How to Keep Drains and Toilets Clear: Simple Tips to Prevent Blockages

Blocked drains and toilets are one of the most common maintenance problems in rental properties. Fortunately, many of these issues can be avoided by following a few simple everyday habits.

Whether it’s flushing the wrong items down the toilet or pouring cooking oil into the kitchen sink, small actions can lead to expensive repairs and unnecessary inconvenience. By taking care of your drains, you can help keep your home running smoothly and reduce the risk of blockages.

Here are some practical tips every resident should know.

Follow the Three Ps Rule

A good way to protect your toilet is to remember the Three Ps.

Only flush:

• Pee
• Poo
• Toilet paper

These are the only items designed to break down properly in the drainage system.

Anything else should be placed in a bin rather than flushed down the toilet.

Never Flush Wet Wipes

Don’t be misled by the word “flushable.” Many wet wipes don’t break down as easily as toilet paper and can build up inside pipes over time.

Instead, they can become trapped inside pipes, where they collect other waste and eventually cause serious blockages.

To help protect your plumbing, always place used wet wipes in a bathroom bin instead of flushing them away.

Items That Should Always Go in the Bin

Many items we use every day should never be flushed, as they can cause blockages and damage to the drainage system.

These include:

• Wet wipes
• Sanitary products
• Nappies
• Cotton buds
• Cotton wool
• Dental floss
• Hair
• Condoms

Keeping these items out of the drainage system helps prevent blockages and protects the wider sewer network.

Take Care of Your Kitchen Drains

Kitchen sinks are another common place where blockages develop.

One of the biggest causes is pouring fat, oil and grease down the sink. Although these may seem harmless when warm, they harden as they cool and can stick to the inside of your pipes.

Instead:

• Allow cooking oil or grease to cool.
• Pour it into a suitable container.
• Dispose of it in your household bin.

Before washing dishes, scrape leftover food into your food waste bin or general waste bin instead of rinsing it down the sink.

These simple habits can help keep your kitchen drains flowing freely.

Run Hot Tap Water After Washing Up

After you’ve finished washing up, it’s a good idea to run hot tap water down the kitchen drain for a short time.

This can help rinse away small amounts of grease left behind from everyday cooking.

However, avoid pouring boiling water directly into plastic or PVC pipes, as extremely hot water may damage some types of plumbing.

Keep Your Drains Fresh

Regular maintenance can help keep drains clean and reduce unpleasant smells.

From time to time, you may wish to use a drain-safe cleaner according to the manufacturer’s instructions.

Alternatively, where appropriate, a simple baking soda and vinegar rinse can help freshen your drains as part of routine maintenance.

Always follow product instructions carefully and never mix different cleaning chemicals together.

Keep Outdoor Drains Clear

If you’re responsible for outdoor areas around your property, don’t forget to check external drains from time to time.

Leaves, litter and garden waste can build up over time, especially during windy weather.

Removing this debris allows rainwater to drain away properly and reduces the risk of blocked drains or surface water pooling.

Dispose of Household Waste Responsibly

Some household waste should never be poured down drains.

Items such as:

• Paint
• Engine oil
• Solvents
• Chemicals

should be taken to your local recycling or household waste centre for safe disposal.

Unused medicines and syringes should be returned to your local pharmacy instead of being flushed or poured down the sink.

Know the Early Warning Signs

Drain problems often start with small warning signs.

Look out for:

• Slow-draining sinks
• Toilets that are difficult to flush
• Gurgling sounds from drains
• Unpleasant smells coming from sinks or toilets

If you notice any of these issues, report them as soon as possible.

Taking action early can help prevent larger maintenance problems.

Avoid Unnecessary Repair Charges

Looking after your drains not only helps protect your home but may also save you money.

Blockages caused by flushing unsuitable items or misusing drains may be considered the resident’s responsibility and could result in repair charges.

Following the simple tips in this guide can help you avoid unnecessary costs while keeping your plumbing in good condition.

Final Thoughts

Keeping your drains and toilets clear doesn’t require much effort, but the benefits can be significant.

By remembering the Three Ps, disposing of waste correctly, avoiding fats, oils and grease down the sink, and reporting problems early, you can help prevent blockages before they happen.

Small everyday habits make a big difference—not only for your home but also for the environment and the wider drainage system.
