Just remember, your water supply has to be higher than the GPM of the washer..... if the garden hose only supplys 2 GPM, your washer can't supply 3GPM and will run dry.
(My water pressure and flow is terrible- even my old electric Karcher will run dry if I have the lawn sprinkler running at the same time)
