Sewer Line Repair & Replacement Options
The best option for a sewer line repair depends on the location (access), depth, pipe material and problem such as a clog, crack, collapse, slab leak or root intrusion. We’ll thoroughly inspect the area, diagnose the problem and recommend the best solution.
Manual or Mechanical Snaking/Auger
This method is ideal for blockages caused by grease, debris or tree roots without pipe damage.
Hydro Jetting Sewer Line Repair
This method is best for recurring clogs or issues in multiple areas while fully cleaning the pipe. Hydro jetting is typically more expensive and can lead to pipe damage on older or brittle pipes.
Trenchless Sewer Line Repair and Replacement
Trenchless sewer line replacement allows for the replacement of old or damaged sewer pipes with minimal digging. This is done using techniques like pipe bursting or pipe lining, which only require small access points. It minimizes disruption to your yard or concrete slab while installing a new pipe. However, the existing line must be in good enough condition for this approach.
Trenchless Pipe Lining (cured-in-place pipe (or CIPP) lining)
This is a process where we create a “pipe within a pipe” by installing an epoxy liner inside the existing pipe.
Trenchless Pipe Bursting
Through two access points at the beginning and end, the old pipe is fractured while a new pipe is pulled through the same path.
Trench Replacement or Spot Repair
A trench replacement or spot repair involves digging to down to the problem and either replacing a damaged section or the entire sewer line.
Pipe Reroute
The old sewer line is abandoned, such as an inaccessible one under a concrete slab, and a replacement line is rerouted along a different route.
Causes of Sewer Line Damage in Orange County, CA
From clogged pipes to normal wear and tear, here are a few common causes of sewer line damage:
- Tree Roots – Orange County is loaded with mature, thirsty trees with extensive root systems that are drawn to moisture found in small sewer line cracks that lead to root balls in the sewer lines and even bigger problems.
- Ageing and Corroded Pipes – There are many older Orange County homes with some dating back to the 1800s and combined with the outdated materials that were used plus time, broken, collapsed, punctured or cracks pipes are eventual.
- Poor Construction – Low quality pipes or joints, an incorrect slope or poor support in installations leave many homes vulnerable to cracking, leaks and sewer line failure.
- Seismic Activity – Earthquakes and small tremors from fault lines such as the Yorba Linda fault cause ground movement that can crack or break pipes quickly over time.
- Soil Expansion – While Orange County has some of the best weather in the country there can be periods of heavy rains followed by dry seasons that cause the soil to expand and contract, leading to sewer line bursts and cracks.
- Slab Leaks – Many Orange County homes are built on slab foundations where hidden leaks from cracked or broken sewer lines can lead to many issues.
How to Protect Your Sewer Lines
Regular maintenance on your drains goes a long way when you are trying to avoid problems in your system. Some things you can do to maintain your sewer lines include:
- Pouring boiling hot water down the drain once per week to help break up any errant grease that may have clung on.
- Installing strainers and traps wherever possible to avoid the impact of things like hair or soap scum building up in the drain.
- Clearing out your traps regularly. You can use an auger if necessary to avoid any buildup in the actual drain.
- Checking the air vents on your roof for clogs. If the air vents get clogged, sewer gasses can back up into your system and cause noxious fumes or smells to form.
- Use your sewage system properly — Only dispose of human waste and toilet paper in the sewer lines; any other materials that enter the system can cause blockages.
- Receive sewer line inspections once a year —To confirm that your sewage system is in good working condition, hire a professional to conduct an inspection at least once a year.
