What Cupertino Customers Say About Our Sewer Services

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.

What to Do When a Sewer Line Breaks in Cupertino?
If you suspect or discover a broken sewer line in Cupertino, it’s important to act quickly to minimize damage and avoid health risks. Here’s what you should do:
- Stop Using Water: Immediately stop using water in your home to prevent further sewage backup and flooding. This includes toilets, sinks, showers, and washing machines.
- Contain the Area: If possible, avoid the affected area to prevent exposure to raw sewage. Keep pets and family members away from the site.
- Call a Professional: Contact CPI Service immediately for a professional inspection. We offer fast, reliable emergency services and will send a licensed plumber to assess the damage and provide the best solution for repair or replacement.
- Do Not Attempt DIY Repairs: Sewer line repairs require specialized equipment and knowledge. Attempting to fix it yourself can lead to further damage and health risks.
What Are Common Sewer Line Problems in Cupertino?
Homeowners in Cupertino often deal with various sewer line problems, ranging from persistent clogs to serious pipe damage. Addressing these issues early can prevent costly repairs and extensive property damage. Here are the most common sewer line problems you might encounter in Cupertino:
- Recurrent Clogs and Obstructions: Recurrent clogs are a common issue in sewer lines, typically caused by the buildup of grease, soap, debris, or even tree roots. These blockages can worsen over time and lead to pipe bursts or backups. If you’re experiencing slow drainage or frequent clogging, it’s important to have a professional plumber inspect your system before it leads to more expensive repairs.
- Leaking Pipes and Cracks: Leaking pipes are a serious problem that can go unnoticed until it’s too late. Even small cracks in your sewer pipes can allow water to escape, potentially flooding your yard or weakening your home’s foundation. These leaks can also cause foul odors to seep into your home. Quick identification and repair are essential to avoid further damage, and CPI Service provides prompt, reliable repairs for Cupertino homeowners.
- Unpleasant Odors and Slow Drains: If you’ve noticed unpleasant sewage odors or slow drains in your home, it’s often a sign that your sewer line is clogged or damaged. Left unchecked, this can lead to full blockages or even sewage backups. Fast intervention can prevent more serious damage, and CPI Service is equipped to resolve these issues swiftly for Cupertino residents.
- Tree Root Intrusion: In Cupertino, tree roots are a common culprit in sewer line damage. As trees grow, their roots often seek out the moisture in sewer pipes, causing cracks or blockages. Over time, roots can fully invade your pipes, leading to serious blockages or even pipe collapse. CPI Service specializes in removing roots and restoring the full functionality of your sewer system, ensuring that your property’s landscaping isn’t affected in the process.
- Sewer Line Backups and Flooding: Sewer line backups are emergencies that require immediate attention. When there’s a blockage or a major failure in the sewer system, wastewater can flood your home or yard. This can cause extensive damage and create health hazards. CPI Service offers 24/7 emergency repairs to quickly address these backups and prevent further issues from developing.
- Sagging Pipes: When pipes begin to sag due to soil shifts or improper installation, it can cause drainage problems and blockages. If left unaddressed, sagging pipes can lead to a full system failure. CPI Service provides efficient solutions to re-align and repair sagging pipes, restoring proper flow and preventing future issues.

Sewer Line FAQs for Cupertino
How Much Does It Cost to Replace a Sewer Line in Cupertino?
The cost to replace a sewer line in Cupertino typically ranges from $3,000 to $15,000, depending on factors like the method (trenchless or traditional), the length of the line, and the condition of your property.
Does Homeowners Insurance Cover Sewer Line Replacement?
Generally, homeowners insurance does not cover sewer line replacement for issues such as blockages, wear, or tree root damage. However, some policies offer sewer backup coverage, which may cover repairs caused by flooding or heavy storms. It's best to check with your insurance provider for specific coverage details.
Why is Replacing a Sewer Line So Expensive?
Replacing a sewer line can be costly due to several factors, including labor, materials, and excavation requirements. Traditional methods are often more expensive due to the disruption and extensive digging involved, while trenchless methods tend to be more affordable and less invasive. However, both approaches require significant expertise and specialized equipment, and the complexity of the job, such as the length of the line or obstacles on the property, can add to the cost.
Can a Homeowner Replace a Sewer Line?
While it’s technically possible for a homeowner to replace a sewer line, it is strongly recommended to hire professionals like CPI Service.

Licensed professionals ensure the work is completed properly, avoiding potential mistakes and costly repairs down the road.
What is the Average Lifespan of a Sewer Line?
A sewer line typically lasts between 30 to 50 years, depending on the material used (PVC, clay, or cast iron). Regular inspections and timely maintenance can help extend its life. Factors such as tree root intrusion and shifting soil can shorten its lifespan.
