Pump Pulsing Problem

[BrianD]

Anytime I use a tip other than my X-Jet, my pump pulsates - going form high presure to low pressure, back to high, back to low... Any ideas?

Brian,

I suspect what is happening is that your unloader is "cycling" due to either too small of a nozzle, or improper adjustment of your unloader.

Just a hunch! Are you postive you are running the proper sized nozzles?
