The Sioux Chief Expansion Tank Support System is designed to secure expansion tanks to wall studs and is ideal for typical apartment installations where the water heater is installed in a closet.
Expansion tank kits are sold in two sizes to secure typical 2-gallon tanks and to wrap around 5-gallon tanks. Each band threads through a 16-gauge galvanized steel bracket that fastens to the stud wall with two 2-inch screws.
