I need to move some water from a river 300 feet to my cabin to do some pressure washing …. I have a 4200 psi Simpson pressure washer ….. I have 300 foot of garden hose. What size water pump/or semi trash pump do I need to make this happen so that pressure washer get enough water…. Is a 1 inch sufficient or a 2 inch …. I’m unsure if there is enough pressure from the output side of the pump when spanning 300 feet …. There is no incline …. Pretty much level all the way …. If I used a 2 inch semi trash pump then reducer coupling down to a 5/8 inch to attach the garden hose seems it would create more pressure and increase gPM to the pressure washer? Or would a simple 1 inch water pump be all I need… I would use an inline screen in the line for any debris if I use just a 1 inch water pump … but pretty much the river water is clean with exception of grasses… any ideas on the project or am I over thinking this
