What Does a Bubbling Toilet Indicate? What Does a Bubbling Toilet Indicate?

A bubbling toilet could be an indication that you need a plumbing repair. The problem may be a simple one.

Check the Flapper

There is a flapper on the inside of the tank that lets water in and out. If it doesn’t open enough, then air pockets may be getting into the toilet. Adjust the chain going to the flapper and see if that solves the problem.

Clear Any Clogs

There is a vent pipe in the plumbing that allows air to be discharged from the system. Check the roof vent and around fixtures. Using a plumbing snake in the drain may remove the clog. It is also possible that during cold weather, frost may be building up in the pipe, and you may need a larger pipe.

Examine the Toilet for Cracks

If there is a crack in the toilet, it can let in air. Check the toilet thoroughly for any sign of a fracture. If you find a crack, you may need to replace the toilet.

Adjust the Refill Valve

There is a pipe that comes out of the refill valve. If it is not seated well at the overflow pipe or the rate it refills not set correctly, it will let air into the toilet. Adjust the ballcock screw or the hose and see if that fixes the problem.

If these troubleshooting steps don't fix the problem, then you may need to call a professional plumber.
