Things You Should Never Put Down Your Drain

Clogged drains are one of the most common plumbing problems homeowners face, yet many of them are completely preventable. Every day, small items and substances go down household drains that slowly build up inside pipes. Over time, this buildup can lead to slow drains, stubborn clogs, foul odors, or even sewage backups.

At The Plumbing Authority, our Knoxville drain and sewer experts help homeowners deal with clogged drains every day. Many of the plumbing emergencies we see start with everyday items that people didn’t realize should never go down the drain.

Whether it’s hair in the shower, grease in the kitchen sink, or “flushable” wipes in the toilet, these materials can stick to the inside of your pipes and create blockages that only professional drain cleaning can remove.

For homeowners in Knoxville, TN, preventing drain clogs is especially important. Many homes in the area have older plumbing systems and sewer lines that can be more vulnerable to buildup and blockages.

In this guide, we’ll cover:

• The most common things you should never put down your drain
• Why these items cause serious plumbing issues
• How to prevent clogged drains in your bathroom and kitchen
• When to call a professional drain cleaning in Knoxville

Common Bathroom Drain Clog Culprits

Bathroom drains deal with a surprising amount of debris every day. From personal care products to hygiene items, many things that seem harmless can cause major drain clogs over time.

Even small items can accumulate and combine with soap residue to create a thick sludge inside pipes.

Avoid Putting These Items Down Bathroom Drains

Cotton balls and cotton swabs

Cotton doesn’t break down in water. Instead, it absorbs moisture, expands, and easily becomes stuck inside pipes.

Paper towels and tissues

Unlike toilet paper, these materials are designed to be durable and won’t dissolve quickly in water, which can lead to stubborn clogs.

“Flushable” wipes

Despite their name, most wipes do not break down like toilet paper. They are one of the leading causes of clogged sewer lines across the country.

Bath bombs

Bath bombs contain oils, salts, and glitter that can build up in pipes and create sticky residue along the pipe walls.

Feminine hygiene products

These products are designed to absorb liquid and expand, which makes them extremely likely to block pipes and drains.

Hair and soap scum

Hair is one of the top causes of clogged shower drains. When combined with soap residue, it forms thick tangles that trap other debris.

What Should Never Go Down Your Kitchen Drain

Kitchen drains are another major source of plumbing clogs. Even homes with garbage disposals can experience problems when certain foods and substances are washed down the sink.

Many homeowners don’t realize that a garbage disposal does not eliminate the risk of drain clogs—it only breaks food into smaller pieces.

Common Kitchen Drain Clog Creators

Coffee grounds

Coffee grounds clump together in pipes and can quickly create thick blockages inside your drain line.

Eggshells

Eggshell membranes can wrap around other debris and form a net that traps food particles.

Vegetable peels and skins

Potato skins, carrot peels, and similar materials are fibrous and can easily get stuck in pipes.

Produce stickers

These tiny stickers don’t dissolve and can catch other debris in your plumbing system.

Oils, grease, and fats

When grease cools, it hardens and sticks to pipe walls. Over time, this buildup narrows the pipe and restricts water flow.

Pasta and rice

Both foods absorb water and expand, which can quickly lead to stubborn kitchen drain clogs.

Butter and dairy products

Like grease, dairy fats can solidify in pipes and contribute to long-term buildup inside your plumbing system.

Simple Tips to Prevent Drain Clogs

The good news is that preventing clogged drains is usually simple with a few smart habits.

1. Use Drain Screens: Install mesh drain covers or hair catchers in bathroom sinks and showers. These inexpensive tools help prevent hair and debris from entering the drain.
2. Dispose of Food Waste Properly: Scrape leftover food into the trash or compost before washing dishes.
3. Avoid Pouring Grease Down the Sink: Instead, pour grease into a disposable container and throw it away once it cools.
4. Flush Drains With Hot Water: Running hot water down your kitchen sink after cooking can help reduce grease buildup.
5. Schedule Preventative Drain Cleaning: Regular professional drain cleaning helps remove hidden buildup deep inside your pipes before it turns into a major clog.

Signs Your Drain May Already Be Clogged

Even with good habits, clogs can still happen. Watch for these warning signs of a blocked drain:

• Slow draining sinks or tubs
• Gurgling noises coming from drains
• Bad smells from your sink or shower
• Frequent clogs that keep returning
• Water backing up in multiple drains

If you notice any of these issues, it may be time for professional drain cleaning in Knoxville.
