Toilet Bowl Not Filling? Try This



The toilet is usually the #1 worry when it comes to bathroom plumbing. When your toilet is functioning properly, there should be no issue with the bowl filling back up with water. However, if you start to notice your toilet bowl not filling, this may indicate there could be an issue with your plumbing. Some of the most common causes of low toilet bowl levels include a partial clog, insufficient tank water, a blocked vent pipe or a cracked toilet.

Adjust Toilet Bowl Water

In order to see if your toilet is clogged, pour five gallons of water into your bowl and see if it backs up. If the water remains in the bowl, then your toilet is probably partially clogged. Try to unclog the toilet using a plunger or closet auger.

To diagnose insufficient tank water, lift open your toilet tank cover and check to see that the water level is one inch below the overflow tube. If the water isn’t high enough, adjust the height of float valve, which regulates how high the tank fills with water.

Clogged Vent Pipe

The vent pipe replaces the air that’s lost in the rush of water that occurs when you flush the toilet. However, if there’s a partial or complete blockage in the vent pipe, the movement of water completely stops. If you hear gurgling sounds in your pipes, then you likely have a blocked vent pipe. Depending on whether you’re willing to climb on the roof to tackle this, you may decide to unblock the vent pipe on your own or contact On Time Elmer for help.

Cracked Toilet Bowl

This one’s pretty easy – if you see water surrounding the base of your toilet and cannot pinpoint the cause, there’s probably a crack in your toilet bowl. Since there’s no reliable way to repair a toilet bowl crack, you’ll need to replace it. Need help with toilet installation? Bathroom plumbing is another service that we can help you with.
