What Causes Slow Drains?

Your drains can slow down for several reasons. The most common causes include:

  • Old Pipes: Aging pipes can struggle with corrosion or develop weak spots, leading to slow drainage.
  • Buildup Inside Pipes: Over time, substances like paper products, chemicals, and even corrosion itself can cause a buildup that restricts water flow.
  • Partial Clogs: While you may not see a clog, debris or other materials can accumulate over time, slowing drainage if your pipes haven’t been cleaned recently.
  • Cracked or Collapsed Pipes: A damaged pipe can hinder water flow, as anything going down the drain has more obstacles to pass through before exiting the system.

Identifying and addressing these issues early on can prevent more severe plumbing problems. We’ve written a separate blog post dedicated entirely to the importance of clean drains.

How Bob Oates Repairs Slow Drains

To effectively repair slow drains, it’s essential to first identify the root cause. During a drain inspection, we typically use a specialized camera to examine the condition of your pipes. This remote-controlled camera provides a clear view inside the pipe, helping us detect clogs, cracks, or any tree root invasions. Once we have a precise diagnosis, we can determine the most appropriate repair method for your situation.

Should we find a clog, options to remedy the problem include using cabling or high-pressure water jetting to clear the blockage and ensure smooth water flow. In cases where the pipe is damaged or cracked, we may recommend sewer pipe relining or, if necessary, replacing the pipe.

If tree roots have infiltrated the pipe, not to worry! The team at Bob Oates knows exactly how to tackle roots in pipes. We will discuss your options, which could range from cutting the roots to using trenchless sewer pipe repair to replace the pipe entirely, depending on the severity of the issue. Our goal is to provide you with a solution tailored to the specific problem.

How Spring Can Lead to Sewer Backups
