How to Clean Drains Outside

External drain blockages can have a knock-on effect on your property’s plumbing system, so it’s best to stay on top of drain cleaning and maintenance to avoid any issues down the line.

Without regular drain maintenance, you may experience unpleasant smells, slow drainage, raised water levels, standing water around the drain cover and repeated blockages inside the property.

If you are searching for how to clean drains outside, the honest answer is: start with prevention, remove visible debris, flush the drain carefully and know when to stop. Some minor outdoor drain cleaning can be handled yourself, but a blocked, overflowing or sewage-smelling outside drain may need a professional drainage engineer.

Why do outside drains become blocked?

External drain blockages stem from the main drains outside a property, so the maintenance involved differs slightly from the upkeep needed inside.

Some outside drain problems are caused by materials entering the drain from outside. Others begin inside the property and build up slowly until they affect the external drainage system.

Common causes of outside drain blockages include:

• Leaves, mud, soil and garden debris.
• Litter or loose objects around the drain cover.
• Cooking oil, fat and grease.
• Food waste from kitchen sinks.
• Hair, soap scum and bathroom residue.
• Wet wipes, paper towels, tampons and sanitary products.
• Blocked gutters washing debris into the drainage system.
• Tree roots entering cracked or damaged pipework.
• Collapsed, cracked or displaced drain pipes.

As we’ve already touched upon, your external drains will bear the brunt of any internal drain misuse. With this in mind, proper waste disposal is a simple yet effective way to lower the risk of major external drain issues.

 

Build good disposal habits

Oil, hair, soap scum, and food waste are the most common causes of internal drain blockages, as well as non-flushable items like paper towels, wipes, and tampons. If these items make it through your property’s system, then they’ll inevitably begin to block your external drain.

It’s best to keep these items as far away from your drainage system as possible by focusing on the correct disposal methods, such as putting used cooking oil in the bin and using a plughole strainer for your kitchen and bathroom.

Try to avoid putting the following down sinks, toilets, showers and baths:

• Cooking oil, fat and grease.
• Food scraps.
• Coffee grounds.
• Wet wipes.
• Paper towels.
• Sanitary products.
• Hair and soap residue.

A small change inside the property can make a noticeable difference outside. A plughole strainer, a bin for bathroom waste and a sealed container for used cooking oil can all help reduce what reaches the drainage system.

 

Clear the area around the outside drain

Prevention is better than cure, so it’s time to grab a rake, some grass trimmers, and a waste bag. External drain blockages can be caused by general debris like leaves, dirt, litter, and even tree roots.

The best way to avoid this is to inspect the area regularly to keep it clear and dispose of any debris. Another tip is to inspect your external drain for cracks; no matter how small, roots can find their way in and create major structural issues.

You should also keep roots and garden foliage as far away from your drain pipes as possible. We know drains aren’t the most picturesque part of your property, but you’ll unfortunately have to put that plant somewhere else!

Make sure to check your external drains more often in autumn, too, as the change in weather and falling leaves can increase the risk of blockages.

 

Install a drain cover

If you don’t have one already, we recommend investing in a drain cover to protect your pipes. Drain covers can stop any obstructions, including leaves, branches, and litter, from falling into your drain system.

You can install a drain cover yourself, provided you’re equipped with the right tools. However, we suggest contacting a drain specialist if you don’t feel confident taking a DIY approach.

Our team is always on hand to provide advice, and we can even check that you have the right drain cover for your specific type.

Flush your external drains

It’s a good idea to flush your drains every few weeks to reduce the risk of future blockages. You can flush your internal drains as well as the external ones for the best results.

Simply fill up a large bucket of hot water and tip it down the drain, creating a strong stream. This should push any loose debris and accumulated dirt or grease through.

If you’re unsure it’s done the job, you can repeat this process. However, if water starts to rise, pool around the drain cover or back up towards the property, stop flushing the drain. This usually means the blockage is deeper in the pipework and forcing more water through could make the problem worse.

 

Keep an eye on your gutters

Your property’s gutters can carry debris, eventually ending up in your external drain system. Take a look at your gutters and do a visual check regularly — can you see any stuck leaves or dirt? If so, this could increase the risk of a drain blockage.

If you’re comfortable cleaning your gutters, you’ll need a ladder, a trowel, a bucket, and a garden hose. Make sure to wear gloves, too! Simply scoop any stuck debris away and give your gutter a good rinse while checking that the water flows away as it should.

Remember, you can always contact professional gutter cleaners if you’d rather not tackle the task yourself.

 

How to unblock a drain outside

If you find your outside drain blocked, you can attempt to unblock it using a drain rod kit, a plunger, and a garden hose to flush the drain. You may also need a strong drain un-blocker solution.

Before you begin, make sure the issue is safe to deal with. If the drain contains foul waste, sewage, sharp objects or heavy standing water, it is better to contact a professional.

Basic outside drain unblocking steps include:

1. Remove the drain cover carefully. Use the right tool and avoid dropping the cover into the drain.
2. Clear visible debris. Remove leaves, silt, mud, litter or other loose material where safe to do so.
3. Flush the drain. Use hot water or a hose to see whether the water begins to move freely.
4. Use drain rods if needed. Work carefully and avoid forcing the rods if you meet heavy resistance.
5. Check the water flow. If the drain still backs up, the blockage may be deeper or caused by pipe damage.

However, it’s important to remember that DIY drain unblocking methods could potentially lead to more complex issues if you use the wrong technique or tools. We always suggest getting in touch with a team of professional drain specialists like ourselves.

 

When should you call a drainage engineer?

You should call a drainage engineer if your outside drain is blocked, overflowing, smelling strongly of sewage or repeatedly causing problems after cleaning.

Call for help if you notice:

• Water overflowing from the outside drain.
• Standing water that will not drain away.
• A strong sewage smell.
• Recurring blocked drains.
• Several drains running slowly at the same time.
• Gurgling noises from sinks, toilets, baths or showers.
• Water backing up into the property.
• Suspected tree root damage.
• Cracked, damaged or collapsed drain pipes.
• DIY cleaning methods not working.

These signs can point to a deeper issue in the drainage system. A professional drainage engineer can inspect the pipework, clear the blockage properly and check whether repairs are needed.

We offer emergency plumbing and drainage solutions across Cheshire, applying over 30 years of expertise to services like drain unblocking, drain cleaning, drain repairs, and even CCTV drain inspections. We use the best equipment for the job and have successfully tackled every drain problem possible.

Whether your outside drain needs a simple clean, a stubborn blockage removing or a full inspection to find the root cause, our team can help.

 

1. Initial assessment

We will ask what you have noticed, where the affected drain is, how long the issue has been happening and whether there are signs of flooding, bad smells, slow drainage or recurring blockages.

 

2. Drain inspection

Our team can inspect the outside drain, check for visible debris and assess whether the problem is likely to be a surface-level blockage or something deeper in the drainage system.

 

3. Drain cleaning or unblocking

Depending on the issue, we may use professional drain cleaning equipment, drain rods or drain jetting to clear the blockage and restore proper flow.

 

4. CCTV drain inspection if needed

If the same drain keeps blocking or we suspect damage, root ingress or a collapsed pipe, we may recommend a CCTV drain inspection. This helps identify the cause rather than just clearing the symptom.

 

5. Repair recommendation

If pipe damage is found, we can recommend the most suitable next step. This may involve drain repairs, drain lining or another repair method depending on the condition of the pipework.

FAQs about cleaning drains outside

How often should I clean my outside drains?

You should visually check your outside drains every few weeks, especially during autumn, after heavy rain or if your property has nearby trees. If you regularly notice leaves, mud or standing water around the drain, it may need more frequent cleaning.

 

Can I clean an outside drain myself?

Yes, minor outside drain cleaning can often be carried out yourself. You can clear visible debris, fit a drain cover and flush the drain with hot water or a garden hose. If the drain is overflowing, smells of sewage or keeps blocking, you should call a professional drainage engineer.

 

Why does my outside drain smell?

A smelly outside drain may be caused by trapped food waste, grease, stagnant water, silt, organic debris or a blockage deeper in the pipework. Cleaning the visible area may help, but persistent drain smells often need professional drain cleaning.

 

What should I not put down my drains?

You should avoid putting cooking oil, fat, grease, wet wipes, paper towels, sanitary products, food waste, coffee grounds, hair and harsh chemicals down your drains. These materials can collect inside the pipework and contribute to outside drain blockages.

 

Can tree roots block outside drains?

Yes. Tree roots can enter outside drains through cracks, gaps or damaged joints. Once inside, they can grow through the pipework and trap waste, silt and other debris. A CCTV drain inspection is usually the best way to confirm root ingress.

 

What if my outside drain keeps blocking?

If your outside drain keeps blocking, the issue may be deeper than surface debris. Common causes include grease build-up, damaged pipework, collapsed drains, poor pipe gradient or tree root intrusion. In this case, professional drain unblocking or CCTV inspection may be needed.

 

Who is responsible for a blocked outside drain?

If the drain is within your property boundary and only serves your property, it is usually your responsibility. If the blockage is in a shared drain or public sewer, your local water company may be responsible. If you are unsure, a drainage specialist can help identify where the problem is likely to be.
