Urinals are commonly found in two places: men's rest rooms and unisex rest rooms. If you are in charge of keeping a company rest room clean and in good working order, then at some point you might be faced with a clogged urinal. When this happens, stay calm. Unclogging a urinal is no different than removing a clog from any other type of drain, and can be easier to unclog than a toilet.
Remove the drain covering from the inside of the urinal by taking out the screws with a screwdriver.
Add a few inches of water to the inside of the clogged urinal.
Place a plunger over the drain inside the urinal and give it several strong thrusts. This can remove clogs that are close to the drain's surface.
Insert a drain auger cable if the plunger doesn't work. Crank the auger to insert the cable slowly.
Stop cranking when you feel the cable hit the clog. Crank a little more so the cable can attach to the clog.
Pull out the drain auger cable by cranking the opposite way. The clog will come out, too.
