Rough plumbing manufacturer, Sioux Chief offers a new Expansion Tank Support Kit. The Expansion Tank Support Kit is an engineered product that comprises a simple, strong, steel bracket that secures expansion tanks. The 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 10 to a case, in two sizes: Kit 598-0210 has a 32.5 inch stainless steel snap-lock band to secure typical 2-gallon tanks. Kit 598-0213 has a 45-inch stainless steel snap-lock band long enough 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.
