Mud blockages in external drains are a common issue in the UK, especially after heavy rainfall or garden work. These blockages can cause slow drainage, pooling water, and potential damage to your property. Fortunately, with the right approach, many mud blockages can be cleared.
Before starting, wear rubber gloves
Always wear gloves, protective eyewear, and waterproof boots. External drains can contain harmful bacteria, so it is important to protect yourself during the process.
Remove the drain cover
Use a screwdriver or lifting tool to remove the drain cover. Set it aside and inspect the chamber for visible signs of blockage. Mud often settles at the bottom, forming a thick sludge that restricts water flow.
Manually remove the mud
Using a trowel or scoop, remove as much of the mud as possible. Place it in a bucket for safe disposal. Take care not to push the mud further down the drain.
Flush the drain
Once the bulk of the mud is cleared, use a garden hose with a strong jet setting or a pressure washer to flush out the remaining debris. Work in a circular motion to dislodge stubborn patches. If the water backs up, pause and remove more mud before continuing. Baking soda, salt and vinegar are popular at-home measures to tackle mild blockages
Use a drain rod
If the blockage is deeper in the pipe, a set of drain rods can help. Carefully feed the rod into the drain, twisting it clockwise to break up the obstruction. Don’t force the rod, as this can damage the pipe or cause the rods to become stuck.
A CCTV drain survey is a professional inspection of drainage systems using specialist cameras inserted into the pipes to identify problems that are hidden underground or behind walls. If you require a CCTV drain survey Wolverhampton, companies such as wilkinson-env.co.uk/drainage-services-cctv-surveys-midlands/cctv-drain-surveys/wolverhampton/ can help.
Disinfect and replace the cover
Once the water is flowing, disinfect the area using bleach to remove harmful bacteria. Rinse thoroughly, then replace the drain cover securely.
