What Causes Your Toilets to Back Up Into Showers and Bathtubs?
When wastewater from your toilet finds its way into your shower or bathtub, it’s often due to a blockage or disruption somewhere in your plumbing system. There are several common culprits that could be causing the issue.
Clogged Drains and Pipes
In our experience, clogged drains are often the culprit behind frustrating plumbing issues. In fact, we’ve identified some of the most common causes of clogged drains that can lead to problems like toilet backups. If you’re experiencing a toilet backing up into your shower, it’s likely due to a clog in the drain line.
Sewer Line Blockages
A blockage in the main sewer line is one of the most common reasons for a toilet backing up into a shower. When the main line is clogged, wastewater can’t flow freely and will find the nearest escape route, which is often a shower or tub drain. This can be caused by debris, grease, or tree roots infiltrating the sewer line.
Tree Roots Invading Pipes
Tree roots can wreak havoc on your plumbing systems by growing into your underground pipes in search of water. Once inside the pipes, the roots expand and block the flow of water, leading to backups in your plumbing system. This can be particularly problematic if your home has older pipes or if there are large trees close to your sewer lines.
Flushing Non-flushable Objects
Flushing anything other than toilet paper and human waste can cause serious plumbing issues. Items like sanitary products, wet wipes, and even paper towels can become lodged in your pipes, creating a blockage that forces wastewater to back up into your shower.
Improper Venting
Plumbing systems rely on venting to allow air to enter the pipes, which helps wastewater flow smoothly. If your plumbing vents are blocked or improperly installed, the pressure in your pipes can cause water to flow in the wrong direction. This may lead to backups in your shower or bathtub.
Build-Up of Hair and Grease
Grease from the kitchen and hair from the bathroom can build up in your pipes over time, creating stubborn clogs. Hair clogs are especially common in bathroom drains, while grease clogs typically form in kitchen drains. If these clogs occur close to the main drain line, they can cause water to back up into other parts of the house, such as your shower.
Overflowing Septic Tank
If your home is on a septic system, an overflowing or full septic tank can cause sewage to back up into your plumbing fixtures, including your shower. When the septic tank is full, the wastewater has nowhere to go, leading to backups throughout the home.
Damaged or Collapsed Pipes
Over time, pipes can become damaged or even collapse due to age, shifting soil, or external pressure. A collapsed pipe will prevent water from flowing properly, leading to backups in your plumbing system. This is a more serious issue that often requires professional inspection and repair.
What to Do When Your Toilet is Backing Up Into Your Shower
Using a Drain Snake (Auger)
If you’re experienced with using a plumbing snake, it can be effective in clearing blockages. Insert the snake into the main cleanout and gently push through the clog. If you encounter resistance, retract and try again, working the snake back and forth.
Important: Using a snake improperly can cause damage or make the issue worse. Only use a snake if you’re experienced and have the correct tool. Avoid excessive force to prevent injury or complications. If unsure, it’s best to call a professional.
Calling a Professional Plumber
When your toilet backs up into your shower, it’s often a sign of a bigger plumbing issue. If you’re not familiar with plumbing, trying to fix it yourself can cause more harm than good.
A professional plumber has the expertise and equipment to diagnose and fix the problem correctly. They can clear blockages with specialized tools and perform a video sewer camera inspection to detect underlying issues. If needed, they’ll perform services like hydro jetting, pipe repair, or sewer line cleaning to get your plumbing system working properly again. By calling a plumber, you’ll avoid costly mistakes and have peace of mind knowing the job is done right.
What NOT to Do When You Have a Backup
Don’t use Chemical Drain Cleaners
It may seem like an easy solution, but chemical drain cleaners are not effective for large or deep clogs like the ones that cause a toilet to back up into a shower. Most chemical cleaners are designed to work on small clogs in the P trap, but the kind of clog causing this issue is likely much deeper in your drain line. Using these chemicals can cause damage to your pipes, especially if they don’t solve the problem and sit in the pipes for too long.
If you’ve already used a chemical drain cleaner and it didn’t work, be sure to inform your plumber when you call for professional help. This is crucial for their safety, as the chemicals can cause burns or other injuries if they aren’t aware and don’t take the proper precautions. Always let your plumber know if you’ve attempted any chemical treatments before they arrive.
Don’t Continue Using Plumbing Fixtures
Flushing toilets, running sinks, or using the washing machine can add more water to the system, which could lead to more waste backing up into your shower or even flooding in other areas of your home. When dealing with a plumbing backup, it’s best to stop using water fixtures until the problem is resolved.
Avoid DIY Methods That Could Worsen the Problem
Many homeowners attempt DIY methods to fix a plumbing backup, like using plungers, snakes, or even more aggressive techniques. While some of these approaches might work for minor clogs, using them incorrectly can cause significant damage. For example, improperly using a drain snake could scratch or break pipes, leading to leaks or further blockages. If you’re not experienced with these tools, it’s best to leave the job to a professional who can properly assess the situation and fix it without causing additional damage.
