Hint for when using a lance style garden sprayer:

  • If spray still comes out of the nozzle when the trigger is closed, this is caused by compressed air bubbles in the lance tube. On first use for the day and between each charge always spray into the air or high up onto a wall or post to purge this air out of the lance tube through the nozzle. The spray will then shut-off instantly. This applies to all pressurised lance type sprayers, no matter what brand. If you extend a telescopic lance during use, air will be drawn in through the nozzle & so the same purging procedure will need to be repeated.
