When it comes to maintaining a functional home in Portland, OR, ensuring the integrity of your sewer line is crucial. Sunset Heating & Cooling offers comprehensive sewer line repair and sewer line replacement services to address any issues promptly and effectively. If you suspect damage to your home’s sewer line, the first step is to request a professional inspection. Our technicians use advanced digital cameras to check for clogs, leaks, and cracks. Owners of older homes should consider having their main sewer line inspected at least once every 10 years.

Traditional Sewer Line Repair

For severe damage, such as tree root penetration or significant breaks, traditional sewer line repair may be necessary. This method involves excavating a trench around the damaged sewer line to access and repair it. Here's how the process typically works:

  • Survey and Marking: The area is surveyed, and underground utilities are marked. Traffic control devices may be put in place if needed.
  • Excavation: Technicians excavate trenches along the sewer line path using backhoes or excavators. Walls are shored up for safety when digging deeper than 4 feet.
  • Removal and Replacement: The damaged pipe sections are disconnected and lifted out. New pipe sections are laid and sloped for proper drainage, then fused or sealed together.
  • Reconnection: The lateral pipes from your home are reconnected to the new sewer main using flexible couplings. Maintenance holes are installed if required.
  • Backfilling: The trenches are backfilled with gravel and compacted. The surface is patched or repaved to match the surroundings.
  • Final Inspection: A final video inspection checks for proper installation and drainage flow before activating the new system.

Trenchless Sewer Line Repair

Not all sewer line damage requires extensive digging. Trenchless sewer repair is a cost-effective and less disruptive alternative, ideal for urban areas. This method uses special machinery to repair the pipe with minimal ground disturbance. Two common trenchless repair techniques are pipe bursting and pipe lining.

Pipe Bursting Repair

Pipe bursting involves replacing the old pipe by fracturing it and pulling a new pipe into place. The process typically includes:

  • Entry and Exit Pits: Pits are dug at the entry and exit points along the pipe path.
  • Bursting Equipment Setup: The bursting equipment is lowered into the entry pit, and the new HDPE pipe is attached behind the bursting head.
  • Pipe Bursting: The bursting head is launched into the old pipe, breaking it apart and pulling the new pipe behind it.
  • Connection and Restoration: The new pipe is connected to the plumbing system, the pits are filled, and the surface is restored.

Pipe Lining Repair

For minor cracks and leaks, pipe lining repairs involve installing a new liner inside the old pipe, extending its life by 50 years or more. The steps include:

  • Inspection and Cleaning: The old pipe is inspected and cleaned typically using a hydro-jetting method.
  • Liner Insertion: A liner tube saturated with resin is inserted into the old pipe. An inflatable bladder holds the liner against the inner walls.
  • Curing: Hot water or steam cures and hardens the resin into a smooth, jointless pipe liner.
  • Reconnection: Robotic cutting devices reopen the lateral connection points, and the ends of the liner are sealed.

    Typical Sewer Line Problems That Require Repairs in Portland, OR

    Your home’s sewer line is essential for carrying wastewater away from your property. Unfortunately, sewer lines are prone to issues that can cause significant disruptions, such as flooding, pipe deterioration, and corrosion. Understanding common sewer line problems and their solutions can help you maintain your system efficiently. Sunset Heating & Cooling in Portland, OR, offers expert services to address these issues effectively. Some of the most common sewer repairs our plumbers have to deal with on a daily basis are the following:

    Cracked Sewer Lines

    Cracks in sewer lines can result from aging, ground shifting, tree roots, or external pressure. Signs of a cracked sewer line include lush patches of grass in your yard, indicating nutrient-rich wastewater leakage. Cracked sewer lines can lead to significant blockages if left untreated. Repairs can involve traditional excavation or trenchless methods like pipelining, which are less invasive and more cost-effective.

    Collapsed Sewer Lines

    These usually present immediate and severe problems, including multiple drain backups, sinkholes, foul odors, and sewage leaks. Causes include aging pipes, ground shifting, excessive pressure, and tree root intrusion. Repairing a collapsed sewer line typically involves excavation to replace the damaged section. Alternatively, trenchless methods like pipe bursting can be used, depending on the situation.

    Tree Roots Growing Through the Sewer Line

    Tree roots naturally seek moisture and can penetrate sewer lines through small cracks, causing blockages and even pipe collapse over time. Hydro-jetting is an effective method to clear roots and debris, and chemical treatments can prevent future root growth. Severe cases may require excavation and pipe replacement.

    Offset Sewer Line Pipes

    Offset sewer pipes occur when sections of the sewer line become misaligned, often due to ground shifting. This misalignment disrupts wastewater flow, causing blockages, slow drainage, and potential leaks. Solutions include pipelining, where a resin-coated liner is inserted and inflated to create a new, seamless pipe within the old one, or traditional excavation to realign or replace the offset sections.

    If you are experiencing any of these issues or any other sewer line problem, it’s crucial to address them promptly to prevent further damage.
