Sewer leaks create a lot of chaos during the course of their existence, regardless of what type of property they occur on. They can cause significant damage to the surrounding structures, increase water bills, and create an awful stench that nobody likes. Because of the nuisances they create, most homeowners prefer to avoid these sewer leaks as much as possible. The key to doing so is in knowing what causes them in the first place. Below, we provide the top five factors that can lead to a sewer leak on your property. 

Causes for Sewer Leaks

Digging in the Wrong Place

Whether you’re trying to plant a tree, install a pool, or work on some other home improvement projects, any digging you do must be considered carefully. It is important to ensure you know where the sewer lines are and avoid digging at them at all costs. Otherwise, you will end up in dire and urgent need of plumbing repairs in Dallas

To avoid this issue, contact a local plumber to help determine where those sewer lines are located. Additionally, try to leave the digging to the pros who will consider those sewer lines as part of their job. This may seem unnecessary, but it will save you time and money on any potential sewer repairs down the line. 

Tree Roots

Got any tall and fairly old trees on the property? Chances are that the tree roots are long enough to cut through the sewer lines, leading to a leak. Having those tree roots checked out is essential to ensure that you won’t be facing the hassle of dealing with a sewer leak in the future. A simple, annual plumbing maintenance check will go a long way to preventing this type of stress and expense. 

Natural Causes

Texas is a state that gets hit with hurricanes and other severe weather storms. Heavy rain can also cause sewer leaks. Unfortunately, there are few to zero things that can be done about preventing natural causes from taking their course. However, if you’re just recovering from a hurricane or other storm, it wouldn’t hurt to have a plumbing repair tech in Dallas come to check out your sewer lines. Even if there is a leak, they can stop it quickly and prevent much of the damage that occurs when it is left without a resolution. 


Rust is a common concern for homes that were built before the1970s because the piping used during that period was made with cast iron. As those cast iron pipes end their lifespan, they will develop rust and corrosion. That corrosion will lead to an inevitable gap and leak anywhere in the pipes. If your home was built before the 1970s, consider contacting a plumbing repair tech in Dallas to inspect the quality of your pipes. Below are some common signs that your home’s plumbing may need replacement due to rust or corrosion:     

  • Your home was built before the 1970s
  • Discolored water
  • The water smells like iron or copper
  • Water tastes like iron
  • Poor water pressure
  • Weird sounds in the plumbing
  • Inconsistent water temperatures

If you notice any of these signs in your home, it is important to contact a professional immediately. Lead poisoning is a very real concern that carries with it many adverse health implications. Do not put off this discussion with your plumber. 

Excessive Clogs

If your sewer line develops a large enough clog, it can burst and result in a leak. This plumbing issue will result in a pipe replacement, which can be very expensive. Pay attention to the following signs of sewer clogs in order to get timely help for your plumbing clogs: 

  • Slow drainage in fixtures and faucets
  • Toilet gurgling 
  • Frequent toilet backups
  • Foul smells coming from drains 
  • Sewer line cleanout is backed up

If you notice any of these issues, contact a plumber as soon as possible to save yourself from the nightmare of a sewer leak.
