What Are the Experiences of Bay Area Clients with Our Drain and 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.

Signs You Need Professional Drain Cleaning
In San Francisco Bay Area homes, plumbing issues often stem from aging infrastructure, root intrusion, or accumulated debris. If left unchecked, early signs of clogged or slow drains can escalate into costly repairs and potential property damage. Pay attention to the following indicators, and if you notice any of them, it is time to contact a professional drain cleaning service.
- Slow Draining Sinks & Toilets: Slow drainage often signals deep blockages in the pipes, requiring immediate attention. For example, if your kitchen sink takes several minutes to drain after washing dishes, or your toilet is sluggish when flushed, these could be signs of a blockage deep within the plumbing.
- Foul Odors From Drains: Unpleasant smells typically indicate trapped waste or stagnant water in your plumbing system. For instance, if you notice a strong, musty odor coming from your bathroom sink or shower drain, it may be a sign that waste has built up in your pipes and needs to be cleared.
- Frequent Clogs & Backups: Recurring blockages suggest that there’s an unresolved issue within the drain lines. If your bathtub frequently gets clogged after just one use or you experience repeated backups in your kitchen sink, this could point to a deeper plumbing issue requiring professional attention.
- Gurgling Sounds in Pipes: Bubbling or gurgling noises are usually caused by air pockets due to partial blockages. For example, if you hear strange gurgling sounds from your toilet or sink when you flush or drain water, this may be caused by air being trapped behind a partial clog in the pipes.
- Standing Water in Bathtubs or Showers: If water is not draining properly, it is a clear sign of a serious clog. For instance, if your shower takes forever to drain, or you’re left with standing water after using the bathtub, this indicates that there is a significant blockage that needs to be addressed immediately.
Ignoring these early warning signs can lead to more significant plumbing problems. Contact CPI Service today to keep your plumbing running smoothly and avoid expensive repairs.

Drain and Sewer FAQs for San Francisco Residents
What Is the Average Cost of Sewer Drain Cleaning in San Francisco?
The average cost of sewer drain cleaning in the San Francisco Bay Area ranges from $170 to $1,000, depending on the severity of the clog, the method used, and the location of the issue. Factors like whether it requires standard cleaning, hydro jetting, or a more complex intervention can influence the final cost.
Who is responsible for drains and sewers?
In most cases, homeowners are responsible for the maintenance and repair of the drain lines that connect their property to the main sewer line. This includes issues within the property’s plumbing system. However, the local municipality typically owns and maintains the main sewer lines that run beneath public streets. It is important to know where your responsibility ends and the public system begins to avoid unexpected costs.
What Is the Difference Between a Drain and a Sewer?
A drain refers to the pipes within your home or business that carry wastewater from sinks, showers, toilets, and appliances to the main sewer line. A sewer, on the other hand, is the larger network of pipes that transports wastewater from multiple properties to a treatment facility or septic system. Essentially, drains are part of the plumbing system inside your property, while sewers handle waste from multiple buildings in a community.
Do all house drains go to the sewer in San Francisco?
In San Francisco, most residential properties are connected to the city's municipal sewer system. The drains inside your home carry wastewater to the main sewer line, which then transports it to the city's treatment facilities. However, some properties, particularly those in older or more rural areas, may still rely on septic systems. It is important to check your property’s connection to ensure proper maintenance and avoid potential plumbing issues.
