The most effective means of controlling water hammer is the installation of an engineered water hammer arrester. An engineered arrester employs a measured, compressible cushion of air or gas which is permanently separated from the water. When a valve closes abruptly, the moving water column is displaced up into the arrester, compressing the permanent air charge until all the momentum of the moving water is safely dissipated, allowing the column to slow down calmly, preventing the development of water hammer.
To control water hammer in most residential applications, install ASSE 1010 Certified AA size water hammer arresters on both the hot and cold supply lines serving washing machines, dishwashers, ice makers and quick-closing tub/shower valves to satisfy the minimum requirements of all model codes.
The 660-GTR1B is a Female Compression Tee MiniRester™ specifically designed for residential applications. It installs either between stub out and supply stop, or between supply stop and supply tube for faucets, dishwashers, toilets or ice makers.
