Urinal blockages rarely happen overnight. They are usually the result of a buildup over time. Unlike toilet paper blockages, urinal blockages are often chemical or structural.
Ironically, trying to keep a urinal clean can block it. if cleaning staff pour bucket water into a urinal, debris (mop strings, grit, dirt) gets washed into the trap. Also, using excessive urinal screen cleaner gel can congeal in cold pipes.

Use a flathead screwdriver or a dedicated grate removal tool to pop off the metal cover. Clean any hair, debris, or trash trapped directly underneath the grate. Step 3: Attempt Mechanical Clearing (The Auger) blocked urinal
Do not use Drano. Use a phosphoric or hydrochloric acid based (available at hardware stores).
The drain makes bubbling noises during or immediately after a flush cycle.
If your blocked urinal is currently overflowing as you read this—stop reading. Go shut off the water supply valve behind the unit, mop up the floor, and call your local plumbing service immediately. Urinal blockages rarely happen overnight
This works well for breaking down soap scum and partial organic blockages. Pour a large pot of boiling water directly into the urinal. Add a generous amount of liquid dish soap (grease cutter). Let it sit for 15 minutes. Flush the urinal. Method 2: Baking Soda and Vinegar (For Chemical Clogs) The fizzy reaction can help break up soft scaling. Remove any standing water. Pour 1 cup of baking soda into the trap. Follow with 1 cup of white vinegar. Cover the drain opening to force the foam downward. Wait 30 minutes, then flush with hot water. Method 3: Chemical Urinal Descalers (For Uric Acid)
Slowly flush the system with warm water to wash away the dissolved minerals.
When plunging fails, the clog is likely deep within the trap or waste pipe. Do not use a standard toilet auger, as its large metal coil can crack the delicate porcelain of a urinal. Use a dedicated , which features a narrower spring-loaded cable and a protective rubber boot to shield the ceramic. Ironically, trying to keep a urinal clean can block it
If you notice damp drywall, puddling water beneath the fixture, or water leaking through the ceiling below, the pipe may have cracked due to heavy scale expansion or aggressive snaking.

While intended to freshen, if not replaced regularly, they can slip into the drain, causing an instant blockage.
Over time, loose hair washed down the drain binds with the sticky uric scale, acting like a net that catches other passing debris.
