How to Fix a Slow Draining Urinal

Urinals are convenient. They allow guests of any business to go into the restroom and out in a couple of minutes. Bonus, they’re easier to clean than toilets, and they consume significantly less water. However, if one of them becomes clogged, then you’re dealing with a slow drain. As a result, you end up with unpleasant smells and an unhygienic public restroom. Surely this is not the image you want for your business.

What are the main causes of a slow draining urinal, and what can you do to fix it?

3 Causes of a Slow Draining Urinal

Although in theory urinals only drain liquid, there are two main factors that may cause its drain to clog:

1. Mineral buildup in water

Living in Florida, you’re likely no stranger to seeing evidence of hard water everywhere: Shower liners and shampoo bottles become mottled with white stains. The same thing happens with kitchenware at the end of a cycle in the dishwasher. Water in the Sunshine State creates these unsightly stains due to its high mineral content. These minerals can stick to steel pipes. Over time, the significant buildup will cause water to drain slowly.

2. Sediment in urine

This isn’t a topic that most people talk about, but urine actually contains microscopic solid particles: skin cells, proteins, debris from the urinary tract, mucus, etc. The amount of sediment typically found in urine depends on the person’s overall health and personal hygiene. While imperceptible to the naked eye, a large amount of sediment will cause a drain to clog.

3. A combination of both

This is the most likely scenario. Unless you regularly clear your pipes, regular wear and tear of a urinal in Florida means solid urine particles and calcium deposits along the pipes; especially in the urinal’s “J Trap”.

How to Fix a Slow Draining Urinal

Fortunately, fixing a slow draining urinal is relatively simple. In fact, it’s very similar to unclogging a toilet.


  • Screwdriver
  • Plunger
  • Urinal Auger (for deep clogs)


Step 1. Use a screwdriver to remove the metal drain cover.

Step 2.  Use a plunger to unclog a blockage near the opening of the drain.

Step 3. Flush the urinal to test whether the plunger removed the blockage.

Step 4. Use a urinal auger to reach a deeper clog. When you feel it hit something solid, jiggle it around and slowly pull up the blockage.

Step 5. Flush the urinal again to make sure that you’ve removed everything that was clogging the pipe.
