Blocked and overflowing drains in Halifax

A blocked drain can show up as an overflowing outside drain, a blocked gully, slow sink, toilet that will not clear, unpleasant smell or wastewater rising where it should be draining away. The right response depends on whether the problem is local to one fixture or affecting more of the drainage system.

Common signs of a drainage blockage

Watch for water draining slowly, gurgling, water levels rising after another fixture is used, unpleasant drain smells, outside gullies holding water, or wastewater appearing at a manhole or drain. If several fixtures are affected at once, the obstruction may be further along the drainage run.

Blocked outside drains, gullies and sewers

Outside blockages can involve leaves and debris, grease or waste, roots, scale or a defect in the pipe. If sewage or wastewater is overflowing, reduce water use inside the property and keep people and pets away from contaminated water. If neighbouring properties are affected too, the issue may involve a shared or public sewer.

Blocked sinks and toilets

A single slow or blocked sink may be a local waste-pipe problem, while several slow fixtures can indicate a wider blockage. Repeated flushing of a toilet that is already backing up can make an overflow worse. Avoid adding more water until the route is clear.

When a drain keeps blocking

A blockage that returns after being cleared deserves investigation. Roots, damaged or displaced joints, scale or another structural problem may be restricting the pipe. A CCTV drain survey can help identify the cause rather than repeatedly treating the symptom.

How blocked drains may be cleared

Depending on access and the obstruction, a drainage provider may use rods or high-pressure drain jetting. If damaged pipework is found, see drain repairs in Halifax.
