Pressure and pumping
Why your sprayer loses pressure quickly, and how to fix it
Rapid pressure loss is almost always a worn pump piston seal. Grease the piston O-ring first; if it persists, install a pump repair kit.
Read the guideSprayer will not build pressure or pump at all
If the pump will not build pressure, the piston is usually dry, cracked, or seized. Lubricate and reseat it; replace the piston cup if needed.
Read the guideSprayer only sprays at low pressure
Weak spray is usually a partially clogged shut-off or nozzle, or a pump that has not fully primed. Depressurize, clean the shut-off and nozzle, and let it prime.
Read the guideMaterial overflows through the pump barrel or the handle rises
This is a check-valve problem: debris under the valve, or a chipped, torn, or swollen valve. Clean the check valve and its sealing surface, and replace the valve if damaged.
Read the guideLeaks, drips and spraying
Liquid drips from the wand when you are not spraying
A wand that drips after you release the trigger usually has a worn shut-off valve or valve seat. Clean the seat and replace the rubber disc.
Read the guideSprayer sprays on its own or will not stop spraying
A sprayer that will not stop usually has the shut-off lock engaged. Squeeze the handle fully, disengage the lock, and release. If it still will not seal, the shut-off needs cleaning or replacement.
Read the guideSprayer turns on but will not spray
If the pump runs but no liquid sprays, the tank may be empty, the shut-off or nozzle is clogged, or the pump has not primed. Check the level, clean the shut-off and nozzle, and give it 30 seconds to prime.
Read the guideHow to unclog a sprayer nozzle
Relieve pressure, remove the nozzle tip, and soak it in warm soapy water. Clear the orifice with a soft brush or toothpick, never metal.
Read the guideBad spray pattern or low spray volume
A distorted pattern or low volume is almost always a clogged nozzle or dip-tube filter. Clean both, re-pressurize, and test.
Read the guideSprayer tank is leaking: repair or replace
Leaks at fittings (hose, pump base, fill cap) can usually be fixed with parts. A crack in the tank wall itself cannot be patched safely and means the tank must be replaced.
Read the guideBattery sprayers
Battery sprayer will not turn on even with a full charge
A full battery but no pump usually means an overheated protection circuit, chemical residue locking the pump, or a failed pump head. Cool it down, reseat the battery, flush the pump, then replace if needed.
Read the guideBattery and charger troubleshooting quick guide
Most battery issues are a depleted battery, an unpowered or out-of-range charger, or an end-of-life pack. The charger LED tells you which: solid red is charging, solid green is full, blinking red is too hot.
Read the guideHow to manually prime your battery-powered sprayer pump
When a battery sprayer is new or has sat unused, trapped air can stop water flow. Prime the pump once with a garden hose and it self-primes after that.

How to identify and order replacement parts
Identify your model number first, then the exact part you need. Shop genuine parts online, or call with your model number and a photo and we will match the right part.
Read the guideHow to order a replacement pump assembly or Pump Zero head
When the pump motor fails, the pump assembly may need replacing. Rule out battery, charger, and priming issues first, then call with your model number.
Read the guideHow to replace a damaged hose, wand, or backpack harness
Hoses, wands, and harness straps are user-replaceable. Match the part to your model number, then swap it out and test with plain water before using chemicals.
Read the guideWhere to find the item number on your product
The item number (also called model number or item code) is printed on the product label, packaging, or instruction manual. Most FGI item numbers are six digits, such as 190328. Some licensed-brand models add letters in front, such as DXSP190681.
Read the guideHow to find your sprayer's instruction manual
Every FGI sprayer has a digital manual. Identify your model number, then use the manual finder on our Support page or email us and we will send the matching PDF.
Read the guideHow to file a warranty claim
If your sprayer is defective and within the warranty period, the fastest way to start a claim is the online warranty form. Have your proof of purchase, a photo of the damage, your model number, and the chemicals used ready.

Sprayer cleaning and maintenance: keep your sprayer working
Most sprayer failures come from dried chemical residue. Rinse the tank and flush clean water through the hose and nozzle after every use, then store between 40 and 104 degrees F.
Read the guideULV17 fogger: what chemicals can and cannot be used
The ULV17 cold fogger is for water-based and water-soluble products only. Never use oil-based chemicals, flammable solvents, or aerosol propellants; they damage the unit and void the warranty.
Read the guideHow to maintain your Wildfire or SmokeChaser firefighting backpack pump
Flush with clean water after every use, oil the pump shaft gland nut, check the hose and nozzle, and winterize with automotive anti-freeze so the pump is ready in an emergency.
Read the guideWildfire and SmokeChaser product information
The Wildfire OT4-N is a 5.5-gallon poly-tank hand-pump fire backpack; the SmokeChaser Chief (190790) uses the FEDCO FPG100 pump. Both are for water and water/foam retardants only.
