Why Does the Floor Drain Overflow When the Toilet is Flushed?

When using a toilet, sometimes there may be leakage issues that affect its functionality. Next, we will introduce the reasons why flushing the toilet causes waste to overflow from the floor drain.

Why Does the Floor Drain Overflow When the Toilet is Flushed?

1. Problems with the floor drain can cause the toilet to overflow with water when flushed.

2. Issues with the drainage pipe can lead to overflow from the floor drain.

3. Problems with the installation of pipe fittings can result in overflow from the floor drain.

4. A blockage in the toilet can prevent smooth drainage.

5. If the sewage outlet of the septic tank has not been cleaned for a long time, it can lead to sewage overflowing from the floor drain.

Now, what should you do if the toilet drain is blocked?

1. First, insert the hose of a plunger into the drain and seal the outlet. Then, pour water into the drain and quickly use the plunger to create pressure, which can help clear the blockage.

2. Pour baking soda and vinegar into the toilet, then wait a few minutes. The chemical reaction between the baking soda and vinegar can dissolve blockages in the plumbing.

3. Take a piece of wood with a diameter close to that of the drainage pipe and insert it into the drain. Pour enough water into the toilet bowl and quickly move the wood up and down. This should create significant pressure and suction in the drain, helping to clear the waste.

4. Insert one end of a water hose into the drain, sealing the outlet. Connect the other end to the faucet, turn the faucet to maximum flow, and keep it flowing. The strong water pressure will help clear the blockage.
