Designed to meet user's water supply needs for concrete cutting and coring, the battery-powered water supply delivers instant, constant and adjustable pressure up to 60 psi. The 5-mode pressure adjustment knob adjusts the pressure between 20 psi to 60 psi for ultimate control.

          Milwaukee continues to impress. This switch tank backpack is amazing. I loved the idea of the pump and hose are contained within the tank as to not cross contaminate in the hose or the pump. The main unit provides power and a built in backpack for transporting the tank around. It comes with a 3AH battery which I wasn’t so sure about. This thing never runs out of juice. I bought the pesticide tank sprayer which I highly recommend too. I will be getting the concrete sprayer to seal my driveway, garage and back patio.

          The sprayer and backpack are very high quality. Based on the price and the company name, your expectations will be met. The battery charge lasts several hours of use. The water flow is consistent and strong. These units allow you to swap out tanks with other options such as a chemical sprayer. The backpack is super comfortable and after using it for a month, I have not had any issues with this product. I plan to add an adapter to the water flow so that I can add a sprayer, as I would use that more often.

          Okay, this is a tool that I wish I could give 10 stars & 4 thumbs up. This is also something that is GUARANTEED to solve all pump sprayer frustrations. And how or why this wasn’t introduced years ago boggles-the-mind. I cannot say enough good things about this tool. Battery powered, easy clean up, all great quality materials, very ergonomic, extremely versatile and on and on and on. Of all of the tools that have entered my shop & business (and that’s a lot of tools) this one is by far the most exciting & versatile. This tool is WORTH EVERY PENNY! Thank you Milwaukee & Thank you Home Depot!!

          This Milwaukee backpack water supply kit is ideal for concrete work and many other uses due to the exchangeable tanks. It is battery powered by an 18 volt Lithium-Ion battery and charger. The battery has ample power to run the enclosed pump at six different speeds, and also has an easy on off switch to save battery life. The tank easily removed by releasing two clamps. Come complete with strainer to keep out unwanted debris.The harness is solid, and comfortable to wear, fully adjustable for different persons, very versatile. Well known brand and I would highly recommend it.

          I need a return label so I can send it back. The tank is leaking water. Looks like a bad seam in the mold.

          This is exactly what I needed! I use it on the sprayer base and I can easily go to remote locations and water plants quickly without stringing out a hose from clients house!
