Sewer Shaft and Network Inspection with a Camera

Sewer Camera Inspection — When You Need to See the Exact Cause of a Blockage

When a sewer blocks, the first thought is often, “Let’s clean it and the water will pass.” Sometimes that is true. But if the same problem returns after a few days or weeks, something else is happening. Either the pipe was not fully cleaned, or a hidden defect remains inside it.

This is when a sewer camera inspection becomes essential. It is not diagnosis for its own sake. A camera is needed when guesswork is no longer worthwhile. A manhole may look clean and water may still pass to some degree, while the pipe contains a sunken section, roots, deposits, a broken wall, incorrect fall, or a foreign object.

An experienced plumber can infer a great deal from the symptoms, but without seeing inside the pipe there is not always a precise answer. Sewer lines run underground, behind walls, across yards, or between manholes. Before excavation, demolition, or major work begins, it is better to know exactly what is happening inside.

When Is a Sewer Camera Inspection Needed?

Camera inspection is most often required when the sewer blocks repeatedly. A single blockage may be accidental—for example, a wet wipe, greasy waste, or another object has entered the pipe. But a recurring problem is a warning sign.

A common pattern is that the pipe is cleaned, the water begins to flow, and everyone assumes the job is finished. A few days later, exactly the same problem returns. The cause may be deposits left inside the pipe, an invading root, a sunken section, or mechanical damage. Ordinary cleaning opens a path, but it cannot show what caused the blockage.

Inspection is also important when a sewer manhole in the yard fills, water drains slowly, an unpleasant smell appears, there is dampness in a basement, or a particular section of the network behaves unusually. It is equally useful before a new property is handed over, an older house is purchased, or renovation begins—especially when nobody knows the condition of the existing sewer network.

What Can the Camera Show Inside a Pipe?

A camera provides a real-time view inside the pipe. This saves time and money because the problem is no longer based only on assumptions.

A camera can reveal:

• Grease and deposits accumulated inside the pipe.
• Roots that have entered the pipe.
• A broken or cracked section.
• A sunken pipe where water collects.
• Incorrect fall.
• Construction debris or another foreign object.
• A poorly made connection.
• A narrowed section inside the pipe.

Most of these problems are completely invisible from the outside. If a section of pipe has sunk, water collects there. Waste then accumulates in the same place and the pipe blocks again. No matter how many times it is cleaned, the underlying cause remains.

The same applies to roots. Once a root enters the pipe, it traps waste. Everything may appear normal outside while the network gradually closes from within.

Why Inspect Before Excavating?

The traditional approach was simple: if there is a blockage somewhere, start digging. Excavation is sometimes unavoidable, but it should not begin without knowing the exact cause. One part of the yard may be opened only to discover that the problem is elsewhere; a wall may be broken even though the defect lies much farther away.

A sewer camera inspection reduces these risks. First, we determine where the problem is and what type of problem it is. If cleaning is required, the pipe is cleaned. If a specific section must be repaired, the work can be planned much more accurately.

This is especially important in private houses, apartment courtyards, commercial properties, hotels, restaurants, and industrial sites. Every unnecessary excavation or demolition means lost time, noise, interrupted operations, and additional cost.

A camera does not guarantee that no repair will be needed. The difference is that you know exactly why the repair is necessary and precisely where the work should be carried out.

How Is the Sewer Network Inspected with a Camera?

First, a suitable access point is chosen. It may be a sewer manhole, a technical access point, a yard chamber, or another location from which the camera can enter the pipe. If the network is heavily contaminated, partial cleaning may be necessary first so that the camera can pass and provide a clear image.

The camera is then inserted into the pipe and advanced slowly. The specialist watches the internal condition on a screen. A clean pipe is useful information in itself. If a problem appears, its location and nature can be assessed.

Experience is critical because the image must be interpreted correctly. What appears insignificant to an untrained eye may immediately show a specialist that a section has sunk, a connection is poorly seated, or the pipe wall is damaged.

A proper inspection does not end when the camera is removed. The specialist must explain why the problem developed and recommend the correct solution—high-pressure jetting, mechanical cleaning, replacement of a section, or another intervention.

Who Most Often Needs This Service?

Sewer camera inspection is useful for residents of private houses and apartment buildings, as well as businesses, restaurants, cafés, hotels, car washes, industrial sites, and any property where sewer failure would create a serious disruption.

In private houses, it is often used to inspect the yard network—for example, when a manhole fills, water backs up, or the condition of an underground pipe is unknown.

In apartment buildings, the service is invaluable when a specific section of the shared network blocks repeatedly and residents cannot determine the source.

Inspection is especially valuable in commercial properties. In a restaurant or hotel, a blocked sewer is more than a technical problem: work may stop, odours may develop, interiors may be damaged, and customers may be affected. Knowing the exact cause is crucial.

Camera Inspection Before or After Cleaning?

The procedure may be useful at either stage. If a pipe is completely blocked and the camera cannot pass, it is cleaned first. The camera can then verify whether the underlying cause remains. This is often the best approach when the problem recurs.

A camera may reveal more after cleaning. While the pipe is full of debris, important details can be hidden. Once clean, it becomes clear whether the pipe is damaged or was simply contaminated.

In other cases, the camera is inserted first, identifies the blocked section, and allows cleaning to be targeted accurately. The plumber should decide the correct sequence on site.

What Should You Know Before Calling?

If you know where the sewer manhole or inspection chamber is, that is a good start. If you do not, it is not a problem, although the specialist may need more time on site.

It is helpful to explain how often the network blocks, when the issue began, where water collects, whether cleaning has already been attempted, and which section concerns you.

Do not worry if the property is old and no drainage plan exists. This is very common. Pipes in many houses and yards were installed without an accurate record, making camera inspection even more valuable.

Sewer Camera Inspection with Chalicha

Chalicha provides camera inspection of sewer manholes and networks whenever the real condition inside a pipe must be seen instead of guessed.

If the sewer blocks frequently, a manhole fills, water drains slowly, an odour appears, or you suspect pipe damage, camera inspection is the best first step. It identifies whether you are dealing with deposits, roots, a broken section, or incorrect fall.

From the outside, sewer problems often look identical: water does not drain. Inside the pipe, however, the causes can be completely different. A camera reveals that difference. Once the cause is known, the correct solution becomes much clearer.
