Picked one of these up for Christmas- is there any reason to supplement with the TeeJet nozzles that have been outlined in this forum? I tested today with the fan nozzle that comes with the setup and it seemed fine. I know that the CF valve isn’t needed due to the battery pumping at a constant pressure, but wondering about the other pieces.

I have been on this form for quite some time and tiring to learn as much as I can. Bought this backpack sprayer and decided to spray down Prodiamine. My question is how to do you, or what is the proper way to clean it out? I tried to flush it out with regular water then added a little bit of soap flushed it out again and I still get the bright yellow residue at the bottom. Do you dump it back into the same place into the yard? Also is it okay to spray herbicides and pesticides (obviously not at the same time) any help would be appreciated.

^$150 with the battery + charger

It would be nice as a tool only, but they are not currently selling it.

Another option has hit the market.

Man, I wish I would have seen this before I bought the Chapin. I already have the Ryobi 18v platform across multiple tools, this would have been a nice addition.

I have the one gallon version and bought it as a tool only, I'm sure eventually it will come like that as well. I love the whole 18volt line from ryobi. I have their string trimmer and edger combo and it does the whole yard with plenty of charge.

I was having some trouble with my Stihl backpack sprayer this morning, so I went down to my local farm store and bought one of these. Wow! I'll fix my Stihl when it's a little cooler outside, but I may sell it after using this Chapin 20V today.

You know, as good and durable as the SG20 is, combined with Stihl's fairly extensive battery equipment line, and taking into account their customer base of professional lawn care companies, I'm very surprised we haven't seen a battery powerd sprayer offering from Stihl yet.

It looks like Chapin 63924 is a new 24V backpack. According to the specs it offers 2 hours of continuous runtime (15 more minutes than the Chapin 63985 20V backpack). It looks like they're using the same battery as they are use on the Chapin 97900 24V push sprayer.

@J_nick spotted one of these in a store.

LOL, man they are making it harder and harder for a guy with near 30k sf to stay “on the fence!” Neither my wife, my ortho specialist, physical therapist and I are ALL NOT impressed with the repetitive motion damage I am doing to my left elbow and arm with the pumper (arghhhh)!

Question: anyone know how accessible additional batteries are? Sources?

I ask as it takes me more than 2 hours to spray our entire property and at least one extra battery (probably 2 extra) are gonna be a must.

Hopes are high!

With 30k, would a push sprayer more better? I'm not sure about the 24v version, but my 20v version uses a Black and Decker cordless tool battery.

+1 A push/mounted/pull behind sprayer would be a good investment for 30K of lawn.

If I had a larger lawn than my 5K, I might think of DIY pull sprayer using one of the kids radio flyers.

To answer the question, the battery is the object at the bottom with the red CHAPIN 24V label on it. It's just like the drill batteries, there is a little button on the side you push it and it slides out.

Has anyone added a CFV to your Chapin 20V sprayer?

I need to do some spot spraying and due to the constant 35-40 psi it is on the aggressive side. Worried about spraying too much in one spot...

I think adding a CF valve could cause the pressure switch/pump to short cycle.

If you have calibrated your sprayer, it shouldn't matter - you would simply be adding the appropriate amount of product to the amount of water it takes you to cover say 1,000 square feet. As tempting as it is to lower the nozzle down onto the weed, your technique (ground speed, nozzle height, etc) shouldn't really change between spot spraying and doing blanket apps - only the amount of time you squeeze the trigger.

Amazon has this unit on sale right now for $139.99 with prime shipping. They are really tempting me to pull the trigger. :|

I use the 20v Chapin on an acre. It's doable but not optimal. I feel like I spend more time traveling to refill/refilling than i do spraying. It's also heavy on your back for that length of time. Don't get me wrong, it's the best i've used so far, but I'm still looking to upgrade. I'll either go with @Ware's Lesco setup or @Pete1313's Johne Deere setup.

You sure? The one I see for $140 is 20v version. The 24v version is $180.

Either way, quite tempted to pick one up myself. After 4 hours and 28 gallons (7 loads) yesterday my shoulders and arm is sure feeling it today.
