First Gas Station Help!

Hey guys! i got my first gas station job this weekend. I need a few tips i have a 5.5gpm 4000psi im thinking of mixing EBC 32oz per 2gallon SH?

Is this a good mix? or how would you tackle this job?

Do you have hot water

Yes it is hot water

Ebc is awesome.

Are you reclaiming the water? Or pushing into grass?
