How much water do you carry?

[John_99_2007]

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.

what tip will you be using for 1000 SF?

How dirty is the surface?

Hey Mike, do your numbers change if your helper is wearing shoes when she is washing, LOL?

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.

[JCinNJ]

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.

Great video
met you in Tampa

Excellent video Mike. Back when I first started I used to just hook up to the customers house with no tank. I also quickly found out that older wells will dry up if you use a lot of water, so a water tank becomes an absolute necessity.

I use a 335 water tank and can have up to three machines running off it, for a total of 17gpm. 8gpm + 4gpm, and a 5gpm machine. Most houses have two water outlets and if I need to, I will hook up two sets of intake hoses to keep the tank from draining too fast.

I like the fact that you have 2 filters.
I run 2 pw off a 300gallon tank. And some times I link the 2 together when using my suface cleaner.

You are the man Scott. Not many guys join their machines together.
Saves you a ton of time, which of course you already know.
