Strange Objects or Debris

Blocked drains can occur when foreign objects or debris such as hair, soap, fats or food build up to quickly. They then become caught between the drainpipe and the pipes that flow underneath the house. This might not fully block the drain until later on.

They regularly block up due to too much toilet paper, sanitary items and even nappies being flushed. Young children are often responsible for blocked toilets and drains. They can also flush a roll of toilet paper, a kid’s toy and even the toilet brush. A blocked toilet is very unpleasant and requires immediate action lest the problem worsens and causes flooding.

Outside drains may become blocked with leaves, dirt and sticks after storms or heavy rain, building up and clogging drains. Common reasons for a blocked drain can be heavy storms. As they are generally not able to negotiate huge volumes of water. Blocked outside drains can cause flooding and damage to homes and businesses.


Common Reasons For A Blocked Drain Could Be Damaged Pipes

Selecting the correct pipes is an integral part of any plumbing job, and so it is important that you have a comprehensive understanding of the pipe work required to do the job. Incorrect installation is not only dangerous but could also damage other parts of your or your neighbours’ property, leading to more expenses down the road. 


Issues with Water Flow are Common Reasons For A Blocked Drain

Water does not tend to flow uphill, as drainage and water flow is all about gravity. Incorrect pipe installation with inadequate falls could contribute to the accumulation of matter and debris that would contribute to a drain blockage. It is important that pipes are installed correctly with gravity in mind to ensure effective water flows. Drains can become blocked for many different reasons, so it is important to take the underlying cause of blocked drains into consideration. Blockages can build up over time and any early signs of a blockage indicates obstructions to the water flow. These include gurgling sounds after you flush a toilet, the water level in your sink or bath draining very slowly, and bad smells from sinks or drains.

A plunger can help clear blockages quickly; however this is a band-aid solution that may not address the underlying causes of the drain blockage. If you have ongoing drainage problems or need to repair or lay drains, ensure to call a professional plumber. Using a professional plumbing service will ensure the job is done properly and will be more cost effective in the long run.
