Blocked Drainage: Causes Of Blocked Drainage

Blocking drainage can be a major inconvenience for homeowners or building managers. If the drain in the facilities is blocked, the water in the sink and shower will drain slowly. When unloading, the water in the toilet can rise and the cannons can overflow. As water is retained and does not flow continuously, it can cause bad smell from the drain. The service of an experienced plumber is convenient if it blocks the drain. It will diagnose and correct the problem correctly. Several factors can casue sewer pipe relining Brisbane.


 When washing dishes, fats and greases usually come down from the kitchen sink. The grease is trapped inside the pipes without going down the drain with water. Fat accumulates over time, cloggingthe drains. This problem can be avoided by not pouring fatty substances into the sink. Instead, it can cool the fat, harden it, scrape it and throw it away.

 Green leaves

 In autumn, the leaves fall from the tree and accumulate easily in the pipes, which can block the drainage. Therefore, it is important to collect the leaves at the facility and properly dispose of them in the trash. The root of the tree is also the source of the drains. The roots are usually attracted to moisture and move towards the pipes that carry wastewater. Then break the pipe to get to the water. When this happens, the roots block the drain.

 Foreign goods

 Foreign matter may enter and accumulate in the drain, causing the drain to clog. Items such as soap or jewellery can fall through the sink and sanitary items can be washed from the toilet to block drains. The hair also drains easily in the pipes and becomes blocked. Therefore, it is important to place a trap in the sink so that the debris does not fall into the drain. Tissue paper should be washed with tissue paper and other sanitary items and objects should be thrown away.


 When water is discharged from the pipes, air enters from the vents. If there is enough air, water and debris are properly discharged from the pipe. If there is not enough air in the vents, residual water accumulates and becomes blocked. Therefore, there should be no blockages in the roof vents. Sometimes due to storm, you have to experience blocked stormwater drains.

 Steep slopes

 The slope of the drainage pipe also affects the efficiency with which the waste enters the main sewer or if the slope is too steep, the water flows quickly, leaving residues, and after a certain time, the residues accumulate, clogging the pipe. On the other hand, if the slope is too soft, the debris and water do not drain completely, but instead accumulate in the pipe, obstructing the drain.
