Our Comprehensive Sewer Repair & Replacement Services

Precision Traditional Excavation
While we always prioritize the best method, some situations—like a severe “belly” in the line or a total structural collapse—require traditional excavation. Our team handles these jobs with surgical precision, using top-of-the-line compact excavators to minimize the footprint of the work and ensuring the new line is perfectly pitched for years of trouble-free service.

Sewer Cleanout Installation
Many older homes in San Marcos lack a proper “cleanout”—an access point that allows for easy maintenance and camera inspections. We specialize in installing code-compliant exterior cleanouts, giving you and future plumbers easy access to clear clogs without having to remove a toilet which adds to the job cost or climb onto the roof which can be dangerous, and cause roof damages.

Signs Your Sewer Line Has Reached the Breaking Point
Not sure if you need help?
While clogs happen, structural sewer failure often presents with specific, more serious symptoms. Call Pure Plumbing Company if you notice:
- Multiple Fixtures Backing Up: If using the washing machine causes your shower to gurgle or your toilet to overflow, your main sewer line is likely compromised.
- Lush, Soggy Spots in the Yard: If one area of your lawn is suspiciously green or feels like a sponge even in the dry San Marcos summer, your sewer line could be leaking nutrient-rich wastewater into the soil.
- Indentation in the Pavement: A leaking sewer pipe can wash away the soil beneath your driveway or sidewalk, leading to “sinkholes” or cracked concrete.
- Persistent Rodent or Pest Issues: Rats and sewer flies are attracted to the moisture and debris of a cracked sewer line. If you can’t get rid of pests, the entry point might be underground.

The Impact of North County’s Environment on Your Sewer
San Diego North County is home to aggressive, thirsty trees like Eucalyptus and California Pepper trees. Their roots are naturally drawn to the moisture and nutrients inside your sewer pipes. Over the 10 years we’ve served this area, we’ve seen how even the smallest crack can become a massive root-filled blockage in just a few seasons. Our replacement materials are “root-proof,” designed to keep your home’s waste system secure from the local flora.
