Build A Better Wand​

Spraying Concepts

Spraying costly and powerful herbicides like Celsius, Tenacity and Certainty require precision. You don't want to harm your turf by using a tip that produces drips or puts out too much product, even when spot spraying. You've invested in your turf, take care of it.

Important: Start by watching these excellent videos on the important principles of spraying. It's a fantastic series that explains the steps to getting this right. It talks about the different tips available that make the difference between spraying 4 gallons over 5k or 10k. Don't like to refill so often? Watch the videos. Droplet size directly affects coverage, and that comes from selecting the proper tip for the job.

Once you know the proper concepts of spraying, get setup on the business end of your sprayer. This setup, with the nozzle body, will allow you to swap tips and caps, depending on what rate you want to spray. Eventually, you'll have a whole set of tips and swapping them out to spray something different each day of the week will be easy.

Read the TeeJet nozzle thread to get a good idea of how the different spray tips work.

Parts

Pick a TeeJet spraying tip and place it into a TeeJet cap. The cap will hold the tip in place. It is important to pick a cap that fits the tip you are buying.

The tip and cap will fit onto a nozzle body. The nozzle body will stay on the end of the wand and the tip and cap can be quickly removed and changed for different spraying projects. Buy as many tips as you have spraying needs and then just connect them to the nozzle body as needed. A strainer can be placed inside the nozzle body to prevent clogs.

The nozzle body can then connect to either a CF valve or the wand itself. I like using a constant flow valve to prevent drips after releasing the trigger. With high powered herbicides, drips can be deadly.

The nozzle body or CF valve screw into a brass wand. The wand needs a trigger, handle, and swivel barb to connect to your existing sprayer hose. Use pinch or screw clamps to keep the hose connection tight.

Putting It Together

Drop the tip into the cap, and the strainer into the nozzle body. Screw the cap into the nozzle body and connect the body to the CF valve. Screw the CF valve onto the wand and screw the wand onto the trigger. With Teflon tape, connect the trigger to the handle, and with more tape, connect the handle to the swivel barb. Clamp the barb to your hose and you're off to the races.

Again: Hose and Clamp->Swivel Barb->Thread Tape->Handle->Thread Tape->Trigger->Wand->CF Valve->Nozzle Body->Filter->Cap->Tip

@WeedPatch your options are really limited with the ground drive pump on the Earthway. I would probably stick with the floodjet style nozzle on that sprayer.

Converting it to an electric pump would open up more options. Search franken-sprayer for ideas.

I just ordered the chapin 2 nozzle boom for the DFW, what are the parts required to make it compatible with the DFW?

You need a 3/8 BSP x 11/16 adapter. I got mine with my Chapin CF valves. They are handy to have around. I have not seen them sold separately, be it Chapin or some other brand. But look about the internet, you may find it somewhere. Maybe someone else will chime in.

I just built the wand and I'm having a pretty severe leak at the base of curved extension (not the threads). Anyone else run into this issue?

Do you have a gasket in that joint? It is a straight thread and really should have one in there. I put one in mine per TeeJet tech support's suggestion. You may be able to rob one from another sprayer. I know all my Chapin gaskets are close enough in size to work.

The wand to valve connection needs to be extremely tight unless you use an o ring. In absence of that, the connection is what I call wrench tight.

Anyone ever have any success with replacing the hose and wand on the new design of the 4 gallon Ryobi Backpack Sprayer? Everything was fine until I realized all the modifying that I had to do just to replace the hose. The stock hose on the ryobi appears to be 1/4" as opposed to the 3/8" hose that is used on the dfw wand. The main issue is once I took off the clamp that was crimped onto the stock hose, it then attaches to a barb which appears to be 1/4" so obviously the 3/8" hose that I purchased would not fit. I ended up buying a 1/4 swivel barb with 1/4 hose and currently waiting for those parts to arrive. My last question is say that I could find a flange barb piece that is 3/8" and fits into the stock pump, would that cause any issues with flow? (Example that pump is only able to output the flow for the 1/4" diameter hose as opposed to the 3/8 hose. This is probably really hard to picture so I'll attach some photos when I get home. I literally had to take the entire housing of the backpack sprayer apart to get access to the hose that attaches to the pump

Ok, so i bought the updated version 4 gal Ryobi one+ and all the goodies to make the DFW wand. The hose is so hard to change out i just wetted the 3/8 swivel hose Barb and pushed it as far i could onto the hose Barb. I'm inpatient and sending it back to Florida for exchange just wasn't going to cut it. I put the small hose clamp over the black hose where i was able to push it up about 3/4 the way up the barb and clamped it on. No issues so far and I'm loving it. I wish I had more things to spray down.lol. hope this helps. Can post pics tomorrow.

Thanks Grassobession! I reached out to Madao as he got it working without having to cut the hose. I ended up using a 3/4" mnpt x 1/4" fnpt adapter and it worked beautifully.

That looks great! The difference between stock wand and DFW wand is night and day! I'm glad you found a way to get that done! I was worried about it at first but then found the lawn forum and i no longer worry cause there are so many great people with great ideas here..

Yes sir, this forum has a wealth of knowledge. I've read though these already (DFW Sprayer Wand & TeeJet Nozzle Discussion). I'm hoping for a great looking lawn this year. Dude, we both have Troy-Built mowers, awesome!!!

I managed to pick up a Hart 4gal backpack sprayer on clearance at Walmart for $36 late last year. I can confirm, based on yush's picture that they are exactly the same as the new 4gal Ryobi backpack Sprayers.

Thank you for the adapter recommendation @Madao and @yush The 3/4" MNPT x 1/4" FNPT adapter was just what the doctor ordered! sprayerdepot link

I did a lot of reading in this thread, the Teejet thread and others to wrap my head around this and get it set up properly. I opted for a 30" wand as I'm 6'2" but otherwise stuck with the recommended parts list. It works really dang well compared to the stock Hart sprayer, and even more so compared to the 1gal hand-pumped Chapin I was using last year! BTW, sprayerdepot had every single one of the parts I needed for my modified setup and were cheaper than Spray Smarter. I'm actually looking forward to putting down some Prodiamine 65 WDG soon. I won't have to refill so many times and it will be a cakewalk!

Nice DFW setups…you found a much better adapter than I did at my local Ace.

The fewer the fittings the better....I suppose right ?

Just used my Milwaukee Backpack Sprayer - 1st time. Had a straight wand so I stole some parts off the handheld to fit onto the straight stick to get it to *curve down* for my Spring M app. Some of it was a bit leaky - even tho tight and gasket. I did not go full bore tight as I knew it was going to come up and I had to revisit this DFW thread for all the right parts...

I've watched The Lawn Forum's youtube video on this a few times and decided to put it all together. The bitly link for the quick cap, just redirects to the spraysmarter.com main page, and if I search for quick cap I get to pick from either black or white. I've tried looking this all up, and from my understanding and some charts I've seen online all of the various nozzles are color coded. I THINK I need a red quick cap to take the red nozzles (as is shown in the video). I can find the red cap on other retailers and Amazon, but unsure if that's the route I need to go, or if either of the 2 quick caps available at spray smarter would work.

Welcome to TLF!

You need a 25612-3-NYR cap and gasket for the more commonly used TeeJet nozzle series (XR, TT, AIXR). You can substitute the number between the dashes with the color code you prefer (3 = red).

I went to fix the link and something is a little screwy with their website. I can't get it to pull up when I search for that part number.

I received a DM from a fellow TLF user and thought I'd share our exchange in case it could benefit someone else:

This is a really nice set-up for the Hart 4-gallon sprayer you made. I myself am still trying to wrap my head around spray tips and parts and keep getting confused. Is there any chance you can go through the list of all the parts you needed for it? I bought two of the same sprayers and would like to use that same set-up. Looks like I need that 3/4" MNPT x 1/4" FNPT adapter to start. Thanks for any and all help!

Have you watched the YouTube video in the first post? Ware did a solid job laying out the components and putting them together - https://thelawnforum.com/viewtopic.php?f=4&t=12 It helped me visualize what was happening. Believe me, I had to watch the video a couple times, put together a shopping cart of all the parts a few times and confirm I was doing the right thing by reading through a lot of posts a few times before pulling the trigger on an order. It's pretty complicated!

The first thing to do with the Hart sprayer is unscrew the cheap plastic spray wand it came with - I used a couple sets of pliers to unscrew and separate it. That will leave you with a 3/4" female NPT end you can then screw the 3/4" MNPT x 1/4" FNPT adapter into. I'll lay out the differences between the DFW sprayer and my modified version:

DFW:
Hose and Clamp->Swivel Barb->Thread Tape->Handle->Thread Tape->Trigger->Wand->CF Valve->Nozzle Body->Filter->Cap->Tip

Mine:
Hart stock hose to 3/4" FNPT end->3/4" MNPT x 1/4" FNPT adapter->Handle->Trigger->Wand->Nozzle Body->Cap->Tip

I removed the references to thread tape in mine for simplicity. You should be putting a layer of thread tape between every single connection that's threaded and ware was smart to spell that out. Also, I removed the CF valve and filter because I kept reading that people were having issues with them getting clogged with battery powered sprayers. If you compare, mine is nearly the same set up starting at the handle.

Here's what I ordered from sprayerdepot.com, in order of assembly:
3/4" MNPT x 1/4" FNPT Brass Reducer Bushing
1/4" NPT (M) Handle
6466 Trigger Valve 1/4" FNPT Inlet
30" Curved Extension w/ Fixed Body
11/16"-16 Female TeeJet x Quick TeeJet Adapter
25612-2-NYR Cap & Gasket (White)
XR11006-VS XR TeeJet Extended Range
XR11004-VS XR TeeJet Extended Range
AIXR11004VP TeeJet Air Induction XR

I ordered a 30" wand because I'm tall. dfw recommended the 24" one. Your call there...

As for the tips and caps, that's it's own area of discussion - http://thelawnforum.com/viewtopic.php?f=4&t=33 There are a lot of choices for tips/caps and I think it might be more complicated than the sprayer assembly. As for the mechanics of it, tips mount inside the caps and can be swapped out. I've figured out that picking the right tip comes down to two things - what you are spraying and the volume at which you want it to spray. How to figure out the volume at which you want it to spray depends on how high you set your Hart sprayer and how fast you walk. And here's the thing - I haven't even sprayed my lawn with chemicals yet. I may discover I need a different tip because I'm not walking fast enough or too much/little is being sprayed... Wish me luck this weekend!
