leaf F.A.Q & Troubleshooting Guide leaf

Below is a list of Frequently Asked Questions and their answers (the questions most asked of our Consumer Service Hotline staff), which you may find useful, followed by a detailed Troubleshooting Guide.


Q. I am getting air out of the nozzle, but not fluid/spray solution.




The siphon tube might be clogged, missing or loose. First, make sure to remove all pressure from the tank. Then, disconnect the hose from the tanks by unscrewing the compression nut (poly tanks only) and removing the hose from the tank nipple with a simultaneous twisting/pulling motion. Check to see if the siphon tube(supply tube) is firmly attached to the hose insert. If not, reinsert. If the tube is clogged, try to unclog. If the tube is missing or you cannot unclog the siphon tube, contact our Consumer Service Hotline at 1-800-253-4642 for a replacement.
Q. I pump the sprayer, but it will not pressurize/hold pressure.




Follow the instructions in your Owner’s Manual to disassemble the pump assembly. Check the plunger cup or plunger cup o-ring for cracks or splits. If it is not damaged, lubricate it with mineral oil, olive oil or petroleum jelly (petroleum jelly is best) and reassemble the pump assembly. For replacement items, purchase the 1916H kit. To purchase the kit, check with our Consumer Service Hotline to (1) verify the 1916H kit is indeed the kit you need and (2) determine which retailer’s carry the kit. Please call 1-800-253-4642.

Q. How do I dissassemble my flow control (shut off) assembly if it is plugged?




NEVER attempt to repair your sprayer while it is under pressure. To release pressure, follow the steps in the below question "How do I release pressure from my sprayer?" Once you have safely released all pressure, follow below instructions.




Remove hose assembly from tank



Remove wand from flow control



Remove hose from flow control

Remove any dirt or foreign substances and flush with water.



Remove cap from bottom of flow control



Be careful not to lose the spring

Remove any dirt or foreign substances and flush with water; screw cap back on.



Unscrew trigger mechanism from flow control grip



Be careful not to lose red washer

Remove any dirt or foreign substances and flush with water; reattach trigger mechanism to flow control grip


Reassemble the hose assembly -- attach wand to flow control, flow control to hose and hose to tank.



Be sure siphon tube is firmly seated into the hose insert prior to reattaching the hose assembly to the tank.


If you are still experiencing difficulties, call our Consumer Hotline at 1-800-253-4642


Q. Where is the o-ring that the “Owner’s Manual” says must be lubricated?
A. The o-ring is on the white or pink insert that is on the end of the hose which you inserted into the tank nipple.
Q. Can I use diesel fuel or gasoline in my sprayer?



Q. Can I spray paint or solid stains with my sprayer?



NO!! To spray such thick, viscous fluids, you need an airless sprayer. Be sure to read the instructions provided by the paint, solid stain, etc. manufacturer for the best means to apply their products.
Q. How much chemical should I put in my sprayer?



That question can be answered ONLY by you and the chemical manufacturer. Please read their label instructions or check their websites. NEVER FILL ABOVE “MAX” FILL LINE ON TANK11
Q. How much pressure will my sprayer hold?



The pressure you achieve by pumping varies depending upon (1) the model of the sprayer, (2) how much liquid is in the sprayer and (3) how strong you are. As a rule of thumb, pump the sprayer only until you feel a strong resistance.
Q. How do I release pressure from my sprayer?




If your sprayer is equipped with a pressure relief valve, you have two options, depending on the sprayer model you own. (1) point the pressure relief valve away from you and pull up on the red or yellow nipple and hold open until you can no longer hear the air escape or (2) point the pressure relief valve away from you and turn the yellow knob clockwise until you can no longer hear the air escape. If your sprayer is not equipped with a pressure relief valve, tip the sprayer upside down and depress the flow control (shut-off) until no more liquid or air escapes from the nozzle.
Q. What is your warranty?



You will find the length of your limited warranty on the original carton or in the “Owner’s Manual” that was included with your sprayer.  The specifics of the warranty are detailed in the “Owner’s Manual.”  The warranty statement itself is on the Warranty page of this website.
Q. How do I clean my deck/wood/masonry sprayer?




Each chemical manufacturer has specific recommended guidelines for cleaning up after using their product. Please follow their procedures. If the manufacturer recommends cleaning with Mineral Spirits, then you must remove the Mineral spirit residue from the sprayer/hose/flow control/wand/nozzle by thoroughly rinsing with warm dish soap water, followed by a thorough clear water rinse. In any case, be sure to dispose of any chemical and/or chemical residue safely and responsibly.
