As you can see in this photo, the transfer hose used has already split on this sprayer, after only a few month's use. The plastic fittings are cheap and will not hold up in the AZ sun (notice the fitting holding the pressure gauge).
The company that built this weed control power sprayer rig skimped on hoses and fittings (among other things) to cut costs. Over time, the client did not save any money because these components had to be replaced.
It is important when buying spray equipment that you know what you are getting. Comments?
