When Drains Refuse to Stay Clear: The Truth About Recurring Clogs

 Few things are more frustrating than a drain that keeps clogging, no matter how many times you clean it. You pour in drain cleaner, clean the pipe with a probe, or even call a plumber, only to see the problem return days or weeks later. At that point, it's no longer just an inconvenience; it's a sign of a deeper problem. If your drains refuse to stay clear, it's time to look beyond the surface and understand what's really going on.

It's Not Just "Hair and Soap"

Most homeowners assume clogs are caused by a buildup of hair, grease, soap scum, or food debris. While these are certainly the most common culprits, recurring clogs often indicate something more serious is going on within the plumbing system. You might eliminate the symptom, but leave the root cause intact.

For example, debris buildup inside the pipes may be much larger than can be reached with a plunger or small probe. Over time, grease hardens, mineral deposits from hard water accumulate, and waste begins to form a thick layer that reduces the diameter of the pipes. This means that even a small amount of debris can cause further clogging.

Poor Piping Slope or Design

Another hidden cause of frequent clogs is poor plumbing design. If pipes aren't installed with the correct slope or diameter, water and drains can't flow efficiently. This allows debris to settle in low spots, where it continues to accumulate over time. Older homes, especially those with DIY or outdated plumbing systems, are more likely to have these underlying defects.

Even newly built homes can be subject to poor installation practices, such as sharp pipe angles, improper ventilation, or the use of undersized pipes for high-use drains. If you consistently experience clogs in the same system, it may be a design flaw, not bad luck.

Overreliance on Chemical Drain Cleaners

When clogs become frequent, many homeowners repeatedly resort to chemical drain cleaners. But this creates a new problem: chemical erosion. Over time, these harsh chemicals can corrode the inside of pipes, especially if they're old or made of metal. While they may offer a temporary solution, they often damage the plumbing system and increase the risk of leaks, corrosion, and burst pipes.

What you can do about it

The only way to truly solve recurring drain problems is to identify and address the root cause. This may mean scheduling a professional drain cleaning, a camera inspection, or even redesigning the plumbing system. In some cases, pressure washing, a high-pressure water cleaning method, can completely eliminate buildup inside pipes and restore proper flow.

Preventative maintenance can also be very helpful: avoid pouring grease, food debris, or hygiene products down drains; install hair catchers in showers; and run hot water regularly to keep pipes clean.
