    How many gallons of water would you estimate it takes to clean 1000 square feet of concrete?

    I can do it with 220-250 with a 8 gpm machine.

    Mike,
    Do you carry all the water you need or refill on site?
    Thanks,
    John

    Thanks Mike for the info here and all your other threads.
    Do you think a very small tank (around 65 gal.) would be enough for residential services.
    I'm considering 4-8 gpm washers but trying to build a lightweight rig. I know I would need to be careful if I was on the trigger for an extended time but thought this small setup might work 99% of the time.

    Just to be clear, I would be using onsite water source.
    Asking about a 65 gal "buffer" as described in the video.

    you can get by with a 35 gal tank if you are running a 4gpm rig, I did that for a couple of years. This year I have a 8gpm and a 4 running at the same time and I have run dry a 290gal tank. You should be fine with a 65gal tank.

    65 should be fine. Just make sure it is full all the time. Household sources range from 5-10 gpm.
