How to Prevent Sewer Line Issues in Older Homes

Owning an older home brings with it a unique blend of charm and character. These homes often feature beautiful craftsmanship and historic details, but they can also hide plumbing systems that are well past their prime. One of the most common and potentially costly plumbing issues in older properties is a damaged or deteriorating sewer line.

Fortunately, with the right maintenance practices and expert support, you can prevent many of these problems before they spiral out of control. Parson Plumbing and Drains helps homeowners safeguard their homes from sewer issues in Columbus and throughout Central Ohio. Here are our tips to maintain and protect your aging home’s plumbing for years to come.

Why Are Older Homes at Higher Risk?

Many homes built prior to the 1970s used materials for sewer lines that are no longer considered reliable by today’s standards. Clay pipes, for instance, are brittle and prone to cracking under pressure. Cast iron pipes, although sturdy when new, tend to corrode from the inside out, leading to constricted flow and eventual collapse. Even more problematic is Orangeburg pipe, a fiber-based material used from the 1940s to the 1970s, which softens and deforms with age, making it highly susceptible to breakage.

These aging materials are only part of the problem. Decades of shifting soil, freeze-thaw cycles, and natural root growth can all contribute to the degradation of your sewer system. Additionally, the increased use of modern appliances and larger water volumes in today’s homes can place extra strain on older pipes that were never designed for this level of usage. All of these factors combine to make older homes more vulnerable to sewer issues and more in need of preventive attention.

Know the Warning Signs of Sewer Trouble

One of the best ways to avoid a full-scale sewer emergency is to learn the early warning signs of trouble. Pay attention to symptoms like slow drains in sinks, tubs, or showers that don’t respond to normal cleaning methods. You might also notice frequent toilet backups or strange gurgling noises coming from your pipes. If you detect a persistent sewage odor indoors or outdoors, or see wet patches and lush green spots in your yard even in dry weather, these are red flags that your sewer line could be leaking or clogged.

In some cases, you may even notice multiple plumbing fixtures backing up at once, such as the toilet, shower, and washing machine, which typically indicates a blockage deeper in the main sewer line.

These signs should never be ignored, especially in older homes where deterioration is more likely to be the culprit.

How to Prevent Sewer Line Problems

Preventing sewer line problems starts with regular attention and smart habits. Begin by scheduling a professional plumbing inspection every few years, and even more frequently if your home is more than 40 or 50 years old. Modern camera inspection technology allows plumbers to check the condition of your pipes without excavation, giving you peace of mind and the ability to address small issues before they turn into expensive repairs.

Be cautious about what goes down your drains. Only flush toilet paper—never wipes, feminine products, or paper towels. Avoid pouring grease, fats, or food particles into the sink, as these can solidify in the sewer line and cause blockages. Installing a backwater valve can also protect your home from sewage backups during periods of heavy rain, especially in neighborhoods with aging municipal systems.

Roots from nearby trees and shrubs are a common culprit in sewer line problems, especially in older homes with clay or Orangeburg pipes. These roots naturally seek out moisture and can infiltrate even the smallest cracks in your line. If you have large trees near your sewer main, consider a root barrier or schedule annual hydro-jetting to keep the line clear. And if your pipes are made of outdated materials, replacing them with durable modern piping may be the most cost-effective long-term solution.
