Foul Drain

Foul Drains dispose of waste water from sources such as toilets, sinks and dishwashers into a public sewer.

Where this effluent water is mixed with rainwater, as carried by Surface Water Drains, the networks is called a combined system.

At the entry point of a Foul Drain, where it is connected to the appliance or fitting, a 'trap' may be installed to prevent noxious gases or unpleasant smells from rising up. A vent allows for these gases to be safely released, often through the roof.

The Foul Drain directs waste water into an Inspection Chamber, where other outlet pipes meet, including those from other properties.

Foul Drain Maintenance

As with all other components of a properties drainage system, Foul Drains should be regularly checked. If you suspect a blockage, it may be possible to clean manually with protective gear and drainage rods, but if there is any doubt, professional advice should be sought.

The noxious gases emitted by sewers can be exceptionally dangerous. Seeking the advice of trained and accredited tradesmen is strongly recommended.
