CCTV drain camera (plumbing)

Last updated

CCTV drain cameras, also known as sewer cameras or pipe inspection cameras, are a line of waterproof, high definition cameras that have become a widely popular technology in the plumbing profession. These cameras are advanced diagnostic tools that allow plumbers to execute plumbing inspections, called CCTV Drain Surveys [1] with heightened accuracy.

These cameras can vary; the main difference being the size of the pipe the camera ca inspect. The total distance they can travel within the pipeline is also a common difference between models. [2]

Purpose

CCTV drain cameras are used to uncover any damages or obstructions within the plumbing system. [3] They provide a non-invasive and efficient way to assess the internal condition of drainage pipes and sewer systems, ensuring that issues are accurately identified and addressed without the need for disruptive excavation or guesswork.

These advanced cameras are equipped with high-resolution imaging and flexible cables that allow them to navigate through various pipe sizes and shapes, capturing clear, real-time footage of the inside of the drainage network. As modern-day technology, they are specifically designed for surveying and assessing the working condition of water pipes and sewer lines, [4] making them an invaluable tool for both residential and commercial applications.

In the plumbing world, CCTV drain cameras are commonly used to detect and locate potential problems, such as debris buildups, collapsed pipe sections, root infestations, and pipe offsets. By providing a clear visual of the interior of the drainage system, these cameras help professionals diagnose issues accurately and plan effective solutions. [5] This level of precision eliminates the need for trial-and-error methods, reducing repair time and cost for property owners.

Moreover, CCTV inspections are often conducted as part of routine maintenance to prevent serious drainage problems from developing. Early identification of minor defects, such as hairline cracks or corrosion, allows plumbers to recommend proactive repairs, extending the lifespan of the drainage system. Consequently, CCTV drain cameras contribute significantly to maintaining the overall health and functionality of plumbing networks.

Usage

The camera, attached to a long, flexible cable, is fed through an access point on the property, such as a drain cover or cleanout. It is then carefully maneuvered through the pipes until it reaches the point of damage or obstruction. As the camera moves through the plumbing system, the captured footage is transmitted directly to a monitor or screen, giving the plumber a real-time view of the affected area. This live feed allows the professional to inspect the condition of the pipework, identify issues, and determine the exact location of any problem spots, such as blockages, cracks, or root intrusions.

The camera can also be used in tandem with a plumber’s snake (also known as a drain auger). After the camera has pinpointed the position of a blocking object, such as a buildup of debris or a foreign object, the plumber’s snake can be fed into the same access point. The snake's flexible design allows it to navigate bends and tight spaces within the pipe, where it can then be used to break up or remove the blockage. This combination of tools ensures a highly efficient process, minimizing disruption and avoiding unnecessary excavation or pipe removal.

Additionally, CCTV drain cameras are often paired with hydro-jetting equipment. Once the camera has identified the extent of the obstruction, high-pressure water jets can be used to thoroughly clean the pipe interior, effectively removing any stubborn residues or buildup. This step is especially useful for clearing out grease, scale, or other accumulations that may restrict water flow.

Through the use of these modern technologies, plumbers can achieve accurate diagnoses and perform targeted repairs, reducing the need for extensive digging or structural disruptions. The combination of CCTV drain cameras, plumber’s snakes, and hydro-jetting provides an integrated solution to maintaining and repairing plumbing systems efficiently and cost-effectively.

Plumbing is any system that conveys fluids for a wide range of applications. Plumbing uses pipes, valves, plumbing fixtures, tanks, and other apparatuses to convey fluids. Heating and cooling (HVAC), waste removal, and potable water delivery are among the most common uses for plumbing, but it is not limited to these applications. The word derives from the Latin for lead, plumbum, as the first effective pipes used in the Roman era were lead pipes.

A fitting or adapter is used in pipe systems to connect sections of pipe or tube, adapt to different sizes or shapes, and for other purposes such as regulating fluid flow. These fittings are used in plumbing to manipulate the conveyance of fluids such as water for potatory, irrigational, sanitary, and refrigerative purposes, gas, petroleum, liquid waste, or any other liquid or gaseous substances required in domestic or commercial environments, within a system of pipes or tubes, connected by various methods, as dictated by the material of which these are made, the material being conveyed, and the particular environmental context in which they will be used, such as soldering, mortaring, caulking, plastic welding, welding, friction fittings, threaded fittings, and compression fittings.

<span class="mw-page-title-main">Pipefitter</span> Tradesman who works with mechanical pipes

A pipefitter or steamfitter is a tradesman who installs, assembles, fabricates, maintains, and repairs mechanical piping systems. Pipefitters usually begin as helpers or apprentices. Journeyman pipefitters deal with industrial/commercial/marine piping and heating/cooling systems. Typical industrial process pipe is under high pressure, which requires metals such as carbon steel, stainless steel, and many different alloy metals fused together through precise cutting, threading, grooving, bending, and welding. A plumber concentrates on lower pressure piping systems for sewage and potable tap water in the industrial, commercial, institutional, or residential atmosphere. Utility piping typically consists of copper, PVC, CPVC, polyethylene, and galvanized pipe, which is typically glued, soldered, or threaded. Other types of piping systems include steam, ventilation, hydraulics, chemicals, fuel, and oil.

<span class="mw-page-title-main">Trap (plumbing)</span> Plumbing device

In plumbing, a trap is a U-shaped portion of pipe designed to trap liquid or gas to prevent unwanted flow; most notably sewer gases from entering buildings while allowing waste materials to pass through. In oil refineries, traps are used to prevent hydrocarbons and other dangerous gases and chemical fumes from escaping through drains. In heating systems, the same feature is used to prevent thermo-siphoning which would allow heat to escape to locations where it is not wanted. Similarly, some pressure gauges are connected to systems using U bends to maintain a local gas while the system uses liquid. For decorative effect, they can be disguised as complete loops of pipe, creating more than one U for added efficacy.

<span class="mw-page-title-main">Grease trap</span> Trap designed to intercept most greases and solids before they enter a wastewater disposal system

A grease trap is a plumbing device designed to intercept most greases and solids before they enter a wastewater disposal system. Common wastewater contains small amounts of oils which enter into septic tanks and treatment facilities to form a floating scum layer. This scum layer is very slowly digested and broken down by microorganisms in the anaerobic digestion process. Large amounts of oil from food preparation in restaurants can overwhelm a septic tank or treatment facility, causing the release of untreated sewage into the environment. High-viscosity fats and cooking grease such as lard solidify when cooled, and can combine with other disposed solids to block drain pipes.

<span class="mw-page-title-main">Sewer dosing unit</span>

A sewer dosing unit (SDU) is a plumbing device to allow effective sewage disposal with low liquid-flow rates. With a global emphasis on water saving, many new buildings and renovations are seeing the installation of water saving fixtures such as low flow shower heads and low flush toilets. With the decrease in wastewater flows problems are arising from waste solids not being carried completely to the main sewers, often causing blockages.
