Lack of Pressure

• If, after pumping the sprayer, the spray has little or no pressure, first make sure all connections and gaskets are tight. If that does not help, the plunger cup (base of the pump cylinder) may need lubrication. Use petroleum jelly to lubricate the cup and the seal around it. Check for damage and replace if necessary. Check the information on the manufacturer's website for possible parts replacement. In cold climates, it is a good idea to lubricate rubber parts before winter to avoid drying and cracking.
