Here are some ways sewer pipe material impacts the inspection:
1. Durability and Longevity
Cast Iron: Often used in older homes, cast iron is durable but can corrode over time. SDI Inspectors check for rust, cracks, and signs of wear that might affect the sewer’s function.
PVC or ABS (Plastic): Modern materials like PVC or ABS are resistant to corrosion and generally considered durable, but our inspectors will look for proper installation and any signs of cracks, especially at joints.
Clay or Orangeburg Pipes: These materials were commonly used before the 1970s. Clay is prone to root intrusion, while Orangeburg (a fiber-based material) deteriorates over time. Both can signal potential issues in older homes. If your home was built before the 70's, contact us to schedule an inspection.
2. Potential for Blockages
Older materials, such as cast iron or clay, are more susceptible to tree root intrusion or blockages from debris due to their porosity or connections. SDI Inspectors may recommend a sewer camera inspection to check for obstructions.
3. Environmental Impact and Code Compliance
Materials like lead or outdated pipes may not meet modern building codes, and our SDI inspectors may flag these for replacement. Compliance with current codes ensures the home is safe and environmentally sound.
4. Structural Integrity of the System
Sewer pipes can settle or shift over time, particularly if the material is brittle or prone to cracking, like clay or Orangeburg. We will look for signs of sagging or misaligned pipes, which can cause leaks or backups.
5. Water Quality and Safety
Older sewer lines, especially those made of lead or other metal prone to corrosion, can leach harmful substances into the water system, raising health concerns. Inspectors will check for leaks or contamination risks.
6. Repair and Replacement Costs
If we find your sewer system is made from outdated or damaged materials, we will highlight the potential repair or replacement costs. This can influence the overall home inspection report and affect negotiations between buyer and seller.
The condition and type of sewer material can influence the safety, functionality, and long-term value of the property. Schedule an Inspection today - online or call: (480) 345-9200
