I use it at least twice a month to upkeep my yard, spray for bugs, kill grass, spray sealer on concrete and patio brick,and many other numerous projects. This will be the last sprayer you need to buy, as long as you take care of it! After using it for whatever I am doing, I wash it out thoroughly with clear water. It’s impossible for it to leak down your back and onto the back of your legs since all the parts are internal to the tank. You can purchase all the viton seals and spray wand seal, along with the strainer that is in the spray wand handleon desertcart for a very reasonable price. I have never had to purchase any new seals yet. I have taken it apart a couple times to put Vaseline on the seals to keep them moving easily. Buy with confidence! By the way, this is the hand pump backpack sprayer. No need to be purchasing batteries every couple years, or worry about charging them. I have not put one cent into this sprayer after purchasing it in 2020, and it still works perfect perfectly.

Here is a list of the Field King MAX 190348 upgrades: 1) 21" stainless steel wand with chemical resistant poly lining. 2) Deluxe padded harness with back pad and lumbar support, adjustable shoulder straps, waist belt and chest cinch strap. This backpack harness ensures all-day comfort while you work. 3) Fold away pump handle for easy storage. Both backpack sprayers are equipped with the internal, No Leak Pump which prevents liquids from leaking down your back. The internal pressure chamber can reach up to 150 PSI allowing a straight stream to reach 30 feet (dependent on the chemical being sprayed). Also they both have Viton seals for resistance to harsh chemicals and dual filtration to prevent clogging.

Thank you for your interest in our products. **Q: does this have a built it agitator and can wettable powders be used in it** A: No agitation. It’s a manual backpack. **Q: So i have a pest control company and i was looking to add a back pack - any pco out there using this or i am open to other suggestions??** A: HI, This unit is ideal for use with cleaning solutions, disinfectants, stains, sealants, fertilizers, herbicides, and fungicides to help beautify your outdoor areas. I don't see anything saying that it can't be used for pest control. Thanks! **Q: does this version also come with the 25psi regulator?** A: It has a pressure regulator, but I think of it more as a no drip regulator that prevents the the spray that remains in the wand from dripping if the pressure gets below 25 psi. It also ensures a clean spray pattern as most nozzles don't do a good job of dispersing the spray below that pressure. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Don’t waste your money on anything else! *by M***L on 27 July 2026* I originally bought this sprayer in 2020.
