Compressed air sprayer

[JimDRIl]

I've got a small one gallon sprayer I use to spray Roundup and it just dribbles out when fully pumped. I unscrewed the wand thinking it had a clogged nozzle but was not the case, Anyone had this problem?

Take the hose off at the tank, pull dip tube and check for obstructions take every thing apart all the way to wand, also check hose for collapsing on the inside.

Sounds like there is an issue with the trigger valve. It may not be opening up enough. The chemicals used in those sprayers often damage the O-rings and valves. It would be a good idea to wash it out after each use.

My roundup can does the same thing. It's usually some white stringy stuff that must precipitate out of the roundup if it sits for a while. It plugs up the screen on the end of the pickup tube.

Roundup will do that. I've ruined a couple of barrel pumps with it.

ake valve apart, clean it, reverse rubber washer if you can, then ok until next time.
