Fix the water level in your urinal for best results.

Urinals are used in commercial settings such as restaurants and office buildings. If the water level in your urinal is too high or too low, you can adjust the level to get it back where it needs to be. If the water level is too high, you could overflow the urinal and cause damage to the bathroom. Changing the water level in your urinal is not a very difficult task. You can do it with minimal hassle and little knowledge of plumbing.
