high-quality standards.
