Had the plumber Daniel come to my condo today for a clogged toilet. He spent almost two hours snaking with a camera my drain and pulled out a huge clog of tree roots. He knew exactly what he was doing and did a wonderful job. I would recommend this company very much.
Ron K.

Great, reliable, and timely service at a reasonable price. I shopped around quite a bit before landing on CPI. Their rates were competitive, they responded promptly, and their plumber fixed a few issues quickly and without much fuss. I’ll definitely be calling them again the next time we have issues!
Allan Huynh

CPI Service was sent to my home by my condominium association. They agreed to a very early morning appointment and the gentleman arrived exactly on time. He went through the problem very methodically to see where the problem was. Something that no one else could figure out was taken care of in half an hour. I would very definitely recommend them.

Sewer Line FAQs for Fremont

What is a Sewer Line?
A sewer line and a drain line serve different purposes: Sewer Line: Carries all wastewater and waste from your home to the public sewer system or a septic tank. Drain Line: This refers to the pipes that carry water away from sinks, tubs, and toilets to the sewer line. While both systems are part of your home's plumbing, the sewer line handles the heavier waste, while the drain lines only carry water.
What is the Difference Between a Sewer Line and a Drain Line?
A sewer line and a drain line serve different purposes:
- Sewer Line: Carries all wastewater and waste from your home to the public sewer system or a septic tank.
- Drain Line: This refers to the pipes that carry water away from sinks, tubs, and toilets to the sewer line.
How Do You Know if a Sewer Line Needs to Be Replaced?
Several signs may indicate your sewer line needs to be replaced:
- Frequent Clogs: If you notice clogs occurring regularly, even after drain cleaning, it may be a sign of a damaged sewer line.
- Foul Odors: Unpleasant smells in your home or yard could indicate that your sewer line is leaking.
- Water Backups: If your toilet or drains frequently back up, it could be a result of a sewer line blockage or damage.
- Slow Drains: Drains that are slow to clear, even after plunging, often signal a sewer line issue.
How Long Does It Take to Replace a Main Sewer Line?
The time it takes to replace a main sewer line can vary depending on the method used:
- Traditional Sewer Line Replacement: Typically takes 2–3 days due to excavation and manual labor involved.
- Trenchless Sewer Line Replacement: This method can usually be completed in 1–2 days, as it requires less digging and is faster.
How Much Does a New Sewer Line Cost?
The cost of a new sewer line replacement can vary depending on several factors:
- Location of the Problem: The distance from your home to the sewer main and the complexity of excavation.
- Method Used: Traditional methods may cost more due to the required excavation, while trenchless methods are generally more cost-effective.
- Type of Pipe Material: The material used for the new sewer line (e.g., PVC, cast iron) can affect the price.
How Often Should Sewer Lines Be Replaced?
Typically, sewer lines can last anywhere from 30 to 50 years, depending on the material used (e.g., clay, cast iron, or PVC). However, certain factors such as tree root intrusion, corrosion in older pipes, and damage due to settling soil or shifting foundation can shorten the lifespan. Regular and timely inspections can help identify any issues early and extend the lifespan of your sewer line.
Is Trenchless Sewer Repair in Fremont the Right Choice?
Trenchless sewer repair is an excellent choice for many Fremont homeowners. Here are the main benefits:
- Minimal Disruption: Since the process requires little digging, your yard, driveway, or landscaping will not be damaged.
- Cost-Effective: Although initial costs may seem higher, trenchless repair reduces the need for excavation, which can make the overall project more affordable.
- Faster Completion: Trenchless methods allow for faster repairs, often completed within 1–2 days.
- Long-Term Durability: The materials used in trenchless sewer repairs are highly durable and can last for many years.
