Great info here! I had the same problem and this helped.

Hello, I just found this site recently. I teach and coach for a living and I have been pressure washing on weekends and holidays for 15 years. I have two cold water 3500/3.5 gallon a minute pressure washers. I am looking at adding a hot water skid at 5.5 gallons to my 6x10 trailer. I do not currently have a supply tank, preferring to run off of the homeowners faucet. Most houses that I do have suffienct flow and pressure. My question is: Can you run a 5.5 or larger 8 gallon a minute pressure washer off of a normal house flow? Or do you have to have a large (350 gallon) supply tank to supply it? If you did run it off of a house flow would you have to have a large diameter hose? from 3/8 to say 1/2? Thanks in advance for the advice! Jake Collins

I have two soft wash chemical sprayers the use a hypro 4 roller pumps. They are connected to 35 gallon tanks and outflow through normal household 3/8 inch hoses. No bleach goes through my PW and I can stand on the ground and SOAK 3 stories high with a normal 5 position sprayer. Downside is that I have another engine to maintain and a tank to clean out. Also have to be careful not to run tank dry as that will ruin a pump in a hurry.
