What Not to Put Down the Drain Even When People Say You Can

Blocked drains are one of the most common plumbing problems in Australian homes. The frustrating part is many of them are completely preventable.

Most drain issues do not happen overnight. They build slowly over time from everyday habits people think are harmless.

You have probably heard phrases like:

“It is only a little bit.”
“The hot water will wash it away.”
“The label says flushable.”

Unfortunately, many of these common beliefs lead directly to blocked pipes, slow drains, unpleasant smells and expensive plumbing repairs.

Here is what should never go down your drains, even when people say it is safe.

Cooking Oil and Grease

Grease is one of the biggest causes of kitchen drain blockages.

When hot oil is poured down the sink it may look harmless at first. Once it cools inside the pipes it begins to harden and stick to pipe walls. Over time it traps food scraps and debris until the drain narrows or completely blocks.

This includes:

• Cooking oil
• Bacon grease
• Butter
• Fat from roasts
• Gravy
• Sauces
• Salad dressing

Better for your plumbing

Allow grease and oil to cool first. Pour it into a container or jar and place it in the bin once solidified.

It also helps to wipe greasy pans with paper towel before washing them.

Coffee Grounds

Coffee grounds are small though they create major problems inside drains.

They clump together easily, especially when combined with grease or soap residue. Over time this creates a thick sludge inside pipes.

A safer choice

Place used coffee grounds in the bin or compost instead of rinsing them down the sink.

“Flushable” Wipes

One of the biggest plumbing myths is that flushable wipes are safe for toilets.

Unlike toilet paper, wipes do not break down properly in water. They stay intact for long periods and easily catch inside pipes and sewer systems.

This includes:

• Baby wipes
• Toilet wipes
• Makeup wipes
• Cleaning wipes
• Disinfectant wipes

Protect your pipes by

Keeping all wipes out of the toilet completely, even those labelled flushable.

Paper Towel and Tissues

Paper towel and tissues are designed to stay strong when wet. That is exactly why they should not be flushed.

They take much longer to break down than toilet paper and can quickly contribute to blocked drains.

The better way

Only flush toilet paper that is designed for sewer systems.

Everything else belongs in the bin.

Rice, Pasta and Flour

Rice and pasta continue expanding after coming into contact with water.

Flour creates a sticky paste that clings to pipe walls and traps other debris flowing through the drain.

A plumbing friendly habit

Scrape food scraps into the bin before rinsing dishes or cookware.

Eggshells

Many people still believe eggshells help sharpen garbage disposal blades.

The reality is eggshell membranes can wrap around moving parts while shell fragments combine with grease and food waste inside pipes.

A smarter alternative

Place eggshells in compost or household waste instead.

Hair

Hair is one of the leading causes of bathroom drain blockages.

It tangles easily and binds with soap scum inside pipes, creating thick clumps that slow water flow.

Keep your drains clear by

Using drain guards in showers and bathroom sinks and cleaning them regularly.

Dental Floss

Dental floss does not dissolve in water.

It can wrap around debris inside pipes and slowly contribute to larger blockages over time.

Better habits matter

Dispose of dental floss in the bin instead of rinsing or flushing it away.

Medication

Flushing medication down the toilet or sink can affect waterways and the environment.

Wastewater systems are not designed to fully remove pharmaceutical chemicals.

An easier solution

Take unused or expired medication to your local pharmacy for safe disposal.

Paint and Chemicals

Paint, solvents and harsh chemicals should never enter household drains.

These substances can damage plumbing, create hazardous fumes and contaminate water systems.

A safer option

Use approved disposal facilities for chemicals, paints and hazardous waste products.

Fruit Stickers

Those small stickers found on fruit can create surprisingly large plumbing problems.

They do not dissolve in water and can become trapped inside pipes or water treatment equipment.

Simple prevention helps

Remove fruit stickers before washing produce and place them in the bin.

Cat Litter

Even products labelled flushable can cause serious drain blockages.

Cat litter absorbs water and expands quickly inside plumbing systems.

A better approach

Bag used litter securely and place it in the rubbish bin.

Bones and Food Scraps

Large food scraps do not disappear once rinsed away.

Stringy vegetables, bones and fibrous materials can become trapped inside bends and junctions in your plumbing.

Problem foods include:

• Celery
• Onion skins
• Corn husks
• Seafood shells
• Bones

Protect your plumbing by

Scraping plates and pans into the bin before rinsing them.

Cotton Buds and Cotton Balls

Cotton products absorb water rather than breaking down.

Once trapped inside pipes they easily catch other debris moving through the system.

The simple fix

Dispose of cotton products in the bin, not the toilet or sink.

Why Prevention Matters

Blocked drains often start with small everyday habits.

At first you may notice:

• Slow draining sinks
• Gurgling noises
• Water pooling around drains
• Unpleasant smells

Without attention, minor issues can eventually turn into overflowing drains, poor drainage, burst pipes or sewer backups.

Preventing plumbing problems is almost always cheaper and easier than repairing them.

Simple Ways to Help Prevent Blocked Drains

You do not need expensive products to protect your plumbing.

Small habits can make a big difference:

• Use sink strainers
• Avoid pouring oils into sinks
• Wipe greasy pans before washing
• Flush only toilet paper
• Clean drain guards regularly
• Scrape food scraps into the bin first
• Arrange plumbing inspections if drains repeatedly run slow

Prevention Is Easier Than Repairs

Most plumbing emergencies start with everyday habits people think are harmless.

Being careful about what goes down your drains can help prevent expensive repairs, unpleasant smells and unnecessary stress.

A little prevention now can save a major blockage later.
