  1. How much hose can be used, and what size?

    1. we have used 300' of 3/8" high pressure hose and it still had a kick to it, use at least 150' most days.

    2. You can double the hose length to make it 50 feet long on this Powerhorse pressure washer and it will not effect your pressure.

      For every foot you add after the 50 feet you will decrease your pressure by 7 PSI, the hose is 5/16 inch with 3/8 inch quick couplers.
