Every homeowner has experienced the frustration of a sink not draining. It can disrupt your daily routine and create an unpleasant mess in your kitchen or bathroom. But what’s even more frustrating is when you try to clear the pipes, but the sink still won’t drain.

It’s essential to understand the possible causes and simple fixes for this common household issue. In this blog post, we’ll provide information on the various reasons why your sink might not be draining despite having clear pipes.

How sink drainage works

In a typical home, the drain system works by allowing water to flow through pipes from sinks, showers, and toilets into a larger main drain that leads to a sewer or septic tank. The plumbing in your home is responsible for ensuring that this drainage system operates smoothly and efficiently.

A clear drain path is essential for proper sink drainage. If there’s a blockage or clog in the pipes, water will not be able to flow freely and will result in a slow or non-existent drain. This can be caused by various factors.

When your pipes are clear of debris, though, there are still a few things that could cause your sink to not drain properly.

Causes of a non-draining sink despite clear pipes

Here are the most common causes of a backed-up sink when your pipes are cleared of clogs.

Incorrect pipe installation or design

In some cases, the issue may not be with the objects or debris in your pipes, but rather with the pipes themselves. If they’re installed at an incorrect angle or have design flaws, it can impede the flow of water. A common sign of incorrect installation is your sink not functioning as it should.

Plumbing installations should always be done by a professional to avoid these issues. An expert will have the tools and knowledge necessary to ensure that your system is properly mapped out for optimal drainage to prevent a leak or flood.

Poorly maintained septic tank

If your home has a septic tank, it’s crucial to ensure that it’s regularly maintained and pumped. Failure to do so can lead to backups in your sink drainage system since the tank is responsible for filtering out solids and allowing only liquid to flow through.

Septic tanks should be pumped every 3 to 5 years, depending on the size and usage of your household. Neglecting this maintenance can result in costly repairs and backups in your sink.

Airlock or plumbing vent issues

Sometimes, it’s not food residue, oil, or hair that gets trapped in your pipes, but air, making it seem like your pipes are seemingly clear. This can prevent water from flowing and can happen if you’ve had recent plumbing work done, or if the pipes haven’t been used for a while. To fix this, try running hot water through the sink or using a plunger to force air out and allow water to flow.

Plumbing vents are designed to release air pressure and allow water to flow freely. If these vents become damaged, it can disrupt the balance of air pressure in your plumbing system, leading to slow or non-existent sink drainage.

When to call for professional plumbing service

While there are several DIY solutions for a non-draining sink (such as using a drain cleaner, plunger, or plumber’s snake), some problems may require the employment of a professional plumber. This includes persistent or recurring slow-draining sinks despite attempts at unclogging and foul odors coming from your drains.

When hiring a plumbing service business, you’ll need to do your research and choose a reputable company. Consider asking for recommendations from friends or family, reading reviews online, and checking for proper licenses and insurance. Vetting your plumber beforehand can save you time, money, and additional hassle in the long run.

It’s also crucial to communicate clearly with the plumber about your specific problem and ask for an estimate before any work is done. This will help ensure that you’re not overcharged for unnecessary services.
