What Causes a Sewer Backup?

Sewer backup is one of the most frustrating plumbing problems homeowners face and struggle to deal with because of inconvenience and expensive repairs. However, it is also one of the primary aspects of home maintenance to keep your household running smoothly. Prevention is better than draining your savings on expensive repairs. Knowing the different causes of a sewer backup can help you prevent the problem in the future. Also, consulting with Modesto plumbers can help you detect the reasons before the problem escalates.

Here Are the Causes of a Sewer Backup:

1. Plumbing Clogs

If you notice slow drainage in the bathroom, sinks, or kitchen or unusual gurgling sounds, it may indicate the start of a clogged drain. Severely clogged drains affect sinks, toilets, showers, bathtubs, dishwashers, and washing machines, leading to sewer backups. Consulting with experts in drain cleaning in Modesto can help fix the problem.

How Does a Drain Gets Clogged?

If you flush unwanted objects down the drain, your drains will get clogged and affect the plumbing system. Stop putting the following objects down the drain:

  • Grease and oils
  • Hair
  • Coffee grounds
  • Feminine hygiene products and baby wipes
  • Paper products
  • Food waste
  • Tiny toys
  • Dental floss and cotton swabs

2. Tree Roots

Tree roots growing near your underground wastewater system are a potential risk of clogging your sewer. Tree roots can infiltrate your pipes, causing holes or wrapping around the sewer lines, affecting the smooth functioning of the system. Tree roots cause blockage in the pipes preventing the smooth flow of sewage to the main system.

3. Illegal Plumbing Connections

You may not realize the severity of installing illegal plumbing connections unless it starts showing drastic effects on your home plumbing system. For example, if you have installed a sump pump to the line in your sewer system, it can cause blockages in your house. Consult a plumber to check the accuracy of other installations.

4. Damaged Sewer Lines

It is necessary to schedule quarterly inspections to check the sewer lines because they may suffer damage due to wear and tear. If you live in an older house, the chances are your system has damaged pipes, no matter how durable they are.


House maintenance is imperative to prevent expensive damage to your house. Watch out for these primary causes leading to sewer backups. If frequent sewer backups occur in your house, it may indicate an underlying problem. It may be tempting to fix the problem using DIY solutions; however, it can cause more damage. Consulting an expert is the best decision because professionals know where to look without wasting time. Water damage experts have cutting-edge equipment to detect the primary cause and employ effective fixes.
