    I have an older Lesco 300 gallon sprayer with a hypro d50 pump.
    I was spraying a yard and lost pressure I checked the tank I still had
    around fifty gallons of product that was building alot of foam.
    I added de foamer and continued to use with no success. My bypass line
    was discharging a frothy liquid at this time I have checked my fittings
    and all do not seem to be leaking. :confused:

    Let me ask you does the unit build pressure with the gun or wand released but when you go to spray and depress the trigger it then losses pressure?
