The Milwaukee M18 SWITCH TANK 4-gallon backpack water supply features an interchangeable tank design with separate powered base and tank assembly. Designed to provide water for concrete coring and cutting, this battery-powered backpack water tank delivers instant, constant and adjustable pressure from 20 to 60 psi.

The 4-gallon water tank assembly features a dual diaphragm pump, a wide mouth opening for easier pouring and a strainer that filters debris. The backpack frame has wide, comfortable straps and a transport handle. The five-mode pressure control knob adjusts between 20 and 60 PSI, and when paired with an M18 REDLITHIUM XC3.0 battery, the SWITCH TANK can supply up to 12 tanks per charge.

This backpack water supply is made up of two components: the M18 SWITCH TANK powered base and the water supply tank assembly. The powered base includes the motor, battery compartment, and REDLINK electronics, while the interchangeable tank assembly includes the pump, hose and quick connector. Because the pump, hose, and connector is separate, you can add on tank assemblies for different spraying applications, eliminating contamination.

The powered base is also compatible with the SWITCH TANK 4-gallon chemical concrete sprayer (49-16-28CS) tank assemblies.
