I inherited an old Solo 457 pump that has not been used in years. I can't get it to pressurize despite pumping the handle for several minutes. I did see a place on the tank where you can put in a bike pump (schrader valve??). Can this be used to pressurize? I already have 2 gallons of liquid ready to spray in the tank.
