Clogged sinks often stem from the buildup of greasy substances like cooking oil and fats, which cling to the pipes' interior after being rinsed down the sink. Over time, this accumulation leads to blockages. To tackle these obstructions in internal sink pipes, two commonly used methods are high-pressure water jetting and drain wire usage.

Blocked showers and baths usually result from a combination of hair, shampoo, and soap residues accumulating within the pipes, particularly at pipe connections. These substances form blockages over time. To resolve these issues within internal bath and shower drainage systems, two common techniques are utilised: high-pressure water jetting and the use of drain wires.

Blocked toilets commonly occur due to an overflow of toilet paper, sanitary products, and sometimes even nappies being flushed down the toilet. Occasionally, blockages can also result from accidental flushing of items like toys or mobile phones. Depending on the location of the drain pipe blockage, external access might be required. This could involve accessing sewer manholes and main sewer pipes, emphasizing the importance of ensuring these drain access points remain accessible. External drains are usually cleared using a combination of high-pressure water jetting and rods.

Obstructions in outdoor drains, situated outside the property, can arise from a variety of sources beyond the usual waste-related blockages mentioned earlier. These may include the buildup of leaves, infiltration by tree roots, and other debris. To tackle these issues in outdoor drains, standard methods typically involve the use of rods and high-pressure water jetting for unblocking and clearing.
