Common Causes of Clogged Drains and How to Prevent Them

Backed up kitchen sink

Clogged drains are a common household nuisance that can lead to unpleasant odors, slow water drainage, and even damage to your home’s plumbing system if issues are left unaddressed. Understanding the root causes of drain clogs in your kitchen, bathroom, and floor drains can help you prevent them and maintain a healthy plumbing system.

The experienced plumbers at Central Heating Cooling Plumbing Electrical in Kalispell have put together a list of the most common causes of clogged drains we see regularly, along with some practical tips on how to keep your drains flowing freely.

Common Causes of Clogged Kitchen Drains

1. Grease and Fat Buildup

Pouring grease, fats, and oils down the kitchen sink is one of the leading causes of clogged drains. As these substances cool, they solidify and adhere to the inside of your pipes, creating stubborn blockages.

Rinsing grease with hot water can make the problem worse by causing the residue to accumulate further down the drain pipe, where it’s harder to clear away without professional drain cleaning.

2. Food Particles

Small food particles and scraps can accumulate over time, especially when not properly disposed of or when the garbage disposal isn’t used correctly. Coffee grounds and tea leaves are some of the worst culprits because they do not break down. Even with a garbage disposal, avoid putting large amounts of food waste down the drain. A compost pile can take the bulk of it.

3. Soap Scum

Have hard water in your home? The combination of soap and hard water can lead to soap scum buildup inside the pipes, narrowing the passageway for water to flow.

How to Prevent Kitchen Drain Clogs

Always Dispose of Grease Properly
Collect grease in a container and throw it in the trash instead of pouring it down the drain.

Use a Drain Strainer
Install a strainer over your sink drain to catch food particles and prevent them from entering the pipes.

Run Cold Water
After using the garbage disposal, run cold water to clear the drain.

Common Causes of Clogged Bathroom Drains

1. Hair Accumulation
Hair is the most common culprit in bathroom drain clogs. It can knot up and combine with soap scum to create dense blockages. Animal fur and dental floss cause the same kind of clog.

2. Soap and Shampoo Residue
Just like in the kitchen, soap and shampoo can leave behind residue that builds up over time, especially with hard water.

3. Foreign Objects
Small items like toothpaste caps, jewelry, or even children’s toys can accidentally fall into the sink or tub drains, causing obstructions.

How to Prevent Bathroom Drain Clogs

Use a Drain Strainer
Place a hair catcher over shower and bathtub drains to prevent hair from going down the drain.

Regular Cleaning
Clean your drains periodically with a natural drain cleaner that uses enzymes to breakdown accumulated debris. Central Heating Cooling Plumbing Electrical recommends Bio-Clean, used about four times a year. Its natural enzymes and bacteria digest the waste in your pipes. Bio-Clean does not harm plastic piping and does not give off fumes the way chemical drain cleaners do.

Be Mindful of What Goes Down the Drain
Ensure small objects are kept away from sink and tub edges to prevent them from accidentally going into the drain.

Common Causes of Clogged Floor Drains

1. Dirt and Debris
Floor drains in basements, garages, or laundry rooms can collect dirt, dust, and debris, leading to clogs.

2. Mineral Buildup
In areas with hard water, minerals can accumulate in floor drains over time, causing blockages.

3. Improper Installation
Incorrectly installed floor drains may not have the proper slope or venting, which can contribute to frequent clogs. If you are experiencing frequent floor drain clogs, have a professional plumber check that everything designed and working correctly.

How to Prevent Floor Drain Clogs

Regular Maintenance
Keep the area around floor drains clean and free of debris.

Install Drain Covers
Use screens or grates to prevent large debris from entering the drain.

Flush the Drain
Periodically pour a bucket of hot water down the floor drain to help clear any buildup. This will also ensure that the trap is filled with water, preventing odors.

Common Causes of Clogged Toilets

Only toilet paper and human waste belong in a toilet, and only as much toilet paper as you need.

  • “Flushable” items. Wipes labeled “flushable,” along with cotton swabs, diapers and feminine hygiene products, do not break down the way toilet paper does. Their bulk or shape can easily cause a blockage.
  • Cat litter. Litter is made to absorb moisture, so it forms clumps that can block a pipe. Bag it and throw it in the trash.
  • Toys. Keep an eye on young children in the bathroom. Small toys can end up in the toilet.

Why We Don’t Recommend Chemical Drain Cleaners

Chemical drain cleaners are only a temporary fix. If a chemical cleaner does not break down the clog, it can cause acid erosion inside the pipe. The chemicals left in the line also create a hazard for the plumber who has to clear it, which can end up costing you more.

When to Call a Professional Plumber

While regular maintenance can prevent most clogs, some issues will require professional attention. If you experience persistent clogs, unpleasant odors, or slow drainage despite your efforts, it’s time to call in the experts at Central Heating Cooling Plumbing Electrical.

If more than one drain is clogged, call a plumber. Sinks, tubs and toilets all drain into the same pipes, so several clogged drains point to a problem in the shared line rather than in one fixture. Offset pipes, tree roots and mineral buildup can also cause clogs that are best repaired by a professional.
