Drain Clearance Jargon Explained: Drain Rodding, Jetting, Testing, Tracing

The problems caused by blocked pipes are varied and many. From the backing up of drains to the smells and health risks of standing waste water, ensuring that your pipework is clear from obstruction is the best way to avoid these unwanted headaches.

However, knowing what type of drain clearance is going to be most suited to your needs isn’t always easy – particularly if you are unsure as to the location and severity of the blockage. Here are a few handy tips to point you in the right direction…

Hydro jetting sewer cleaning method

Drain Rodding

When the obstruction is in external drains and sewers, drain rodding for clearance is a good option. Screwing metre-long sections of a rigid yet manoeuvrable rod together, this method works by pushing the rod through the pipework from an access chamber, and can be adapted to allow for piercing and grabbing debris also.

Drain rods are usually made from specially developed polypropylene, giving the right balance of strength and flexibility, although more heavy duty options made from steel are also common. The rod is pushed through the chamber using a twisting motion to free obstructions.

 

Drain Jetting

Another common method for clearing larger, external sewers and drain networks, high power drain jetting is often the most effective. Water is sprayed through tubing at up to 5,000 psi, providing enough power to break down obstructive materials, such as grease, fats, leaves and other waste debris.

Drain jetting is particularly suited to clearing sand deposits, and provides a clean and highly efficient method of clearing most blockages from your drains.

 

Testing/Surveying

If the cause or location of your blockage isn’t obvious, it is often unclear as to what the best course of action should be in rectifying it. There are a number of tests and checks you can have carried out to determine this, all available from leading drainage companies, such as Express Drainage Solutions.

–      CCTV Drain Surveys. Using advanced technology and equipment, these surveys send CCTV down into pipework, with images monitored above by a drainage expert. This will give the clearest indication possible of the extent and location of the blockage, while also helping to identify other damage.

–      Dye Testing. Most often used to spot leaks, dye testing adds harmless colouration to the water supply, allowing to check the flow of waste water through the system as well as to verify which outlets stem from which drains.

–      Drain Tracing. Often used alongside CCTV surveys, tracing uses locators such as sonar or metal detectors to trace the layout of your drainage system. This can help you to understand the makeup of your drains and sewers, identifying potential problem areas or concealed sections that may be causing problems.
