Common external drain blockages

Our engineers have experience in cleaning a variety of potential blockages from external drains. In fact, you can avoid the inconvenience of a blocked external drain with regular cleaning to remove insoluble materials before they build up.

Hard water areas are particularly prone to build up due to the high mineral content. Deposits of the minerals can form and solidify over time, leading to blocked drains.

Though they seem minimal at the time, when grease and fats get rinsed down the sink after cooking, they can settle and harden. Other small bits of food or debris also end up being too heavy to rinse away entirely.

Blockages in external drains can come from the other direction as well – leaves, twigs, silt, stones and other garden debris can find their way in, as can plastic bags and other rubbish.

Our drain unblocking techniques

All of our engineers have a range of mechanical equipment and tools, as well as years of experience, to carry out drain unblocking of any type of blockage.

1. High-pressure drain jetting equipment
These machines, that are installed inside our drainage vans, are capable of breaking up any type of material that’s causing a blockage. The power of this equipment limits its use to secondary drainage pipework, rather than the primary pipework inside a property, where it could cause damage or flooding.

2. Electro-mechanical ‘sani-snakes’
The electric motors in these machines allow our engineers to push a rotating, flexible cable into pipework. Different attachments allow them to push through any type of blockage, including scale and fat deposits. They are portable and are ideal for unblocking internal, primary drainage pipework.

3. Drain rods
The more traditional rods are still a very effective way of unblocking external and secondary pipework. Sections of strong but flexible rod are attached together and pushed by hand into the drain. A range of different attachments can be fitted to the end depending on the blockage that needs to be cleared.

4. CCTV drain surveys
If the location or cause of a blocked drain proves difficult to identify CCTV camera equipment can be used. As well as clearly identifying the blockage this equipment will record any defects in the drainage network that could be causing the blockage. For example, places where tree roots have broken through a fractured drainage pipe.
