Older Low Flow Toilets

If your home is outfitted with fixtures that are low-flow, then the toilet may be the reason that your toilet is constantly clogged.

Too Much TP

Avoid Excessive Use Of TP

The majority of people use eight to nine squares for each flush of toilet paper however 3 to 4 squares are enough. To stop blockages ensure that household members are encouraged to limit their use of toilet paper.

Toilet Vent Blockage

The toilets in all of your Cincinnati house are ventilated which permits the air outside to flow into the plumbing system. This helps keep sewer line odors from your living space and increases the pressure of flushing.

The blocked toilet vent makes it difficult for a toilet to keep getting blocked. Pressure drops and other issues can occur, such as the smell of sewers as well as gurgling out of the toilet, and poor drainage.


Since the entrance to the toilet vent is located at the top of the building, obstructions occur at the exterior vent opening. If you are noticing indications of a toilet that is blocked vent and your bathroom continues to get blocked, follow these steps:

  3. Utilizing your garden hose, spray water toward the exhaust. A powerful flow of water could force the obstruction to the outlet and into the sewer line. If water backs toward the roof, you can tell that the blockage isn’t clear.
  4. Utilize an auger for toilets (needs to have at minimum 20 feet long) and place it inside the vent. Rotate it until it breaks the blockage.
  5. Continue to pour water through the vent to remove the blockage. If the water is still leaking then call your plumber for assistance.
