Why is the orifice size of pressure wash nozzle important?
A common misconception in the industry is one nozzle fits all pressure washers. Wash nozzles come in different orifice sizes which are determined by water volume (gallons per minute) and pressure of the washer. To obtain the rated output pressure and volume of your pressure washer it is essential that you use the proper nozzle size. Refer to nozzle selection chart or call our service department @ 1-800-535-9919. 7. How do I contact Chaffee-Ward? Chaffee-Ward can be contacted toll-free at (800) 535-9919.

Water in the fuel is one of the leading causes of fuel pump failure especially with a pressure washers proximity to water during normal operation. You can help prevent this by installing a fuel filter/water seperator, part # 2-9905. See the filter section on the parts inventory page for more info. 9.
