Bought a stanley back pack sprayer and chemical wont come out the wand when you press the handle. the nozzles are clear and the pressure is build up. i don't know what to do

Question edited for clarity, ' won't ' is a contraction of 'will not', 'the word 'want' is a request for something, they aren't interchangeable. ;>)

You sprayed has two handles, one on the wand and one on the pump.

Replacement wands are readily available. The pump is very simple in the way it works, there is a sealing gasket on the piston in the tube to create pressure and a non-return valve at the bottom of the tube to stop water flowing back. Check that they are clean and not obstructed.

It looks like the sprayer is made by Chapin and badged to Stanley.

It is probably plugged up with dirt or dried chemical. Release pressure with safety pull -out valve. Unscrew nozzle &unplug it.

Make sure the injector is turned on. Clean the nozzle or the strainer if either are clogged or blocked. There may also be dried chemicals in the injector; dissolve them by running warm water through the injection tube.
Check to see that the faucet is open if the engine is running but the pump is not building maximum pressure. If the unit has been stored in freezing temperatures, you'll need to thaw it out completely, including the gun, wand and hose. There may also be air in the pump. Allow the engine to run with the gun open and the wand removed until a steady stream of water is released. In addition, make sure the adjustable pressure knob is set to the maximum position,
Clean the nozzle if the engine is overloaded, as the nozzle may be partially blocked. Reduce excessive pressure by using the pressure adjustment knob.

When you pump the handle is there resistance? If there is, pressure is building up in the sprayer.
If there is no resistance, the sprayer pump is probably deteriorated and should be replaced.
If there is pressure and when you squeeze the trigger nothing comes out, remove the nozzle and make sure there is nothing plugging it.
Good Luck,

Hi,
The handle that you use to pump that sprayer will twist and come out... then you pour the water and chemical through that larger hole...replace the pump...twist it tight and then pump the pressure...

You can download the manual here: http://www.farmprotractors.com/hdcmanuals/PW2200-03435.pdf

It is probably the same manual that came with the unit.

As far as pressure... hook up the water supply hose and turn on the water supply. Let the supply hose purge all of the air out. Then turn off the water and connect the high pressure hose. After that turn the water supply on again with the engine off and squeeze the wand trigger. Make sure all of the air is out of the high pressure hose. Then start the unit...
Once the engine has stabilized rapidly squeeze and let go of the wand trigger several times. Your exersizing the bypass / unloader valve spring. By this time you should have good pressure. If you have owned the unit less than 90 days and your sure you have a warranty issue use this link to contact the company:

Some of these units have a sliding assy on the wand that slides toward the ouput nozzle for adding soap / chemicals. If the slide is not pulled back toward trhe wand and locked into place you will not have any pressure either.

It appears from reading the manual that this particular unhit had 2 different nozzles. One for chemicals and one for high pressure. Plese make sure you have the high pressure nozzle installed. The BLACK nozzle is for chemical use. (page 5 of manual link above)

The red, yellow or white nozzles are all for high pressure with different spray patterns.

This is about the best I can do for you Ron. Hope it was helpful.
