Bad spray pattern or low spray volume

A distorted pattern or low volume is almost always a clogged nozzle or dip-tube filter. Clean both, re-pressurize, and test.

Updated June 3, 2026

Applies to:

FGI manual and compression sprayers (HDX 190804/190805, and others).

What causes this:

The spray pattern is uneven or the volume is low. This is almost always a clogged nozzle or a clogged dip-tube filter inside the tank.

  • A clogged nozzle
  • A clogged dip-tube filter

How to fix it:

  1. Remove the nozzle from the wand.
  2. Inspect the nozzle for clogs or buildup and clean as needed.
  3. Remove and inspect the dip-tube filter inside the tank.
  4. Clean the dip-tube filter thoroughly.
  5. Re-pressurize the tank by pumping the handle.
  6. Reassemble and test the spray pattern.
