How do you refill?


Remove all pressure by keeping the hose open until no pressure is left. place pump handle down toward tank. Turn count counter clock wise to unscrew. Take assembly out of tank then fill tank. Reinstall in reverse order.

Graco x9 won't hold pressure


If it comes up to pressure but won't hold it when the motor stops, you have either damaged packings or a bad check ball-to-seat seal. If it's the check ball(s) not seating properly a real good cleaning should take care of it. If it's the packings the only remedy is to replace them.

No pressur in my home and garden sprayer


You have a leak. First ensure the pressure relief valve is closed. You can try spraying soapy water on the outside while pumping it up, and look for bubbles. The one way valve might be leaking, too. Good luck.

Lid does not seal---very loose


If sprayer doesnt seal against pressure, I suggest check cover gasket A (image 1). Check pump cylinder gasket B (image 2) and additionally, check the procedure if pump dont build pressure. on how to remoce pump cylinder on follow lines.

If pump doesnt build pressure... in most instances, failure of the pumo to build air pressure in the sprayer is due to dry or worm plunger cul leather. To work on cup leather, always remove plunger from pumo cylinder. Do not attempt to oil cup leather through breather hole in **** cap.

First, unthread pumo cap A (image 1). If cap is too tight, and if pumo will build even slight temporary pressure, pressurizing the tnak will make it easier to loosen cap. Once cap is lossened, release tank pressure. Hold pump cylinder by inserting hand through tank filler openning (image 2), and unscrew cap all the way. Pull plunger from cylinder, and remove cylinder from inside the tank.

Place a few drops of clea oil (not heavier than SAE 30) on leather, and massage into leather until it is soft. Replace plunger cup leather if damaged (image 3). to remove plunger leather assembly, use coin rather than screw driver in the slot of the plunger cup retainer. To reassemble, hold pump cylinder in tank openning, with squared edge of flange, at top of cylinder, toward tank wall.

Hope this helps to solve it.

Then rotate clamp counterclockwise to stop and lift out.

My ChapinSpray N Go sprayer won't build air pressure in the tank when I pump the sprayer


Sounds like a faulty seal to me. Submerge the container in water and pump, bubbles will rise from the seal. Easy to fix, I had a look and you can pick up a seal replacement kit for this model at Amazon.com for under $12.00. You should also find them at any reperitable hardware store. Hope this helps :)

I need the manual for model # 1125D 2.5 gallon sprayer. I can not find it anywhere in the house or garage and I need to use it in the morning


Howdy. I was at the Chapin sprayer website and they don't list a model #1125d or similar. If you have any additional information, I'm sure we can get you a manual tonight.

I have a chapin 21210. i pump and pump and the only result i get is air. why isnt the spray coming out?


there should be a thin tubeinside the lid that extends to the bottom of the canister that picks up the fluid. Sounds like it might be missing or not connected
