Something we encounter every day are complaints of no water or very low water flow from various items in the dental unit. Lack of water flow from any part of the dental unit is almost always due to a clog. Clogs will happen. No matter how many filters you have, what type of treatment system you use, debris can get into the water lines. When dealing with the water that travels through dental units, this is a reality. How do you determine if it is a clog and not something else? No flow at all could be a clog or a failed valve. If, however, you get good initial flow but it rapidly falls of to nothing (or almost nothing) this is classic clog behavior.
A good rule for troubleshooting a delivery unit or any piece of dental equipment is to “isolate” the problem. If you systematically rule out the “working” items, you will end up isolating the problem so that you can take the appropriate corrective action.

If you have made sure that the compressor is on and that water is available to your unit from either a public water source or bottle unit, check to see whether you are getting water to the handpieces. Now that we’ve learned the basic technique of tracing the lines, here’s how to perform the same checks if you have no water to one of the handpieces:
If you are not getting sufficient flow to any of the handpieces:
Regular dental unit maintenance and controlling the water quality with filters or self-contained water system will keep things flowing in your practice.
