Bringing commercial-grade expertise to residential shared sewer lines, backed by our 1-year warranty and 5-star service guarantee.
Many older homes in the Portland metro area were built with shared sewer lines. A shared system means two or more properties route their wastewater through a single pipe before connecting to the main city sewer infrastructure. While these configurations were common in historical neighborhoods constructed throughout the early to mid-1900s, shared setups frequently lead to neighborly disputes, complex maintenance issues, and non-compliance with current municipal city codes.
When an issue occurs deep within a shared pipe, identifying the exact location of the blockage or break is difficult without proper diagnostic tools. Plumbers must determine whose property the damage sits on, which side of the line is causing the backup, and how to fix the problem without disrupting wastewater flow for multiple households. Lovett Plumbing specializes in comprehensive party sewer line repair and complete shared sewer line separation, removing the guesswork from these complicated property scenarios.
Our team approaches your home with the exact same rigor we apply to large-scale commercial projects. We utilize specialized equipment to map out your existing party sewer line, ensuring that your residential property receives an independent, reliable, and fully compliant sewer connection.
Depending on the specific layout of your property and the condition of the existing pipes, Lovett Plumbing provides several targeted solutions to resolve shared wastewater issues.
The most definitive solution to a shared line problem is complete separation. Our technicians cap the connection to the neighboring property and route a brand-new, independent sewer line directly from your home to the public city main. Building an independent line guarantees total control over your plumbing system and ensures full compliance with local real estate regulations.
If separation is not immediately required by the municipality or is financially unfeasible in the short term, our team can execute precise party sewer line repair. We utilize commercial-grade diagnostic equipment to locate the exact point of failure along the shared section of pipe. Once identified, we implement structural repairs to restore proper flow, coordinating the work carefully to minimize wastewater disruption for all connected properties.
Whenever the soil composition and property layout allow, we highly recommend trenchless pipe repair methods for party line projects. Trenchless techniques, such as pipe bursting, allow us to install an independent line or repair a shared line with minimal excavation. Foregoing a massive trench preserves your landscaping, hardscaping, and driveways while accelerating the overall project timeline.
Because party lines accept wastewater from multiple homes, backups happen rapidly and aggressively. Lovett Plumbing provides 24/7 emergency response for severe blockages. When a neighbor's tree roots or flushed debris cause raw sewage to enter your home, our technicians arrive quickly with heavy-duty hydro jetting equipment to clear the immediate hazard before assessing long-term separation needs.
Addressing a shared sewer connection provides immediate relief from wastewater backups and delivers significant long-term financial benefits for your property.
Regulatory Compliance & Easier Home Sales: In many local jurisdictions throughout the Pacific Northwest, properties with party sewers must separate their lines before the house can be sold. Municipalities also frequently mandate separation when homeowners apply for major remodeling permits. We ensure your plumbing infrastructure is completely up to code, preventing delays during real estate transactions.
Eliminate Shared Liability: If a neighbor flushes inappropriate items down their drains or has aggressive tree roots invading their side of the pipe, the shared main can easily back up into your basements or ground-floor bathrooms. Separation completely eliminates this cross-property risk, giving you total, independent control over your plumbing system.
Increased Property Value: An independent, modernized sewer line is a massive selling point for prospective buyers. Future owners actively seek properties that avoid the legal headaches, shared maintenance costs, and physical damage risks associated with an outdated party connection.
Guaranteed Peace of Mind: We back our party sewer line repair and separation work with a comprehensive 1-year warranty. Combined with our commitment to delivering 5-star service 100% of the time, you can trust that your new installation is built for long-term durability.
When converting a property from a shared line to an independent system, the quality of the new infrastructure dictates the longevity of the repair. Lovett Plumbing brings high-level technical proficiency to residential properties by installing durable, commercial-grade piping materials for our new sewer installations.
These modern piping materials resist ground shifting, repel invasive tree roots, and handle high-volume wastewater flow much more effectively than the original clay or cast-iron pipes found in older Portland neighborhoods. By utilizing advanced materials, we ensure your newly separated line functions reliably for decades.
Navigating a shared sewer separation requires strict professional accountability and clear communication. We handle the technical complexities so you never have to guess about the status of your project.
The separation process begins by deploying high-resolution video inspection cameras directly into your plumbing system. Our technicians accurately map the existing party sewer line, pinpoint the exact connection point where the neighboring property ties in, and assess the structural condition of the pipe leading to the city main.
Navigating city codes for shared sewers requires specific municipal knowledge. Our team handles the local regulatory requirements for you. We secure the necessary excavation or trenchless permits, coordinate with utility locating services, and map out the most efficient, non-disruptive routing path for your new independent line.
Depending on your property's topography, landscaping features, and the depth of the city main, we utilize either minimally invasive trenchless technology or traditional excavation. Our crews safely install the new independent sewer line, maintaining a clean and secure work environment throughout the installation phase.
Once the new pipe is in place, we safely disconnect and securely cap off your old tie-in to the neighbor's party line. We then connect your new pipe directly to the city main. Before leaving the site, our technicians perform a rigorous final flow test and coordinate the necessary municipal inspections to verify full compliance.

We had an emergency last night at our community. I called Lovett and got an actual person on the phone right away. The plumber Sarah showed up in short order with a fantastic can do attitude, ready to get to work right away. The drain proved to be a significant challenge to clear but Sarah was bound and determined to clear it for our residents. She was there for hours and would not quit or give up! She even had to leave to grab more equipment and came back working late into the night. She was very thorough and unwavering in her commitment to get the job done. Lovett hires only the best of the best! I would recommend this company to anyone who wants the job done right and right away! I Lovett!!!

Dan from Gladstone was prompt, courteous, and thorough in diagnosing our plumbing issues and finding a good solution. He was experienced and knowledgeable and offered good advice for maintaining our bath/shower plumbing going forward.

Brandon was a lifesaver. In just two hours, he figured out what our rental maintenance team and another contractor couldn't—the leak was coming from upstairs. He didn't stop there either. He cleaned up the mess left behind, helped reduce the active leaking, and made sure everything was handled as well as possible on our end.

Right before Christmas, we discovered a leaking water main when our water bill was more than 3x the same period last year. On short notice, Lovett was able to get Doug out to make an initial assessment, then Brian got me an estimate without delay. Foreman Steven showed up Monday morning and was able to head off potential delays by thinking creatively. He set things up nicely so that we had water running again by late Tuesday morning!

Lovett was dispatched to fix a leaky bathtub faucet in our rental home, and the service I received was top notch! Jill reached out to me quickly and was able to schedule us for the next day. Our plumber Cameron was friendly, gave us heads-up when he would be here so I could secure our furry friends, and was able to resolve the issue no problem! I definitely would recommend Lovett for your plumbing needs.

I had a kitchen sink issue. Lovett came out, and Greg was my tech. Very smart and informative. He was efficient and clean. He answered questions. And my sink was cleared up in an hour. I was so thankful for the service and reasonable price. I will use them again for any bigger projects that might come my way. I recommend this Company fully.

I hadn't lived in my new place for ten days when a pipe broke. Dan came first thing the next morning, cut a 5x10 hole in the wall and capped off the pipe - problem solved! He also took the time to turn down the heat on my hot water heater, and explain the plumbing system to me. I wish I could give him another star.

I had a major issue with my well system and was completely without water. After calling many companies who all said they couldn't help, I reached Ken Williams at Lovett. Ken was immediately attentive, kind, and incredibly knowledgeable. He helped me troubleshoot the problem and quickly got their equipment scheduled and out here to get the repair underway. His professionalism and genuine care made all the difference.

Tyler came out today to inspect/replace my garbage disposal and it was such a great experience! He made the interaction very personable. He also explained different things about the process along the way and I really appreciated that along with how clean he was. He wore shoe covers and completely cleaned up the underneath of my sink as well as the yuckies in the bottom of my sink. Overall, I highly recommend!!
