Fix your battery powered backpack sprayer | Prime the pump

I got a new sprayer and could not figure out how to get it to spray. The battery was fully charged and when I turned the sprayer on I could hear it running but no water would come out. I tried what the manual said, I tried to prime the pump in a way another youtube video said to do. Nothing worked.
Finally, I decided to force water back into the pump through the hose and it worked. If you're having the same issues where your pump is running but no water is coming out, give this a shot.

Thank you!!! It worked!! My husband is so happy that he doesn’t have to purchase a third Kobalt sprayer! Thank you again.

[@johnallen-hu5lu]

Unbelievable. Imagine my disappointment when my brand new Stihl battery powered sprayer would not pump! After reading the instructions cover to cover, I went on my trusty KZbin and found your video. Though I didn’t quite backfeed the pump like you did, it was basically the same thing filling the sprayer tube and then putting my air nozzle on it and pressurizing it. Easy as pie and took right off. Thanks man!

[@shaze-10]

Thank you!!! Brand new out of the box Ryobi 4gal 18v backpack sprayer. I talked to two Ryobi customer service technical experts following their step by step troubleshooting instructions, but no luck. Taking something like this back simply isn't the easiest thing in the world due to where I live. This video was spot on!! Worked like it should after this!!

[@vincedude0458]

I have a different brand of battery-powered backpack sprayer and had the same problem. I followed your advice and now its working again. However, I went so far as to disassemble my sprayer to access the inlet and outlet ports of the actual pump. I then used a Waterpik to force water into the pump. After reconnecting everything, the sprayer was working again. Before I store the sprayer away for the winter, I will make sure to leave some water in the pump to keep it “lubricated”. THANK YOU

[@dFreemZ]

Wow! I had my backpack sprayer for over 3 years and just now experienced this issue. I followed your advice and in less than 5 minutes it's working again. Thanks! Saved me a couple hundred $$$.

[@randaldavis9332]

You are my hero!!! I was so frustrated with my brand new sprayer that would not work. Thank you for taking the time to create this video, as this method worked like a charm!

[@arrived001]

Thankyou so so much for posting this video! I brought this cheap Shogun 16V and couldn’t figure out how to get it going and it had ZERO instructions in the box or anywhere on line and your tip worked instantly! Thankyou so much!

[@rickpoquette533]

Thanks for the video! I did have to do one additional step to get mine to work out of the box, which was to actually turn the pump on while I was forcing water into the system as you describe. Was my last resort, but it worked!

[@cjcalhoon5799]

great video! I did this 2 years ago and it worked great. I put the sprayer away for 2 years then pulled it out to use it this year. Nothing. I tried the same method again. Nothing. So, I gave up and left it sit. I didn't drain the water out. The neighbor showed up today and I showed him the sprayer that was dead. I turned it on and pulled the trigger, and it WORKED!!! Leaving it sit for a few days must have primed the pump.

[@nodd85]

You’re a legend, thank you! I had no idea why my brand new battery powered backpack sprayer wasn’t spraying any water. This fixed it for me.

[@jeannepeterson2888]

Like all the others, I was ready to send it back - your video saved my weekend, Thank you very much for posting.

[@ZEYEOD]

Using Ryobi 4 gallon 4V chemical spray backpack, everything was put together properly, battery fully charged, etc. Tool wouldn't spray. I returned the tool and purchased a new one: same product. Of course, same issue; sprayer wouldn't spray!!! Called Ryobi tech support: 45 minute on hold wait. Used their chat, no tech help whatsoever. I saw your video. You said, "Prime the pump!" I used a hose as you demonstrated, and voila, the damn tool works fine now. THANK YOU VERY MUCH for helping me figure out the issue!

[@PushaDee]

Very simple fix for anyone interested. Turn the sprayer on and while holding the trigger down shake the hose back and forth quickly and it will prime in seconds.

[@TheLawnWhisperer]

@@PushaDee I love shaking my hose back and forth quickly… usually does the trick

[@richardhammond3655]

Was really happy when I ran across your video because I was having the same problem with a sprayer that I just brought home from Home Depot. Unfortunately you solution did not work for me - forced water back through the hose until the sprayer was full. Turned on the pump and no output from the sprayer hose. Will do a little more research and then back to Home Depot. Nice to see that your efforts helped so many.

[@Jeff-wi3cx]

Dude you are the KING of the Bosses. I got a different name brand and it worked I appreciate it.

Wow!! Worked excellent! I was just getting ready to take my sprayer back to Rural King when I found this video. Be careful when you unscrew the hose because there will be a lot of pressure there

I appreciate your help …have a new sprayer that’s been sitting for about a year …went to use it and, no water flow…followed your advice and had to suck some water through the tube and it works grear. Thanks !

[@hemdig]

Great video. I had to prime my brand new YT25E sprayer. I used your method by removing the spray trigger assembly and then pouring a small amount of water down the supply tube. Managed to do this indoors, without getting wet.

[@Armandot6]

I tried a few other methods they didn’t work. This is the only one that worked for me. Thank you. I was about to go get a new backpack😅. Also, I noticed if you do bursts of water it helps push the water in.

[@jjod4858]

I bought a 24 Volt backpack sprayer two years ago. I used it once, cleaned it out, and put it away. I did not use it for one season (completely dry in the tank). In April 2021 I tried using it again, and it did not pump the solution out. I called the company and I watched youtube videos. Nothing! I decided the unit was shot!!!!! I then saw a video on youtube. The guy said just bang the unit on the ground (Not hard, and I had about 1 gal. of water in it). I did and it started to work. Try that before you throw it out........ And also, keep about one qt. of clean water in the tank when you put it away. I don't know if this is recommended, but it will keep the pump ready to go. :)

[@johnthomas8845]

Bro, I had a Hart that was doing the same thing. I tried everything, and still no spray. I did what you suggested, and BAM... It did the trick.

[@brianthompson2045]

Took apart bottom carefully before doing anything with it. Gently tightened hose with regular screw driver. Gently checked all screws for tightness. They were fine. Lubed the o ring on bottom of tank inside or between tank and pump. Just enough. Then very carefully put all back together. Filled with 1 gallon water. Left water in over night to check for leaks while battery charged fully over night. Made sure in off position. Loaded battery on and turned to on position. Pointed hose end in tank and primed pump which worked perfectly out of box. Double checked for leaks and found none. Ready to go for spraying.

[@bobsimmoman]

Thanks man! - I was getting angry and about to send my new sprayer back. I watched your video and my new sprayer works now. Why don’t they put this in the handbooks? 😏

[@duanesapp4914]

I see you have a new handle on backpack sprayer in the newer videos. Do you have a video of what handle you replaced it with? I have a Chapin backpack sprayer and the hose in my opinion is too short. I would like to replace it and also replace the handle. Thanks

[@danielgomes4754]

I have the Walmart brand Chapin. You have to make sure to filter the fluid that you pour in especially if you are mixing powders. The filters get clogged easily. Also flush the fluids out and leave a little water inside the tank. Other than that I have not had any problems. The main issue I have with them is that the battery is exposed at the bottom. They should have done something to protect it.

brand new battery powered pump from cardinal... would not flow at all.. the hose was way too small to hook the hose up to it, but what ended up working was turning the pump on with water and sucking on the end of the hose.. broke the pump free and been working since. hopefully this is a one time thing though and i dont have to try and suck some herbicide through the pump

[@JbowlsGlassworx]

Very helpful. I feel stupid not thinking of it, but thanks ha..

My flo-master pump less can’t form a decent spray… might try this back flush to get any gunk out 👍

[@mymini911]

all you need is a Schrader valve, quarter inch fill it up with an air compressor and it will spray better than new and turbo charged

[@StreetKingz4Life]

I have the same sprayer with a fully charged battery but it won't start for nothing ,what u guys think?

[@brassfactor]

So what I did to prime it after trying their way for 30 minutes with no luck was to turn it on and stick the wand into the end of my shop vac and make it air tight and I let the shopvac suck the water into the pump and line. Worked really quickly. 😎🎼🎤🎺

[@bobdirienzo1292]

I have a Kobalt 4 gallon sprayer that has suddenly stopped priming. I tried to force water into the pump like you did. For some reason it doesn’t want to fill in this direction. I have a hose with a jet nozzle that fits right into the sprayer tube, but no water is appearing in the tank. I cannot see anywhere else where the water is going, so it’s as if the tube is preventing flow from the hose. Has anyone else had this issue with the Kobalt sprayer?

[@ranchmcgee4253]

Not sure if it helps but sometimes after I shake the sprayer the bottom draw inside the pump flips up.

[@Gitarzan66]

I couldn't do that, I already had my weed killer in there lol. Squeezing the trigger then flipping the power on worked for me! Greetings from Colorado.

[@michaelhlavaty7695]

I tried this, you're right you'll get wet. My sprayer still didn't work. As a last resort, I secured red cap and turned unit upside down and it primed immediately.

I have a Kobalt sprayer that suddenly will not prime. I tried forcing water through the tube and it does not seem to be filling the tank. I have a hose nozzle with a jet setting that fits almost perfectly into the backpack tube. But no water is coming out anywhere or into the tank. Has anyone else tried this method with a Kobalt backpack sprayer?

[@RobAnd110]

Another option is to unscrewed the wand, put the hose into the filled tank and turn it on It primed itself.
