Signs of a Collapsed Drain: How to Spot and Fix the Problem

Identifying Common Signs

If you suspect that your drain may have collapsed, there are several signs that you can look out for. In this section, we will discuss the most common signs of a collapsed drain and how to identify them.

Unusual Odours

One of the most common signs of a collapsed drain is an unpleasant odour coming from your drains. If you notice a sewage-like smell around your drain cover or inside your home, it could be an indication that there is a blockage or damage in your drain pipe.

This odour is caused by backups and blockages that occur when wastewater cannot flow properly through the pipes.

Slow Drainage

If your sinks, toilets, or showers are slow to drain, it could be a sign of a collapsed drain. When a drain is damaged or collapsed, water cannot flow through the pipes as it should, causing blockages and slow drainage.

If you have tried clearing the blockage but the problem persists, it may be time to call a professional to inspect your drain.

Water Backup

Another sign of a collapsed drain is water backup in your sinks, toilets, or showers. If you notice that water is backing up into your sink or shower when you flush the toilet, it could be a sign that your drain pipe is damaged or collapsed.

This backup occurs when wastewater cannot flow through the pipes as it should, causing it to overflow into other areas of your home.

Physical Indicators

If you suspect that you have a collapsed drain, there are several physical indicators that you should look out for. These include ground movement and subsidence.

Ground Movement

One of the most obvious physical indicators of a collapsed drain is ground movement. If you notice that the ground around your property is sinking or moving, it could be a sign that your drain has collapsed.

This is because the weight of the soil is no longer being supported by the drain, causing the ground to shift.

Subsidence

Another physical indicator of a collapsed drain is subsidence. This is when the ground around your property sinks or collapses.

Subsidence can be caused by a variety of factors, including a collapsed drain. If you notice that your property is sinking or that there are cracks in your walls or floors, it could be a sign that your drain has collapsed.

It is important to note that ground movement and subsidence can be caused by a variety of factors, and may not necessarily be the result of a collapsed drain. If you suspect that your drain has collapsed, it is important to contact a professional drainage company to carry out an inspection. They will be able to identify the cause of the problem and recommend the best course of action.

Audible Clues

When it comes to identifying a collapsed drain, there are several audible clues that you should be aware of. These sounds can indicate that there is a problem with your drainage system and that you need to take action to prevent further damage.

Gurgling Sounds

One of the most common audible clues of a collapsed drain is gurgling sounds. You may hear these sounds coming from your drains or toilet when you flush them.

This is caused by air being trapped in the pipes due to a blockage or collapse. As the water tries to pass through the damaged section of the pipe, it creates a vacuum that sucks in air, causing the gurgling sound.

If you hear gurgling sounds coming from your drains or toilet, it’s important to take action immediately. This could indicate that there is a blockage or collapse in your drainage system, which could lead to further damage if left untreated.

To prevent further damage, you should contact a professional drainage company to assess the problem and provide a solution. They may need to use CCTV cameras to inspect the pipes and identify the location of the blockage or collapse.

Professional Inspection Techniques

If you suspect that your drain has collapsed, it is important to have it inspected by a professional. There are various techniques that a professional can use to inspect your drain and determine whether it has collapsed. In this section, we will discuss two common inspection techniques: CCTV drain surveys and dye testing.

CCTV Drain Surveys

CCTV drain surveys are a popular method of inspecting drains. This technique involves using a small camera attached to a flexible rod to inspect the inside of your drain.

The camera sends a live video feed to a monitor, allowing the professional to see the inside of your drain in real-time.

During a CCTV drain survey, the professional will look for signs of damage, such as cracks, fractures, or collapsed sections. They will also be able to identify any blockages or obstructions that may be causing problems with your drain.

If the professional identifies any issues during the CCTV drain survey, they will be able to provide you with a detailed report of their findings. This report will include recommendations for repairs, such as drain relining or excavation.

Dye Testing

Dye testing is another technique that can be used to inspect your drain. This technique involves injecting a coloured dye into your drain and then monitoring the flow of the dye to identify any issues.

During a dye test, the professional will inject the dye into your drain and then monitor the flow of the dye using a camera.

If the dye flows smoothly through your drain, this indicates that there are no issues. However, if the dye becomes trapped or does not flow smoothly, this may indicate that there is a blockage or collapsed section in your drain.

Dye testing can be a useful technique for identifying the location of blockages or collapsed sections in your drain. However, it may not be as effective as CCTV drain surveys for identifying the extent of damage or providing recommendations for repairs.

Preventative Measures and Maintenance

Taking preventative measures and maintaining your drains can help reduce the risk of a collapsed drain. Here are some tips to keep your drains in good condition:

• Regular cleaning: Regularly cleaning your drains can help prevent blockages and build-up of debris. You can use a plunger or drain snake to clear any clogs or hire a professional to perform a deep clean.
• Proper disposal: Avoid pouring grease, oil, and other substances down your drains as they can solidify and cause blockages. Dispose of these substances in the trash instead.
• Tree root management: Tree roots can grow into your drain pipes and cause damage. To prevent this, avoid planting trees near your drainage system and regularly trim any nearby trees.
• Professional inspection: Have a professional inspect your drains regularly to identify any potential issues before they become major problems.
