What Is a Fimco Sprayer?

Fimco sprayers are typically used in industrial or large-scale farm settings. They're heavy-duty sprayers often attached to an all-terrain vehicle (ATV). That means that any breakdown in their functionality can result in significant disruptions to your livelihood or to your ability to feed yourself and your family.

What’s Wrong With Your Fimco Sprayer?

If there's a problem of any kind with your Fimco sprayer, the first place you should check is your owner's manual. Whether the problem is that your Fimco sprayer pump won't turn on or your Fimco sprayer is not building pressure, chances are good the manual can help.

One issue that commonly occurs is Fimco sprayers not building pressure. If this happens, you may need to clean your filter screen (which could be clogged) or clean the check valve. There may be debris in the check valve, or it may even be damaged. If that doesn't fix the problem, make sure there isn't a leak or hole in the supply line or cracks in the pump housing or line – the discharge hose could also be too long.

These are even more likely to become issues if you haven't performed routine care maintenance. After each use, you should rinse your pump with a tank neutralizer. In addition to this, be sure to always to store your sprayer indoors, away from the elements, and winterize the machine if necessary. Always use clean water and never use your sprayer to pump bleach, fuel or any other type of liquid.

If the pump won't run, the likely culprit is loose wiring or a faulty fuse. Refer to your manual to find where these are and check each one – fuses can blow from defective wiring or a voltage surge.
