Ok, so got my Chapin backpack sprayer....go to test it out today so I can spray Prodiamine....battery is charged.

Battery in, water in tank (for my practice run). I push the switch to on...I think...the switch has a rubber gasket around it (for lack of a better word). There isn't a satisfying "click" or anything when I turn the power to on. Anyway, push the switch to on, nothing happens. Should the pump come on? When the instruction manual says "spray back into the tank" to prime the pump, does it mean spray w/the wand? Or from an external source? What should I do if the pump doesn't turn on when I turn the switch to on?

Not an auspicious start to my backpack spraying career:-/

The pump should come on when you hit the trigger on the wand. Mine sometimes sputters a bit when the switch is turned on if there's no liquid left in the pump, but otherwise it doesn't do anything until you hit the trigger. I think spraying back I to the tank is about filling the hose/wand with product. Any chance you have a multimeter to check the battery?

I know this is going to sound super obvious, but make sure the battery is pushed in all the way. Mine was a little difficult to get it to click in all the way.

I'll check on the battery again... Did check it but never hurts to really push it in there

So pump comes on when want trigger is pulled. interesting. Am I doing something won't with the wand? How does the pump know when your squeezing the wand (maybe a stupid question, but doesn't seem to be a mechanical or electrical link between the two?)?

If the pump comes on when trigger pulled and turns off when trigger released it is working as intended

@gatormac my pump never comes on (at this point). I'll message with it more today when I get home from work. Will also check the battery with a multimeter to rule that out.

So I'm going to bump this and ask one more time before I go return my pump...in theory, after charging the battery on a new Chapin, I should be able to out the battery in, turn the power switch to on, pull the trigger on the wand, and have it spray. Correct?I'm not missing something am I?

If it's not working like it should, give Chapin a call. I had to send in my 24V push sprayer for repairs(they paid for the return shipping) and they sent me a new one. The pressure switch failed, and I got a call that they were sending me a new unit. It arrived today.

 

[gatormac2112]

I had to send my unit in as well, they have it right now. My pump wasn't shutting off when the wand wasn't depressed, it was on the whole time. The OCD in me made me send it in even though it was spraying.

Give customer service a call and they will take care of you.

Did you make sure the top is screwed on to create a tight seal?

The top doesn't actually need to be on for it to spray

 

[Killbuzz]

To have spray correctly it does. After messing with mine it would actually be best for him to leave it off. If the pump is actually working it will kick on and continuously try to pump. So if it doesn't it's either the pump, the battery or the switch.

 

[mrigney]

Right now I'm guessing the power switch is screwed up. Having no reference, I can't be sure...but it feels...not like I would expect. It's as if you can't really turn it from off to on (and vice versa). I'll give Chapin a call tomorrow.

Yeah, it should have a click.

Did you check the battery with a multimeter? If you've got voltage, with the battery in-place, try jumping the connectors. That should isolate the switch from the circuit. If it runs, you know it's the switch, the connection itself, or the wiring to/from the switch.

I just started to test mine. Not happy.

I charged battery. Put it in all the way. Flip switch and a motor sounds like it is running. I squeeze the handle and absolutely nothing happens. I look in the manual. I see "Unit runs but does not spray". Possible reason: Pump not primed. Correction: Activate shut off handle until liquid sprays out. Release handle and pump will shut off.

So. After sitting for five minutes waiting for liquid to come out.... Ready to return it and try something else.

So you have it turned on and it's making a sound the entire time but nothing sprays out?

Try tilting the unit about 30 degrees and spray for
10 seconds.

Well, I have egg on my face. So, the story above is true. But went inside and started the return process through Amazon. Meanwhile, the unit is on my workbench full of about a gallon of water the whole time. After lunch, I figured I better dump the water and start drying it to send back. But first, I decide to plug the battery in again and try just one more time just in case, thinking I will just get the same result.

Well, now it sprays water and shuts off when the trigger isn't pulled and starts again when it is. I don't know much about how long it takes to priming the pump and I couldn't find any literature in the manual about it. But sitting with a gallon on my bench did something.
Now. About to go kill some weeds!

Just so long as it's working! :thumbup:

If the pump ever doesn't stop when letting go of the trigger just tilt it while spraying and it will fix it. That rarely happens and only does right after filling it.

Happy spraying!

@gatormac2112 Thanks for the tip. It's been a long week for me with almost nothing working right. Basement flood from cheap water connections, Echo trimmer strung backwards, then this. How happy I was that it worked and sprayed like a champ!
