How to Repair Cracked Sewer Pipe

Broken sewer pipes are not only a nuisance but can also be hazardous to your health. Raw sewage backups and flooding can cause serious damage to your home or business. Therefore, it is crucial to know how to detect and repair a cracked sewer pipe promptly. This article provides a complete guide on how to repair a cracked sewer pipe, factors that affect the repair cost, and when to replace a sewer pipe.

What are the Signs of a Cracked Sewer Pipe?

Detecting a cracked sewer pipe early is crucial as it helps prevent further damage to the sewer system and your property. Some of the signs that may indicate a broken sewer pipe include:

Slow Drains

If you notice that your sink, shower, or bathtub drain slower than usual, it could be a sign of a broken sewer pipe. A cracked sewer pipe can cause blocked water flow, leading to the backing up of water in your plumbing fixtures.

Unpleasant Odors

A foul smell emanating from your plumbing system is a red flag for a broken sewer pipe. Cracked pipes will expose the sewer to the air, and the stench can spread all over your property. This smell can attract unwanted pests, creating a hazardous environment for you and your family.

Water Pooling in Yard

If your yard has standing water despite recent dry weather, it could be a sign of a broken sewer pipe. Cracked pipes can leak wastewater into the soil, which will pool in the yard, creating a breeding ground for insects and diseases.

How to Repair a Cracked Sewer Pipe?

Once a broken sewer pipe is detected, it is crucial to have it repaired promptly. Professional plumbers use various methods to repair cracked sewer pipes, including:

Trenchless Sewer Repair

Trenchless sewer repair is an advanced method of repairing a broken sewer pipe without damaging your landscape. This method involves inserting a flexible tube into the damaged pipe, which will expand and fill in the area, covering the crack and creating a new pipe within the damaged pipe.

Sewer Pipe Lining

Sewer pipe lining is another trenchless sewer repair method that involves inserting a flexible tube coated with epoxy resin into the damaged pipe. The material will coat the cracked area, creating a new protective barrier that strengthens the pipe.

Pipe Bursting

Pipe bursting is a trenchless sewer repair method that involves replacing an existing pipe with a new one. This repair method is best for heavily damaged pipes, and it is less disruptive to your landscape.

What are the Factors that Affect the Repair Cost?

Repairing a cracked sewer pipe is not a one-size-fits-all solution, and the repair cost will vary depending on several factors, including:

Type of Pipe

The type of pipe in your sewer system determines the repair technique and the cost of the repair. PVC pipes are cheaper to repair than cast iron or concrete pipes.

Extent of Damage

The extent of damage to the sewer pipe will determine the complexity and cost of the repair. A minor crack will cost less to repair than a heavily damaged pipe.

Location of the Pipe

The location of the broken sewer pipe will also affect the repair cost. Pipes that are easy to access will cost less to repair than those that require extensive excavation.

Can You Repair a Cracked Sewer Pipe on Your Own?

DIY sewer pipe repair is not recommended as it is hazardous and may result in further damage to your sewer system. However, for minor cracks, some DIY methods can help alleviate the problem temporarily. Some of the tools required for a DIY repair include:

DIY Methods for Minor Cracks

To fix minor cracks, you can use a pipe sealant or epoxy resin. These sealants can cover the crack, preventing water leakage temporarily.

Tools Required for Repair

To fix a broken sewer pipe, you will need specific tools, including a sewer camera, a pressure gauge, and pipe-cutting tools. These tools are expensive, and buying them for a one-time repair can be costly.

Possible Risks of DIY Repair

DIY sewer pipe repair poses many risks, including personal injury, damage to property, and contamination of the soil and groundwater. Therefore, it is crucial to hire a professional plumber to handle any sewer repair.

When to Replace a Cracked Sewer Pipe?

Sewer pipes have a lifespan of up to 60 years, depending on the material used to construct them. However, factors such as tree roots invasion, corrosion, and age can cause the pipes to break or deteriorate. If you notice any of the following signs, it may be time to replace your sewer pipe:

Age of the Pipe

If your sewer pipe is over 60 years old, it’s best to replace it, as it has already exceeded its lifespan.

Number of Repairs Needed

If you have had several repairs on your sewer line recently, it may be time to replace the entire line. Frequent repairs are an indication of deeper underlying problems.

Other Problems with the Sewer System

If you have other problems with your sewer system such as blockages, backups or sewage flooding, it may be time to consider a new sewer line. These problems can cause irreparable damage to your property, resulting in costly repairs. Overall, repairing a cracked sewer pipe can be a complex process, and it’s always a good idea to consult with a professional plumber to assess the situation and determine the best course of action. Regardless of the repair method or cost, regular maintenance of the sewer system can help prevent future problems and prolong the life of the pipes.
