Causes of Blocked Mains Drains
Mains drains can become blocked due to a variety of reasons. Some of the common causes include:
- Build-up of debris – Over time, debris such as leaves, dirt, and sticks can accumulate in the mains drains, leading to blockages.
- Tree roots – Tree roots can grow into the pipes, causing damage and blockages to the mains drains.
- Non-flushable items – Items such as wet wipes, sanitary products, and cotton buds should not be flushed down the toilet as they do not break down easily and can cause blockages.
- Fat, Oil, and Grease can build up in the mains drains over time, causing blockages that prevent water from flowing freely.
Methods to Unblock Mains Drains
Unblocking mains drains requires specialized equipment and expertise. Here are some of the most effective methods:
- High-Pressure Water Jetting – This is one of the most common and effective ways of unblocking mains drains. High-pressure water jetting involves using a high-pressure water jet to blast away any blockages and debris that may be causing the blockage. This method is effective in removing even the most stubborn blockages.
- Drain Rodding – Drain rodding involves using a set of flexible rods to push and pull the blockage out of the mains drains. This method is particularly effective for blockages caused by debris or tree roots.
- CCTV Drain Surveys – In some cases, it may be necessary to conduct a CCTV drain survey to determine the cause of the blockage. A small camera is inserted into the drain to identify the blockage, and the necessary action can be taken to remove it.
Prevention Tips
Preventing blockages in mains drains is essential to avoid costly repairs and inconvenience. Here are some prevention tips:
- Proper Disposal of Waste – Properly disposing of waste is one of the most effective ways to prevent blockages in mains drains. Avoid flushing non-flushable items down the toilet and dispose of waste properly.
- Regular Maintenance – Regular maintenance of the mains drains can help prevent blockages. This involves clearing out any debris that may be accumulating in the pipes.
- Grease Traps – Installing grease traps can help prevent FOG from entering the mains drains. Grease traps trap FOG and prevent it from entering the mains drains.

Blocked mains drains can cause significant inconvenience and damage to properties. It’s important to address any blockages promptly to avoid further damage.
