Sewer systems are fond of clogging up. This is because there is a constant build-up of waste within the pipes. A blockage in the main sewer line may at first pose no serious threat but in essence, it’s a ticking time bomb waiting to explode. If corrective measures are not taken the entire drainage system including that of the house may suffer the consequences brought about by a single clog. Locating clogs in the main sewer line is not as easy as finding out the source of the clog in a blocked bathroom drain and may need the assessment of a professional. In the event that the affected area is identified the plumber will have to take further precautions to ensure that the clog is safely removed. This article highlights a few methods that plumbers use when unblocking a blockage in the main sewer line.

Sewer line Assessment

Before the plumber brings out any tools he has to carry out an assessment in order to determine where the blockage is. The assessment will also help the plumber to know what has caused the clog thereby making it easy to know the type of tools needed. A sewer line can clog due to many reasons such as a foreign material like the roots of trees, excessive build-up of materials in one section of the pipe and at times the pipe might be damaged.

Most assessments are performed through the use of drain cameras which are driven through the drainage system to detect any of the issues listed above. Depending on the results of the assessment a plumber can use the following methods to remove a clog from the sewage system;

How do Plumbers Unblock a Blockage in Main Sewer Line

High-Pressure Water Jetters

These are basically long hose pipes with nozzles at the tips. This device uses the high pressure from the water to clear out clogs from the sewer line. In as much as they are new in the market, most plumbers prefer using water jetter because it is very easy to use and is an efficient drain unblocker. To clear a clog with this equipment simply insert the water jetter in the suspected sewer line and turn on the water delivery system.

The mechanism in place ensures that water is delivered at very high pressure. This breaks the clogs into simple particles which are then washed away. This method of unblocking sewer lines is preferred because it does not damage the pipes and in addition, it leaves the pipes squeaky clean. High-Pressure Water Jetters can also be paired with other plumbing tools such as cameras to get better results.

Electric Augers

Electric augers use motors that are attached to a long steel cable. The end of the steel is fitted with blades that are continuously rotated by the motor. After the auger is introduced into the clogged system the blades will cut through anything that may be blocking the pipes. Depending on the diameter of the drain being unblocked, the plumber can pick a blade size that best fits the task requirements. 

It is important to note that electric augers only work best when the proper maneuver is achieved; failure to which the blades may damage the pipes. Once the clog has been broken down water can be passed to completely wash away any residue that may still be remaining.

When dealing with the main sewer line, it is good to hire a professional to handle the job. Sewer lines are filled with poisonous gases which may be toxic if inhaled. Some of these gasses may also be highly flammable so attempts to open the main sewer line on your own may turn out to be disastrous. Hiring a fully licensed sewer company is definitely the only way to go about the mainline blockage.
