Why Your Drains Keep Clogging And How To Prevent It

A slow drain once in a while is normal. But if your sinks, tubs, or showers keep clogging, it’s usually a sign of a deeper plumbing issue.

Across the Greater Chicagoland area — from Naperville and Wheaton to Aurora and Schaumburg — recurring drain clogs are one of the most common plumbing complaints homeowners face. And in older Illinois homes, the problem often goes beyond simple buildup.

Here’s what causes frequent drain clogs, what homeowners can safely do, and when to call Precision Today for professional drain cleaning.

What Homeowners Need to Know About Recurring Drain Clogs

Your plumbing system is designed to move wastewater efficiently away from your home. When drains clog repeatedly, it usually means:

• Buildup is forming deep inside the pipe

• There’s a blockage in the main sewer line

• Tree roots have entered underground pipes

• The pipe has collapsed or shifted

Ignoring frequent clogs can lead to backups, pipe damage, or even basement flooding.

Common Causes of Drain Clogs in Chicagoland Homes

Let’s break down the most common reasons drains keep clogging.

1. Grease Buildup in Kitchen Drains

Even if you don’t pour grease directly down the sink, cooking oils and fats can accumulate over time.

Here’s how it happens:

• Grease enters as liquid

• It cools and solidifies inside pipes

• Food particles stick to it

• Buildup thickens gradually

In homes with older cast iron pipes, grease adheres more easily to rough interior surfaces.

2. Hair and Soap Scum in Bathroom Drains

Bathroom sink and shower clogs are typically caused by:

• Hair

• Soap residue

• Toothpaste buildup

• Personal care products

Hard water — common in Illinois — worsens the issue by creating mineral deposits that narrow pipes.

3. Tree Root Intrusion

Tree-lined streets are beautiful, but roots naturally seek moisture. Older sewer lines made of clay or cast iron are especially vulnerable.

Signs of root intrusion include:

• Multiple drains clogging at once

• Gurgling toilets

• Sewage smells

• Basement floor drain backups

This is especially common in established neighborhoods throughout Downers Grove, Elgin, and Bolingbrook.

4. Collapsed or Shifted Sewer Lines

Illinois soil expands and contracts during freeze-thaw cycles. Over time, this movement can:

• Shift pipe joints

• Crack sewer lines

• Cause sagging sections (“bellies”)

• Restrict water flow

When wastewater collects in a sagging section, repeated clogs occur.

5. Flushing Non-Flushable Items

Many products labeled “flushable” don’t break down properly.

Common offenders include:

• Wipes

• Paper towels

• Feminine hygiene products

• Cotton swabs

These materials often accumulate in the main line.

6. Improper Drain Slope or Installation Issues

In some homes, especially older properties or DIY renovations, pipes may not have the correct slope.

Without proper gravity flow:

• Water drains slowly

• Debris settles

• Blockages form

Professional inspection can determine whether installation issues are contributing to clogs.

How to Know If It’s a Main Sewer Line Problem

If only one fixture is clogged, the issue is likely localized.

But if you notice:

• Multiple slow drains

• Backups in lower-level fixtures

• Toilet gurgling when sinks drain

• Water backing up in basement drains

…it may indicate a main sewer line blockage.

This requires immediate professional attention.

What Homeowners Can Safely Try

Before calling for service, you can try these safe steps:

Drain Prevention Checklist

• Use drain strainers in sinks and showers

• Avoid pouring grease down the drain

• Run hot water after using the kitchen sink

• Use baking soda and vinegar (occasionally)

• Never use chemical drain cleaners repeatedly

Chemical cleaners can damage pipes, especially older ones.

If clogs return quickly, it’s time for professional service.

Why Professional Drain Cleaning Is More Effective

Store-bought drain snakes and chemicals only remove surface-level clogs.

Professional drain cleaning offers deeper solutions.

Mechanical Snaking

A drain auger can:

• Break up localized clogs

• Clear hair buildup

• Remove minor obstructions

However, it may not fully clear heavy grease or roots.

Hydro Jetting

Hydro jetting uses high-pressure water to:

• Blast away grease buildup

• Remove scale

• Clear tree roots

• Restore pipe diameter

This method thoroughly cleans pipes instead of just punching a hole through the blockage.

Hydro jetting is often ideal for older Chicagoland homes with recurring clogs.

Why Recurring Clogs Shouldn’t Be Ignored

Repeated blockages increase pressure inside pipes.

Over time, this can cause:

• Pipe cracks

• Joint separation

• Sewage backups

• Costly repairs

Addressing the root cause early saves money and stress.

Preventing Future Drain Problems

Prevention is always more affordable than emergency plumbing repairs.

Long-Term Drain Maintenance Tips

• Schedule annual drain inspections

• Consider sewer camera inspections for older homes

• Install backflow prevention devices

• Upgrade aging sewer lines when necessary

• Add a water softener to reduce mineral buildup

Routine maintenance keeps your plumbing system flowing smoothly.

Frequently Asked Questions About Drain Clogs

Why do my drains clog again shortly after I clear them?

Surface-level clearing often leaves buildup behind. Professional cleaning removes deeper obstructions.

Is hydro jetting safe for older pipes?

Yes, when performed by trained professionals after inspection.

Can tree roots be permanently removed?

Hydro jetting clears roots, but severely damaged pipes may require repair or replacement.

How often should drains be professionally cleaned?

Many homes benefit from professional cleaning every 1–2 years.

A Real-World Example

Last summer, a homeowner in Wheaton contacted Precision Today after experiencing repeated kitchen sink clogs.

Although store-bought cleaners temporarily improved drainage, the problem kept returning.

A camera inspection revealed heavy grease buildup deep in the line. After professional hydro jetting, the pipes were fully restored — eliminating the recurring issue.
