Your bathroom experiences a lot of traffic. It's one of the most used rooms in your home. That's why properly functioning plumbing is a necessity. Dirty water backing up through your tub's drain is unsightly and unsafe. Sometimes it even smells, and that can be incredibly worrisome.

Let's explore the possible reasons this could be happening to your home:

1. Failing System

Your system could be failing due to age or poor workmanship. It's also possible that the drain hasn't been maintained properly. The way the lines are connected, you might have a poor seal. If the seal is damaged, dirty water could easily back up into your bathtub and other fixtures around your home.

2. Tree and Bush Root Interference

It's not uncommon for your bathtub's drain line to become crowded with tree roots. Tree roots can slowly encroach on your sewer system, causing clogs and damage. Roots can even make it difficult for water to reach your home. If you notice roots in your sewer service area, you need to contact a professional to clear out the root damage and make your sewer service functional again.

3. Use of Multipurpose Pipes

It's important to know that a multi-line pipe drain is not right for every plumbing situation. The simple reason is that this type of pipe allows water to flow in different directions. If your home uses these pipes in your bathtub's drain, you will likely experience drain backups, especially during heavy rains, as they will have to handle storm water.

4. Clogged Drains

When you notice that your bathtub's water is coming back up, it's time to check your drain. Your drain should be carefully inspected and cleaned by a plumber. Clogged drains are usually the result of hair, soap scum, and various other buildups. You might notice that your bathtub's water is coming back up if you see this buildup around the drain or if you notice a slow drain when you take a shower.

Fixing Clogged Drains

If you have clogged drains, you should immediately call a plumber. The sooner you get your drains cleared and cleaned, the better. If you put it off, the clog is likely to get worse. It could even reach other parts of your plumbing system.

Here's what you can try:

1. Baking Soda and Vinegar

Simply pour half a cup of baking soda down your drain, followed by half a cup of vinegar. The reaction will create a bubbling foam. Let this sit for a few minutes, then flush it with boiling water.

2. Snake Drain Cleaning Tool

A drain cleaning tool can often work where other methods have failed. As you snake the drain, you will loosen and remove trapped debris.

3. Plunger

The trick to using a plunger is to have it seal tightly to the drain and create a vacuum. Using a powerful, fast blast of air will force the clog loose.


Most of the time, dirty water will back up from your drain because of clogs. You will be able to fix this right away if you identify the problem and take action. Don't let things get worse, as it could cost you more in the long run.
