Re: My \"new\" sprayer!
DMF sent me a PM with a list of questions. This is sort a pet peeve of mine, so the answers are going to be here in the thread where they belong. Most of the questions refer to the following photo:
The supply line from the pump is the one on the left of the regulator with the white plastic elbow coming up from below. The line from the bottom of the pressure regulator is the overpressure relief, which dumps back into the main tank. The yellow valve controls the boom and the red controls the the hand gun. The plumbing "cross" is welded to an upright that is threaded into a base welded to the machine frame.
As to which line does what on the regulator -- that took me some time to absorb as well. As I understand it, the pressure regulator works like this: The supply line (white elbow in the picture) is putting as much pressure as the pump supplies to both the gun and the boom. The pressure regulator works by bleeding off the pressure above what you set by venting some of the water out through the dump line (the one going out of the bottom of the regulator). So while the cross receives max pressure, the boom and gun actually have regulated pressure because the regulator is venting off the excess from the cross. Clear as mud, right?
My boom has 4 jets. No closer pics. I'll be happy to shoot some for you, but not right away. I am on a deadline to get some grass seed in, so if it is daylight, I am in my tractor seat trying to get the grading done.
The controls are very handy from the tractor seat of my 4410. I control the gun and boom from the valve and leave the pump running for the most part. This keeps my chemicals mixed, because everything is running through the regulator overpressure port and into the tank, keeping everything circulating. As was brought up in a thread several weeks ago, if your mix is foamy (glysophate is very foamy when mixed) a half capful of hot tub anti-foam conditioner will knock the foam right down.
