Our SWITCH TANK™ 4-Gallon Water Supply Tank Assembly is an interchangeable tank powered by the M18™ SWITCH TANK™ Powered Base (not included). The water supply tank assembly includes the pump, 10-foot hose, and quick-connect. The design allows you to add on tank assemblies for different applications, eliminating cross-chemical contamination. It also provides the ability to replace the tank assembly at a lower cost of ownership compared to replacing an entire water supply. The 4-Gallon Water Supply Tank Assembly features a dual diaphragm pump for increased durability and longer pump life. The water supply tank also has a wide mouth opening for easier pouring and a strainer that filters debris from getting into the tank.
