Blocked Drains

Blocked drains are a huge inconvenience for home owners and occupants of buildings. There are various reasons why drains block up and there are many ways to fix such a problem. However, it is common for the immediate symptom of the blockage to be treated but not the underlying cause. Unfortunately, some people come across blocked drains more often than others. At Hall Plumbing we understand how frustrating this can be, so we are here to help you. It is important to be aware of what causes blocked drains so that future issues can be prevented.

1- Foreign Objects

This is one of the most common causes of blocked drains and one that can be easily avoided. Foreign objects such as hair, soaps, fats, food build up and sanitary wipes can be caught in the pipeline. The blockage may not occur right away, but over time toilet paper etc will collect, thus slowing down the flow of the drain and creating a serious blockage.

2- Incorrect Installation 

As the popularity of DIY repairs and renovations rise, there has been an increase in poorly installed plumbing. Choosing the correct pipe and having an understanding of drainage is paramount. More often than not the pipes can be misaligned, not have adequate fall or completely collapse. Without proper fall, the pipe has restricted water flow which leads to a build up of waste causing a blocked drain. It is important to use a licensed plumber to ensure you get the job done correctly.

3 – Heavy rains or storms

Blocked drains during heavy downpours are very common in storm water systems. The collection of leaves plus a large volume of water can quickly cause blockages which could lead to flooding of the property. It is important to regularly clean out gutters and downpipes in preparation for winter.

4 – Root intrusion/Broken Pipe

Another cause of blocked drains can be from broken pipes. Broken pipes can occur from poor installation, age and root intrusion. Older homes in Australia are notorious for blocked drains as a result of tree root intrusion.This is because old sewer lines were made using clay and joined together with mortar and rubber rings. Over time the mortar crumbles and rubber rings perish. This makes as a perfect entry point for tree roots searching for water. Once the roots have found sufficient water and nutrition, they will grow along the inside of the pipe. If left untreated, this can cause significant problems and certain sections of the drain will need to be replaced.

If you suspect a blocked drain, ask Hall Plumbing about our CCTV Drain inspections. Our survey takes a video recording of your drain to determine what your needs are. More often than not, root intrusion can be dealt with by Hydro-jet cleaning or mechanical drain cleaning. Only in severe cases would we recommend section replacements.
