Causes of Toilet Water Coming Up in Tub

There are four main causes of toilet water coming up in a tub:

  • A clog in the drain line between the toilet and the tub
  • A clog in the overflow drain in the tub
  • A leak in the wax seal between the toilet and the floor
  • A crack in the drain line or the tub

Let’s take a closer look at each of these causes.

A clog in the drain line between the toilet and the tub

The most common cause of toilet water coming up in a tub is a clog in the drain line between the toilet and the tub. This can happen if something gets stuck in the drain, such as a piece of toilet paper, a hairball, or a small toy.

When the drain line is clogged, the water from the toilet can’t drain properly, and it will start to back up into the tub. This can cause the water level in the tub to rise, and it can even overflow onto the floor.

A clog in the overflow drain in the tub

Another common cause of toilet water coming up in a tub is a clog in the overflow drain. The overflow drain is located at the top of the tub, and it’s designed to prevent the tub from overflowing if too much water gets in it.

If the overflow drain is clogged, the water from the tub can’t drain properly, and it will start to back up into the toilet. This can cause the water level in the toilet to rise, and it can even overflow onto the floor.

A leak in the wax seal between the toilet and the floor

A leak in the wax seal between the toilet and the floor can also cause toilet water to come up in the tub. The wax seal is a ring of wax that creates a watertight seal between the toilet and the floor.

If the wax seal is damaged or worn out, it can allow water to leak from the toilet into the tub. This can cause the water level in the tub to rise, and it can even overflow onto the floor.

A crack in the drain line or the tub

Finally, a crack in the drain line or the tub can also cause toilet water to come up in the tub. If there is a crack in the drain line, the water from the toilet can’t drain properly, and it will start to back up into the tub.

If there is a crack in the tub, the water from the tub can leak into the toilet. This can cause the water level in the toilet to rise, and it can even overflow onto the floor.
