EDIT: 11/11/2022 There are two plugs for the pump housing. The red one is preinstalled for shipping the unit. The yellow/black one has a hole in it for ventilation, and should be used during operation. Thank you Spencer for pointing that out.

Setup and review of Simpson PS60843 pressure washer. This model has the CRX 420cc motor and AAA pump. Highly impressed with performance. Not recommended for washing cars at max pressure turn it down!!
