Wanting to know if this unit would be over kill for an add on service for a lawn and landscape business. It is a Hydrotech brand rig. The whole rig was built by Hydrotech. It specs are 9 gpm and 3500 psi, belt driven pump,275 water tank, 30 gal chemical tank, diesel heater, hose, hose reels ect. He said he purchased it 6 months ago for $ 12,000. It is not cheap, wondering if I would be better off with a more entry level unit. Thanks for your help.
