Find out why your toilet keeps clogging

Get to the bottom of what is causing your toilet to clog once and for all. There are a few reasons your toilet keeps clogging. The following reasons could help you put down the plunger for good! Plunging is only a temporary fix so it’s important to find the root cause of the clogs.

Here are some common scenarios that might explain your returning toilet clogs.

Old toilet

If your toilet is older, it may not be able to handle a lot of flushes. By upgrading your toilet, you can ensure it is working properly and is updated to current standards. Newer toilets are designed to flush with a significant reduction in water usage while still clearing the toilet bowl completely.

Valve issues

Check the fill valve to ensure it is working properly. The fill valve is a mechanism inside the toilet tank that ensures there is enough water to flush. When the tank doesn’t fill with enough water, clogs become more common.

Flapper not opening completely

The flapper is the part of your toilet that lets water flow from the tank on the back down into the toilet bowl, creating the flush. If the flapper doesn’t fully open it won’t release enough water and you’ll get a weak flush. Clogs are common in toilets with a weak flush.

To fix it adjust the chain in the tank that connects the flapper to the flush handle. That way, the flapper opens completely when you flush.

Pipe blockages

Sometimes you can have a block in the pipes beyond the toilet. These blockages are most likely caused by flushing things that shouldn’t be flushed like a toothbrush or razor that fell into the toilet. These items will slowly be collecting debris and ultimately cause a clog.

Other common things people flush – sometimes accidentally – that cause clogs include:

  • Feminine products
  • Facial tissues
  • Cotton swabs/Q-tips
  • Dental floss
  • Diapers

Sewage line issues

A major sewer line problem somewhere in your neighborhood could be the reason why your toilet keeps clogging. Broken pipes, tree roots growing into the sewer line, or corroded metal pipes are all common causes of sewer line issues. There isn’t much homeowners can do to prevent these types of damage. However, regular sewer line maintenance and inspections can help uncover small issues before they become big, expensive problems.

Plumbing vent issues

If your plumbing vent is blocked or damaged you can get a clog. The plumbing vent removes gas from the plumbing system and helps the pipes maintain proper pressure. If your plumbing vent was damaged or is being blocked, this could cause the toilet to flush with little force.

Something stuck in the trap

The “trap” is an S-shaped tube that separates your toilet from the drain line (and keeps nasty sewer gases from getting into your home). If something unflushable was flushed down the toilet, it could be stuck in this trap. Each time you flush, more debris gets wrapped around this object, eventually leading to a clog.

A plunger can solve the problem by sending all the debris down the sewer drain, but the object stays in the trap because its shape makes it difficult to get through the S-curve.

To fix this, you must take the toilet off the floor and get to it from the bottom. This is a pain, so make sure you’ve eliminated other possible causes. Many people would rather call a plumber because mistakes can lead to bigger problems and higher costs.

If you decide to pursue this task on your own, make sure you replace the wax ring on the bottom of your toilet if you remove the toilet from the floor. This is the seal that keeps wastewater from leaking into your home.

If all else fails …

You’ll probably have to pull up the toilet. This job will take several hours. The steps involve turning off and unhooking the water supply, partially disassembling the toilet, and unscrewing it from its mounting ring. At that point, you can usually get at the problem. Be sure to buy a new wax ring and new mounting bolts to reseal the toilet base.

Remember, if other drains in your home are plugged, or if water comes up through them, the problem is probably farther down in the main drain pipes and usually out of easy reach.
