Great write-up! Thanks! :thumbup:

I understand and agree with your minimizing carrier logic. That's something stressed in the Rutgers Videos - with the right setup you can be very efficient with a backpack sprayer. Glad to hear it is working for you. I'm sure it really cuts down on the pumping too!

 

Where did you get the 2 nozzle wand or did you build it yourself?

 

Looks like he used this one.

 

No problem Ware! That Rutgers video is pretty awesome. I watched it several times a few years back when I was ready to get into broadcast spray applications.

Wardconnor, I bought mine from Amazon https://www.amazon.com/Chapin-6-7780-2-Nozzle-Backpack-Sprayers/dp/B006Y85G9M also available at domyownpestcontrol http://www.domyownpestcontrol.com/chapin-2nozzle-poly-boom-wand-67780-p-11499.html

Beat me too it lol

 

I was spraying just the other day and wished there was a multiple tipped wand to help speed the process.

Thanks!

 

Hey sorry to wake a few week old thread but has anyone bought the boom wand for a Greenworks (Harbor Freight) 4gal. backpack sprayer? I called Chapin today and they said that their thread pattern is patented and HF is no help either. I haven't seen a universal boom wand yet. I'm just trying to cut down my spraying time with a bigger swath and you would think all these things would just screw on easily to any sprayer.

No worries. That's why it's here!

I think they all use a proprietary thread pitch. Just a thought, you could buy a Chapin sprayer, swap the wands, put a Chapin multi-nozzle boom on the backpack, then use the 2gal tank w/HF wand for spot spraying. They also sell replacement wand parts, so you could build your own, but it looks like it may be just as cheap to buy a second sprayer.

I have a solo backpack sprayer hand pump.

I bought the Chapin cf valves red from Amazon. I bought the chapin 2 nozzle boom. The boom did not come with any adapters. The cf valves did however come with 2 adapters I threw the package away but on the back of the cf package it stated that it was compatible with all models with supplied adapters.

I didn't need the adapters for the cf valves because I bought the Chapin boom that went with the Chapin cf valves. Because I didn't need them for boom to valve I used the adapter to adapt from my crappy flimsy solo wand to the Chapin boom. It worked great.

I might work for you but its a gamble. The cf valve package said it was universally compatible.

I really need to get a dfw_pilot wand setup but am holding out because of funds. What I really need is a Mightyquinn Franken sprayer because of my large lawn setup. There is no shortage of ways to spend my money. In reality dfw_pilot would rather me save my cash for later years.

Oh wait.. There's more..... I also need another eley hose reel for this post and hose. Like I said... Everyone wants my money.

 

I agree. That post is begging for an Eley.

lol, I like the way you think! I'm always happy to see guys buy quality stuff - it will last a while and cost less in the long run. However, you are wise to remember that this hobby can quickly get you to buy a lot more equipment and toys than first imagined. And it quickly adds up.

I agree. That post is begging for an Eley.

+1

 

Thanks Ware and Wareconnor I appreciate the advice. :thumbup:

 

Long asleep thread......

Any reason you went with the 2 nozzle boom vs the 3 nozzle boom?

Thanks

 

Pump capacity. More nozzles running, the more GPM the pump needs to flow at a given pressure. My current set up involves a 3 GPM pump capable of maintaining 500 PSI. I can run a 4 nozzle boom on it and maintain 40 PSI at the nozzles.

 

So I have a Chapin 24 volt battery back pack sprayer and it claims to spray at 35-40 psi and the pump is rated at .4-.5 gpm

I ordered the 2 boom sprayer with teejet XR11002vs (yellow) nozzles so at .02gpm@40psi I would be right at 0.4gpm@40psi which is what I am getting now with my XR11004vs (red) nozzle.

I will just need to recalibrate my 1000sqft mix rate for carriers?

Thanks in advance for any advice.

 

Will the boom attach to a teejet wand? I builf a DFW wand....

 

Almost there!

Waiting on my teejet 3/8 to 11/16 adapter to attach this to my DFW wand!

 

Well done, a McGyver assembly !

 

Hey guys, I have a couple of questions on this. I have searched and know that the ideal spacing for tee jet 110 nozzles is 20". I actually have the Solo twin boom and it fits my Chapin sprayer and tee jets drop right in. I am in the process of add Chapin CF valves and tee jets along with a brass wand extension so its not so flimsy. My only issue is that the Solo is spaced at 24". Is this something that is going to cause issues or am I overthinking this?

 

@cutigers08 I think in theory you could raise your height off the ground to 24" to maintain the proper spray pattern....I may be wrong though.

It will be fine. Proper 20" spacing is only as good as someone's ability to consistently hold the boom 20" off the ground too. On that note, you could achieve the same 1:1 ratio by holding that boom 24" off the ground. But again, as long as you're close, you'll be fine. :thumbup:

 

That's what I was thinking but this year I am going to be spraying PGR and I want to get it as close to right as possible. I saw this thread and went and dug out the boom. Thanks for the input guys, because I already have two CF valves on the way lol.

 

So if anyone is interested in going this rout I would highly suggest the Solo boom. Its is 24" width but comes with filters and check valves. The Chapin CF valves are a direct fit and the Solo caps accept Tee Jets. You can build a pretty solid 2 boom sprayer without spending too much.

 

@985arrowhead what 3/8 to 11/16 adapter did you end up using...I am in need of the same thing!

 

I believe it was Tee Jet. I ordered after searching the web from a true farm parts supply shop.
