Groundwater In Pressure Washer?
Hello Everyone:
I have a Generac 2700 psi pw. I live in N.E. florida and city water is very expensive here. I was considering using my ground water to power wash my roof. Would I be harming the pw in any way if I did use the ground water. I assume it would not harm it if after I flushed the pw out with city water? Any opinions? Many thanks: Don

The 2 main things to consider are is the water clean [no trash, heavy sediment, etc] and is the supply [gallons per minute] sufficient.
Just read your other thread,
When I lived in fla I had well water and the well pump did fine PWing my mobile home. I don't remember the size of the pump but it was a jet pump with a 105' deep 2" well. I have no idea how the cost of city water compares to the electricity used and wear and tear on the pump.

What I mean by ground water is, when we had the house built, we had a sprinkler system installed and it runs off of a pipe in ground(65ft) to supply our sprinklers.

If your sprinkler emitters are handling the water without problem, the it should be fine with the pressure washer. THe only problem I see is a high unregulated pressure from the well pump. Is there a way to buffer it, like a pressure tank? How much pressure is being placed at the emitter heads? Where is your pressure switch and what is its cut in and cut out pressure? I can only envision the pump going through a cycle every few seconds with either the sprinkler system or the pressure washer.
