What Customers Say About Our Sewer Services in the Bay Area

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 San Francisco Residents
What is Trenchless Sewer Line Repair?
Trenchless sewer line repair is a non-invasive method that allows for sewer line replacement or repair without the need for extensive digging. It uses small access points to insert new pipes or fix damaged sections, minimizing disruption to your property.
When should you replace the Sewer Line?
You should consider replacing your sewer line if it is frequently clogged, shows signs of significant damage, or is made from outdated materials like clay or cast iron. Age, persistent leaks, and recurring backups are common indicators.
How do you know if a sewer line needs to be replaced?
Signs that your sewer line may need replacement include frequent clogs, foul odors, slow drains, or water pooling in your yard. A video camera inspection can help identify significant damage or deteriorating pipes that require replacement.
How long does it take to replace the main sewer line?
Replacing a main sewer line typically takes 1 to 3 days, depending on the method used (trenchless or traditional) and the complexity of the repair. Trenchless methods generally take less time than traditional excavation.
How much does a new sewer line cost?
The average cost of a new sewer line ranges from $2,500 to $20,000, depending on factors such as the replacement method, pipe material, and the extent of damage. Trenchless options typically cost more due to the advanced technology and minimal disruption they offer.
How often should sewer lines be replaced?
Sewer lines should be replaced every 50 to 100 years, depending on the materials used and the condition of the pipes. Regular maintenance and inspections can help extend the life of your sewer system.
