What size buffer?

[ksroofs]

Hey guys,
I'm a bit new to the pressure washing scene, really have only been doing roof and exterior cleaning, no flatwork or anything of that nature.. I got a 8gpm cold water unit for rinsing on house washes, and hopefully some flat work ( for flat work I have a 250 gallon tank) But I want to add this unit to my roof cleaning trailer, and the biggest tank I can fit in there is 100 gallons.. I know with the float valve I will loose like 8-10 gallons off the top and another 10 off the bottom..

Will 100 gallons be enough for residential work with the 8gpm machine? Thanks!

Yes.....I have a 100 gallon for one of my 8GPM rigs and it rarely if ever runs dry. Only in the rare occasion that we run across low water pressure.

Thanks for the reply!

I have a 135 tank. No issues at all with the 8gpm. If we run the 8gpm and the 4gpm with surface cleaners it will dip down to approx 30 gallons. I just added a second supply reel for some larger flat work we have coming up so I can feel the tank with 2 supply hoses. I only added the second reel for when it's needed. So one reel has 200 feet of 3/4 supply abd the other has 100 feet of 3/4 supply. Or I can add the two together if I need 300 total feet. I will be plumbing the second Hudson valve this week.

I have a 50 gallon tank with an 8 gpm machine. We've had to learn to pay more attention to our water supply, but it has only ran out with really poor water flow.
