Item Information

The Roundup 190327 Backpack Sprayers does the work of a piston or diaphragm backpack sprayer. The exclusive internal No Leak Pump keeps your back and clothing dry. The paddles keep liquids, powders, and water-soluble solutions mixed, in solution, and ready to spray. Also the pump features Viton seals that can be easily changed within minutes without tools (up to 7x faster than the leading competitor). The premium shut-off offers a comfort grip, lockable trigger to prevent hand fatigue, and a removable in-line filter to reduce clogging. The Roundup 190327 Backpack Sprayer is capable of spraying up to 150 PSI for those hard-to-reach areas. The included pressure regulator maintains a low, continuous 25 PSI (great for spraying herbicides and weed killers). The foldable pump handle reverses for left- or right-handed use, and the tank has a built-in carry handle with wand storage.

  • With adjustable padded straps, waist belt and chest cinch strap, the backpack ensures comfort while you work
  • Multiple nozzles are included for ultimate versatility: poly adjustable nozzle (enables stream to cone patterns), wide flat fan nozzle (red, 0.25 GPM, angled at 70 degrees), narrow flat fan nozzle (yellow, 0.15 GPM, angled at 30 degrees), and foaming nozzle
  • Also accepts TeeJet nozzles

Rated 1 out of 5 by from Check the box. No WAND INSIDE!! Bought two. Went home (quite a drive)! And no wand in either box. Company must lack quality control. Unsure if sprayer works but pretty dissatisfied at this point.

I have used round up, in the proper ratio, can I rinse the tank out and spray fertilizer with it,, if so, how many times do I have to run water thru the tank...

Asked by: elmerT
Yes, you can rinse it out and use another chemical. To thoroughly rinse it, follow these steps: 1. Fill the tank with cool, clean tap water (never use hot water). Replace the cap and tighten securely. 2. Agitate the tank to rinse the chemical from the tank walls. 3. Empty the contents into gravel or bare soil. 4. Refill the tank with clean tap water. 5. Pressurize the tank and spray the water through the wand and nozzle for at least 30 seconds. 7. Empty the contents into gravel or bare soil. 8. We suggest repeating steps 4 - 7 at least 2-3 times (or until thoroughly cleaned. 9. Remove nozzle and rinse thoroughly.

How easy is it to pump up pressure while on your back. Or is it even possible or do you have to remove. Also how long does preassure last?

Asked by: Berry15
The backpack sprayer is designed to pump the handle while you are wearing it on your back. It is very easy to pump. It's hard to say how long the pressure lasts as it depends on how much solution you are applying. You will be pumping as you walk along your yard. We can answer all your questions and put your mind at ease if you would like to contact us at 1-800-311-9903. We look forward to your call Berry15.
