Details
The Milwaukee M18 4-Gallon Water Supply Kit w/ SWITCH TANK (3019-21WS) is a battery-powered, backpack water delivery system built for concrete cutting and coring — no manual pumping required. It ships as a kit with the M18 REDLITHIUM XC4.0 battery, so you can put it to work out of the box. The system splits into two parts: the M18 Powered Base w/ SWITCH TANK (motor, battery compartment, and REDLINK electronics) and the 4-Gallon Water Supply Tank Assembly w/ SWITCH TANK (49-16-19WS), which carries the dual-diaphragm pump, 10 ft hose, and quick-connect coupler.
What it does well
- Delivers instant, constant, and adjustable pressure up to 60 PSI, with a 5-mode regulator knob that dials pressure from 20 to 60 PSI.
- Runs up to 45 tanks of water per charge on the included M18 REDLITHIUM XC4.0 battery.
- OSHA Table 1 compliant when concrete cutting and coring.
- Interchangeable SWITCH TANK design lets you swap tank assemblies — the base is also compatible with the 4-Gallon Sprayer Tank Assembly w/ SWITCH TANK (49-16-19PS) and pesticide sprayer tank assemblies.
Is this the right water supply for you?
This kit is aimed at concrete cutting and coring crews who need a steady, pressurized water feed without dragging a hose to a spigot. If you already run M18, the included XC4.0 battery drops right into your fleet, and the SWITCH TANK base can share duty across water and sprayer tank assemblies. If you only need occasional water and already own M18 batteries, weigh whether a bare setup fits better — this is the battery-included kit.
