Thank you all for this thread with the material list and pictures.

I completed my assembly for the modified Chapin 97902 24v this afternoon. Very happy with it, can't wait to use it.

My sprayer is no longer working. 😡
Very disappointed. I could turn it off and on and hear the pump running, but it doesn't seem to be pumping any liquid through. I tried messing around with the boom and spray switch with no luck.

Any one else ever had this issue?

You probably lost prime. I don't think the pump is a self priming unit, not strong enough to keep sucking air until liquid is pulled through. Hopefully somebody else can explain how to get it working again.

Take the hose off where it goes into the boom/wand selector and pour water down the hose into the pump with the pump on until it starts pumping again. Then reattach to the selector quickly without losing much water if possible. It happens to me almost Everytime and I'm too dumb to figure out a way to make it not happen. I'm thinking it loses prime when you take off the bottom drain

it's working again!! That really helped!

So what exactly is causing this issue? It's a bad idea to remove the bottom drain? I done it many times to clean the tank I guess I'll need a separate drain for that?

I think a separate drain hole would keep the line into the bottom of the tank full and the pump primed but I'm no engineer. Terrible design

well, I used my sprayer for the first time today to spray some iron and zinc. One good bounce and the sprayer bar snapped off. Here's to figuring out how to fix it.

This ⬆

I had this same problem. Take the hose off at the bottom and connect it to a water hose and turn the water on. I use this same method to clean out both the boom and spray wand hoses as well.

Does anyone have a suggestion for an equivalent or replacement part for this 3-way valve?



It is just not the lever, the valve itself is broken and leaks. Have already requested a replacement from Chapin but that will take weeks.

FML 🤦🏻‍♂️
The same thing just happened to me today. I just ordered this 3 way valve from Amazon:
Beduan 3 Way Shut Off Ball Valve, 3/8" Hose Barb 2 Switch Brass Y Shaped Valve https://www.amazon.com/dp/B07N5ZWLHJ/ref=cm_sw_r_cp_api_glt_fabc_MNZFWJMJWV08QZDA2SZA?_encoding=UTF8&psc=1

I hope this works.

This chapin sprayer has too many cheap parts

Thanks @somathnao. This is helpful.
Do you plan to mount or attach it to the sprayer?

I didn't do anything fancy, just reattached the hoses into the 3 way valve. It's just hanging to the side, doesn't look like it will fall off or anything =)

You could easily put one of those pipe straps around a hose and use a self tapping screw into the plastic housing of the old valve body. Or just let it hang.

Back in March of 2018 @TulsaFan posted his parts list that many people have used to modify their 97900 (His parts list was based on the many posts of anybody on TLF Chapin thread back then); however, the mounting has changed SOME for the 97902 that is currently being sold.

I am in no way trying to take credit for this, just want to help other newbs like myself make a tricked out Chapin 97902 with the help of @TulsaFan's parts list.

I tweaked things to only get parts from 3 places:Amazon, Sprayerdepot and Menards. You can substitute Lowes/Home Depot/Ace, ect for Menards parts.

This is the parts list I used today to modify mine. Cost: $113.88 as of 6.27.21

Sprayer Depot Parts:
(2) Diaphragm Check Valve Nozzle Bodies:Teejet 22251-311-375-NYB(They have a single 3/8" hose shank)
(2) Nozzles for contact products:TeeJet XRC11004VS (You can get poly to save money if you want.)
(2) Nozzles for systemic products:TeeJet AIC11004VS (You can get poly to save money if you want.)
(2) 50 Micron Strainers:Teejet 8079PP50
(2) Teejet Clamps QJ111HP34 (This clamp does have the 90deg bend, though Sprayerdepot's photo shows it's straight)
24" 3/8" ID Clear hose(Original list had 2 different hose types, but I had no issue just using the clear.

Amazon Parts:
(1) Barb Ball Valves (3 pack)(only need 2, but the 3 pack was cheaper than other 2 packs)
(1) Clamp Mounting Kit (mini pair) (Very cool item that allows your to use 3/4", 1", or 1.25" tubing.)
(1) Box of (10) Stainless steel clamps (You need 9, but I used 10, i'll show below )
(1) 3/8" Brass barbed tee

Menards Parts:
(1) 3/4" EMT conduit need to cut down to 22" (Others have used PVC, dowel, pipe.)
(2) 6mm x 35mm Hex Cap Coarse Bolt (Has to be 35mm or more, factory bolt was 6mm, so this fits the hole well.)
(1) 2-pack 6mm-1.00 Flange Lock Nut (Don't need flange, but its better in my opinion. Could use normal lock nut)
(1) 2-pack 6mm x 18mm Fender Washers (Need fender as hole in mount is bigger than bolt.)

For the stainless steel clamps are they 9 of the 5/16" ones? Looks like it's going to be a while if ordered from amazon so I may just go to the store but just wanted to make sure that was the right size.

This is what Amazon said I ordered, recision Brand - 33040 M6S Micro Seal, Miniature All Stainless Worm Gear Hose Clamp, 5/16" - 7/8" (Pack of 10)

Just picked up a gently used unit for $250. Came with a three nozzle boom which didn't perform well (left stripes), so I ordered a 2 nozzle boom. What nozzles is everyone running?

I had a similar issue I recommend a psi regulator either 29 or 21 psi. That along with t jet nozzles made the difference for me

They have the 21 psi as well

My pump is toast. I've tried every trick under the sun to revive it and it's still not working properly. I it barely has enough power to spit out of 1 nozzle.

Should I bother to call Chapin for a replacement or just replace on my own?

You can get a replacement for$20. I went looking for more power and ran into issues, so stick with the Delavan Powerflo 2200-201-SB 1.2GPM for best results.

Good stuff @Spammage thank you. Is that replacement for $20 directly through Chapin? Everywhere else i'm seeing it for ~$35
