Nice job! That should get some work done. Is the bypass end of the regulator on top of the tank open or does it terminate with an agitation nozzle? With the exception of centrifugal or turbine pumps, the bypass side of the regulator should be kept open without restrictions.

The bypass regulator screws into a 3/4 bulkhead. On the bottom side of that bulkhead there is a piece of 3/4 pvc pipe that goes about 1/2 way down the depth of the tank. It has a 90 degree elbow at the end of it so that the bypass shoots out horizontally inside the tank. There is no jet nozzle or anything like that to answer your question. It's just an open flow piece of 3/4 pvc pipe.

The 90 degree pvc elbow at the bottom end of the bypass pipe is pointed diagonally so that the bypass fluid hits the sidewall of the tank. I thought this would create a whirlpool type current within the tank, helping the chemical stay agitated.

Ok. Then you will be fine. I would hate to see anyone blow a pump or cause hose to burst because the regulator outlet was restricted.

Thanks I thought about just screwing the regulator into the bulkhead and leaving it at that. The return chemical would just spray in from the top of the tank that way. Totally free flowing as you're saying. I went ahead and added the pvc pipe on the inside of the tank to give me somewhat of an agitation setup. Not sure if it will do much good, but I figured a pipe halfway down and 90ed out towards the sidewall would stir things up better than just spraying down from the top. We will see. I mainly spray Strike 3 and Resolute 65 WG.

What you did would be much better than just letting pour down from the top. If that was done, there would be too much foaming in the tank. If you do use WG chemicals, the normal set up of agitation nozzles fed by the high pressure side of the regulator is suggested. They settle easy and are a pain to re mix on standing.

Question.... What if I take the hose that runs from the pump to the hose reel, cut it, install a "T", run one hose on to the hose reel like it already is, but then run another hose from that "T" back to the tank and install a ball valve? Put another pvc pipe going down with an actual agitation nozzle on it. I could start the engine, open this ball valve and direct all flow to this agitation nozzle. Let it run for 5 or 10 minutes before I start spraying or while mixing, then close this ball valve prior to dragging my gun out and actually spraying?

That would work very well. Actually, by having the ball valve and using the right size orifice on the jet agitator, you can run the agitator constantly. Of course, running it at full open when you are trying to get that tank mixed. WG products need constant agitation while spraying. If I have a tank mix that was sitting, I also spray whatever was in the hose back into the tank for several minutes before putting it on the lawn.
