Why do drains block?

Blocked drains are a common and annoying problem experienced at some stage in most homes and businesses. There are a number of reasons that drains will block and often the immediate symptom of the blockage is treated and not the underlying cause is rectified. The most common causes of blockages are:

Foreign objects or debris

Outside drains may become blocked after storms or heavy downpours collecting leaves, dirt and other matter that can build up and block drains. Blocked drains during heavy storms are very common as they are generally not designed to manage large volumes of water. Blocked outside drains can cause flooding and damage to property.

With the dramatic rise in popularity of do-it-yourself (DIY) repairs and home renovations, there has been an increase in poorly installed plumbing and drainage pipes. Pipes may become misaligned or completely collapse if installed incorrectly. Choosing the right pipes is an integral part of any plumbing job and so it is vital that have a full understanding of the pipework required to do the job. Incorrect installation is not only dangerous but could also damage other parts of your or your neighbours’ property, causing great expense.

Water doesn’t flow uphill and drainage is all about gravity. Incorrect pipe installation with inadequate falls could contribute to the build-up of particles and debris and could eventually result in blocked drains. It is vital that pipes are installed correctly to ensure adequate water flows. Drains become blocked for a variety of reasons, so it is important to understand what the underlying cause of blocked drainage is. Blockages can build up over time and you may get some early warning signs that there are some obstructions to the water flow. These include gurgling sounds after you flush a toilet, the water level in your sink or bath draining slowly, and bad smells from sinks or drains.

Some blockages can be easily cleared using a plunger; however treating the symptom may not address the underlying causes of drain blockages.
