If you’re seeing urine where it shouldn’t be—outside the bottle, in the base, or seeping toward the solids bin—a water test can help diagnose what’s going on.
It’s not normal for urine to bypass the bottle. If this is happening, please contact us so we can troubleshoot and resolve the issue quickly.
Step 1: Prepare the Setup
The first step in a successful water test is to make the drainage system visible.
-
Remove the drawer, but leave the urine bottle installed.
-
The bottle will sit slightly lower without the drawer, but it will still engage with the drain spout on the bottom of the toilet.
This lets you clearly observe where the water goes as it enters the toilet.
Step 2: Simulate Liquid Flow
Now it’s time to pour water into the bowl to simulate real use.
-
Slowly pour water into the front of the bowl, where urine would typically flow.
-
Then, pour water near the back of the bowl with the trap door closed, to test less ideal but possible splash scenarios.
Tip: This is much easier with two people!
One person can pour water while the other uses a flashlight to watch the internal flow closely.
If everything is working correctly:
-
All liquid should flow into the urine bottle.
-
No drips, puddles, or trickles should appear outside the bottle or base.
Step 3: Test with the Trap Door Open
Let’s test a worst-case scenario: when excess liquid hits the back wall of the bowl with the trap door open.
-
Pour water into the rear of the bowl again.
-
Observe where the liquid goes.
Expected behavior:
-
Most urine hitting the rear separator will either trickle safely into the solids bin,
-
Or, in rare cases, small amounts may flow to the front lip of the bin.
This is intentional—OGO™ toilets are designed to minimize leakage even under less-than-ideal usage conditions.
