They can be caused by something as minor as hair and soap scum
build-up in sink waste pipes, or as major as tree root infestations or fatty
deposit blockages affecting your entire sewerage system. Blockages in household
pipes need to be cleared promptly, as they stop wastewater from leaving your
property. Sinks or toilets that drain away slowly or make a gurgling sound
could be the first signs of blockage.
Tree roots and dislodgement of drains do not only affect sewer drains
but can also be problematic to your stormwater system, often resulting in
flooding to your home.
