What Palo Alto 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.

Early Signs of Sewer Line Replacement
Identifying the early signs of sewer line problems can help prevent costly damage and potential health risks. Often, these issues start small but can quickly escalate into serious plumbing emergencies if ignored. Palo Alto homeowners can protect their property, minimize disruptions, and extend the lifespan of their sewer system by staying vigilant and recognizing these warning signs.
Slow Drains and Gurgling Toilets
If you notice slow drains or hear gurgling toilets, it’s often a sign of an underlying sewer line issue. These symptoms typically indicate developing blockages caused by grease buildup, tree roots, or debris in the pipes. As clogs form, trapped air is forced out through fixtures, causing the distinctive gurgling sound and slower drainage. This usually affects toilets and bathtubs, causing water to drain more slowly in Palo Alto homes.
Sewage Odors Around the Home or Yard
A strong, foul odor near fixtures, lawns, or walls around your Palo Alto home may indicate escaping sewer gases or a hidden issue with your sewer line. Cracked or blocked pipes often release hydrogen sulfide, which creates the distinct “rotten egg” smell. This should be addressed immediately. Homeowners may notice these odors near floor drains, basement plumbing, or low-lying areas of the yard, especially after heavy water usage or rain.
Recurring Clogs in Multiple Fixtures
Frequent clogs in multiple drains, such as sinks, toilets, and showers, often indicate a blockage in the main sewer line of your Palo Alto property. Kitchen drains, floor drains, and bathtubs are common areas affected, usually due to a partial blockage obstructing the flow of wastewater. If ignored, this issue can escalate into a complete system backup, leading to flooding and significant property damage.
Sudden Drop in Water Pressure
A sudden drop in water pressure across your Palo Alto home’s fixtures may indicate cracked or shifted lateral pipes. Unlike typical leaks that cause visible drips, this issue impacts the flow consistency and can signal a more serious sewer problem. It’s essential to have it inspected promptly by a professional sewer line service to avoid further complications.
Sewage Backups or Overflow Events
Sewage backups or overflowing toilets are clear emergencies for Palo Alto homeowners. This happens when wastewater rises from floor drains, toilets, or tubs, causing visible contamination, foul odors, and disruption throughout the property. In addition to property damage, raw sewage poses serious health risks. CPI Service provides immediate cleanup and restoration to prevent both structural and biological contamination.
Increase in Water Bills
A sudden increase in your water bill may signal subsurface leaks or hidden plumbing issues in your Palo Alto home. Problems like cracked pipes or damaged sewer lines, often located underground or behind walls, could be the cause. It’s important for Palo Alto homeowners to schedule an inspection promptly to prevent wasted water and further hidden damage.
How to Prevent Sewer Line Breaks and Costly Repairs
To avoid unexpected sewer line breaks and costly repairs, Palo Alto homeowners should take proactive steps to protect their plumbing systems. Consider these preventive measures:
- Never flush wipes, grease, paper towels, or other debris down the drain.
- Have your sewer lines professionally cleaned every 1–2 years, especially in older homes or those near large trees.
- Watch for warning signs like slow drainage or unpleasant smells, and address them immediately.
Taking these steps can significantly extend the life of your sewer system and help you avoid expensive future repairs.
Advantages of Trenchless Sewer Line Replacement
Minimal Property Disruption
Trenchless sewer repair eliminates the need for extensive excavation, protecting your Palo Alto landscaping, hardscaping, and structures. This method uses small access points to repair or replace underground pipes, making it ideal for properties with established gardens, pools, or patios. Trenchless sewer replacement provides a fast, efficient, and non-invasive alternative that minimizes disruption to your property.
Faster Project Completion
Unlike traditional excavation, which can take up to a week, trenchless sewer line replacement typically only requires one to two days. This method involves less manual labor, minimal site restoration, and reduces downtime, making it ideal for Palo Alto homeowners. It accelerates both installation and cleanup, with minimal disruption to landscaping, driveways, and plumbing systems.
Cost Efficiency Over Time
Although trenchless sewer line replacement may come with a higher initial cost compared to traditional methods, it provides substantial long-term savings for Palo Alto homeowners. By reducing the need for excavation, this method cuts down on restoration costs and helps avoid recurring maintenance or repairs caused by soil disruption.
Enhanced Pipe Longevity
Trenchless technology uses advanced materials like cured-in-place epoxy liners and tough HDPE pipes to provide superior resistance against wear, root intrusion, and collapse. These modern pipes are designed to last over 50 years, giving Palo Alto homeowners peace of mind with a durable, leak-proof sewer system that offers long-term reliability.

Sewer Line FAQs for Palo Alto
What is a Sewer Line?
A sewer line is a pipe that transports wastewater and waste from your home to either the municipal sewer system or a septic tank. It’s a crucial component of your plumbing system, responsible for maintaining proper sanitation. Regular inspections, maintenance, and prompt repairs are essential to prevent clogs, leaks, or backups that could lead to more costly repairs or potential health hazards.
Does Homeowners Insurance Cover Sewer Lines?
Homeowners insurance generally does not cover sewer line replacement for issues like blockages, general wear, or damages caused by tree roots. However, sewer backup coverage can often be added to your policy, which may cover repairs if your sewer line is damaged due to events like flooding, heavy storms, or plumbing malfunctions. Standard homeowners insurance typically doesn’t cover damages caused by tree roots, clogs, or natural wear and tear. To ensure you have the right coverage, it’s important to contact your insurer and ask about additional sewer line protection options or riders for more comprehensive coverage. Some insurers may offer specific add-ons to protect against unexpected sewer line failures, so it’s worth exploring all available options.
How do you tell if your sewer line needs to be replaced?
Several signs can indicate that your sewer line may need replacing: Frequent Clogs: If your drains clog frequently, even after regular cleaning, it could point to underlying damage or blockage in the sewer line. Foul Odors: Unpleasant smells in or around your home, especially near drains or in your yard, might indicate a sewer line leak or a backup. Water Backups: Continuous toilet or drain backups are strong indicators of a blockage or damage in the sewer line that requires attention. Slow Drains: If your drains are slow to clear, even after plunging, this often signals a deeper issue within the sewer line that could involve cracks or obstructions. In addition to these signs, keep an eye out for moisture or pooling water in your yard, as this can suggest a broken or leaking sewer line. If you notice any of these symptoms, it’s important to contact CPI Service for a thorough sewer line inspection. Our professional team will assess the damage and help determine whether a replacement is necessary.
How long does it take to replace the main sewer line?
The time it takes to replace a main sewer line depends on the method used: Traditional Sewer Line Replacement: This method generally takes 2–3 days as it involves excavation, which requires more time and manual labor to complete. Trenchless Sewer Line Replacement: A quicker option, trenchless replacement usually takes 1–2 days. This method requires minimal digging and disruption, making it a faster solution. At CPI Service, we prioritize both speed and quality, ensuring your sewer line replacement is completed efficiently while maintaining the highest standards of workmanship. We'll work with you to minimize disruption and get your system back to normal as quickly as possible.
How Much Does a New Sewer Line Cost?
The cost of replacing a sewer line can vary based on several factors: Location of the Problem: The distance from your home to the sewer main and the complexity of excavation can influence the total cost. Method Used: Traditional replacement methods tend to be more expensive because they require excavation, while trenchless methods are often more affordable and less disruptive. Type of Pipe Material: The material selected for the new sewer line (e.g., PVC, cast iron, or HDPE) can impact the overall cost due to material prices and installation requirements. On average, sewer line replacement costs between $3,000 and $7,000. However, the final price can vary depending on the specifics of the job. For a more accurate estimate, it’s best to contact a local sewer service provider for a free inspection.
What is the life expectancy of a sewer line?
Sewer lines typically last 30 to 50 years, depending on the material used, such as clay, cast iron, or PVC. However, certain factors can shorten their lifespan, including tree root intrusion, pipe corrosion, and shifting soil or foundation damage. Regular inspections can help identify potential issues early, allowing for timely repairs or maintenance to extend the life of your sewer line and avoid costly replacements.
