Why Do My Home’s Sewer Lines Crack?
A number of different environmental factors can contribute to cracked sewer lines. Some of the most common include:
- Tree roots. Roots are powerful and often reach out towards sewer lines in search of water, cracking those lines as they grow.
- Blockages such as grease or foreign objects. When a sewer line is blocked, the pressure that builds up behind the blockage can cause damage to the pipe.
- Weather. On occasion, frozen ground causes sewer lines to crack.
- Corrosion. Over time, the material from which sewer pipes are constructed will degrade, causing those pipes to crack and collapse.
If you are experiencing a noticeable decrease in flow when you flush your toilet and suspect cracked sewer lines may be to blame, it is important to hire a professional plumber with sewer line repair experience to examine the situation and make recommendations.
