TeeJet 23120 bypass regulator for your sprayer

[@Ransome2501]

I was looking for a way to add a bypass to my new Delavan 2GPM pump because it cycles like a machine gun. Man I got so excited watching your video that the second I saw you adding a bypass to your drain that I stopped watching and started piecing everything together. Running to the hardware store, back a forth to my shop. Then after a few hours and finally trying it out with great expectations what i got was my cycling problem solved but at the sacrifice of about 1GPM and a pump that doesn’t shut off while resting because it’s constantly feeding the tank with the bypass. I only used a two way hose Y not a regulator though. , Any thoughts. Thanks

I can't think of a solution for you. A bypass regulator is going to make your pump run continuously AND use some of the flow for it's operation. In a home you would have a volume tank to absorb some of the volume to give you steady pressure, but I can't think of an economical way for you to do this with a small sprayer. Sorry.

Thanks for sharing these details. I ordered the 60 psi pressure valve you have. The box identifies it as this correct model, however the valve knob says 150 psi on the top. Is this what your shows, or was my part possibly placed in an incorrect box?

I'm sorry, but I scrapped that sprayer a few years ago and can't find the regulator. I'd recommend that you reach back to where you bought it and ask them to check their inventory. Sorry.

I've just added this regulator to a 1 GPM @40 PSI pump discharge is fine and with shut off valve closed to nozzles I set and 40 PSI. Soon as I open valve it drops to 15 PSI. So question is do I need a shut off valve to the discharge side to close it off?

[@Neighbour_Al]

You set the regulator while the nozzles are running. The regulator diverts to the discharge side, so no real need for a valve. let me know.

[@BigKahuna_outdoors]

Ok tried it that way too but it would never get back to 40 PSI while running only while closed off hmmmm.

[@Neighbour_Al]

The spec os misleading. You get a maximum of one gpm OR 40 psi, but not both at the same time. Your pump is too small. You might change the nozzles to lesser volume versions.

[@BigKahuna_outdoors]

@@Neighbour_Al that's what I was thinking I could add the valve to close off the agitation side if I didn't want it to recycle may work. What you think?

[@Neighbour_Al]

@@BigKahuna_outdoors You can't break it by trying! I can't work without agitation, but go for it if you can!

why don't you guys show explain how to connect what hoses to what openings on the regulator...we know what it is to do but show what hose goes where and why coming out of the regulator!!!!!!!

[@Neighbour_Al]

This is a "bypass" style regulator. The fluid pushes against a spring loaded piston that lets fluid pass when the pressure reaches a set point. The inlet on this regulator is on the bottom with the bypass being on the side. The inlet is connected in parallel with your want/nozzles. When the pressure reaches the desired level, it shunts the surplus fluid aside. I use the surplus fluid to keep my spray tank stirred up. All of the fluid goes back to the tank when I'm not spraying, and the pressure at the nozzle stays constant while I'm spraying so that I put a predictable volume of spray on my trees. Looking at the video, you can see the outlet of the pump connecting to the bottom of the regulator with a pressure gauge to help me set the regulator. Does this help? I admit that no one documents it well in their catalog.

What disc are you using in your jet? I have a similar setup without the extra return and am getting fluctuation during agitation which i assume is back pressure from the small jet i used from Rittenhouse kit. I was wondering if i should put a bigger disc in or out an extra line in like you did. Does the return line affect your jet agitation?

[@Neighbour_Al]

Could you rephrase your questions? I regret that you have me a bit confused. I have a very high volume pump installed, so I give full volume to the eduction style agitator, limited volume to the extra bypass, and a steady 40 psi to the wand.
