Sewer Backups: Causes

As we have already mentioned earlier that it is important to acknowledge that sewer backup in a commercial property is triggered due to many reasons.

Tree roots

The trees that add pleasantness to the surrounding environment can be fatal for your business units because their growing roots can wrap around the pipeline and break it. This will lead to pipe backups as the wastewater will not be able to drain away from your property, and will lead to flooding, and unpleasant odor etc.

Structural flaws

Sewage backup can be caused due to installation and structural flaws for instance misaligned pipes, pipe holes and collapses, and sag in the pipes.

Flushing mistakes

Often terrible flushing mistakes lead to sewer backups. For instance, when solid objects are flushed down the drain it has a high chance of blocking the sewer line. This can be caused by the visitors, employees, and customers who enter the premises and dump their trash down the drain.

Heavy rains

Another reason that can causes sewer backup is heavy rains. If the sewer system in the property cannot drain the excess water, then it can overflow due to backup and will flood the property.

If you spot any of these problems then it is best to consult professional plumbers to fix the issues. In case your property is on the verge of getting flooded or is already flooded, give a call to an experienced plumber. If you live in Mandurah, and facing a similar situation, then call a leading commercial plumber in Mandurah.
