2 wands good in theory!
I also got bitten with the one pump with two wands, even with a 13gpm unit.
With two wands and 4.5 tips still wasn't happy with the preformance of the washer.
Hey Eric,
When you used the pto on three pumps did you direct drive all three or belt drive with electric clutches.
Has anyone else tried silica sand water blasting hard to remove gum which hot h2o cant remove all the film. Seems to work good on heavy wear spots in front of main doors where the concrete has been worn. Also wooks good on rust on older concrete.
For us, we use a 6' lance on our wands, takes some time to get use to, but greatly increases productivity. Plus your feet will stay dry when detailing concrete.
