FlowZone Tips: Cleaning Your Sprayer

Battery powered backpack sprayers are typically an investment for your home or business. Whether you're using it as a garden sprayer or a pest sprayer, it's important to clean your FlowZone after each use so it lasts for many jobs to come. Not to mention, storing a dirty sprayer could damage it and void the product warranty.

Luckily, FlowZone makes it easy to flush out residual mixtures.

To clean your sprayer tank and inlet filter automatically, first dispose of any product from the tank safely based on the manufacturer's instructions.

Next, fill the tank with fresh water and spray into a suitable location for 3-5 minutes. This should successfully clear up the filter and pump.

If you're still experiencing restricted flow after following those steps, it may be necessary to clean the inlet filter manually. Note: It is generally not necessary to manually clean the inlet filter. Please be gentle when removing, disassembling, cleaning, reassembling, and reconnecting the filter to prevent accidental damage.

Here are some steps to ensure your sprayer is prepped for the next time you spray:

  1. Safely dispose of all contents in the tank per the label of the product being used.

  2. Thoroughly clean the tank with fresh water by spraying for 3-5 minutes to remove excess residue.

  3. Remove the tank lid and the tank strainer.

  4. Reach into the tank and remove the inlet filter by pulling it directly backwards from its point of connection.

  5. Remove the rubber tube from the pump inlet filter.

  6. Flush both the rubber tube and the pump inlet filter with clean water.

  7. Reconnect the rubber tube to the pump inlet filter.

  8. Reconnect the tank filter to the connection point.

  9. Fill tank with fresh water and spray the water into a suitable location to check if the flow restriction issue has been resolved.

Following these steps should resolve issues caused by a clogged filter. If the complication persists, please reach out to our techs at 1-803-339-2500 or email
