10gpm or 8 gpm

To get the max pressure with 10 gpm you need 1/2 inch hose but for washing a house 3/8 hose does just fine. You don’t need 3000 psi on a house and if you keep the hose to about 100 ft you don’t lose to much psi and can use it for cleaning concrete. we run 10 gpm everyday with 3/8 hose and very rarely do we wish we had 1/2 hose.

Is your 10gpm being run from a 13hp engine? And have you ever tried a 1/2" hose?

You defiantly do not need 3000psi to clean a house or any type of siding material, not even 200psi.

No it is pushed by a big kohler and yes we have used 1/2 inch hose it is to fatiguing to be pulled around all day.

Thats why we use mostly 3/8" hose for residential work and bldg commercial work because it’s lighter and causes less fatigue on the operator.

What do you guys think about a 13hp running a 5.5gpm @2500psi? How would it work with a classic or gp hammerhead on concrete?

Great… I’ll run a 24in surface cleaner on that set up.

I was hoping that would be the case. Im used to running 8gpm@3000psi thru my surface cleaners, I was unsure if 5.5 @2500 psi would be too low to clean properly.

Thats what use and it works fine, not as good/fast as 8gpm/3k PSI w/28" SCer, but fine for me with the amount of concrete work I do.
