Drainage systems do not depend on pressure, as supply systems do. Instead, waste matter leaves your house because the drainage pipes all pitch, or angle, downward towards the sewer. Gravity pulls the waste along. The sewer line continues this downward flow to a sewage treatment facility or a septic tank.

How does a house drain work?
Your home’s drainage system uses gravity to pull water through the house and outside to drain. Waste and dirty water is piped through a “Soil Stack” which in turn takes the waste through a main drain, generally located underneath the house. Vents prevent these gases from escaping through the house.
How do drains and sewers work?
Wastewater disposed of via toilets, sinks, showers or baths are channelled into underground foul water drains and sewers. Debris, such as rubbish and grit, is removed from the water, which is held until the solids have separated from the liquids. These solids are then collected and often used as fertiliser.
How does a drain become blocked?
9 Most Common Reasons for Blocked Drains
- Plants and Dirt.
- Grease Build-up.
- Heavy Rain and Storms.
- Broken Pipes.
- Poor Water Flow.
- Bad Pipe Installation.
Do toilet and shower use same drain?
A toilet and shower can share the same drain but they cannot share a waste trap arm for sanitary reasons. Both shower and toilet wastewater go to water treatment facilities, but shower water used to drain outdoors. Below, we will get into why these drains are typically separate.
What is the main drain in a house?
What is a main line? Simply put, your mainline is your sewer line. It’s the line that goes from your house to the city connection or your septic tank. Before leaving your home, all of your drains dump into your mainline.
Are sewers and drains connected?
A drain is a pipe that serves only one building, conveying water and waste water away to a sewer. A lateral drain is a section of drain positioned outside the boundary of a building, connecting with the drains from other buildings to become a sewer.
What is the difference between drain and sewer?
By definition, a drain is a pipe that serves only one building, anything from a house to an office block. All water and wastewater is carried along this pipe into the sewer system.
Where do sewer drains lead to?
If you are not connected to a sewer system, the liquid wastes from your home go into a septic tank, where most of the solids settle out. The water then goes into a leach field, pipes buried in the ground that have holes in the bottom.
What to do if a drain is blocked?
Repairs to sewers If you have any problems with your sewer or lateral drain, for example if it’s blocked, contact your local water company. Your water company has a right to enter your property if it needs to do this in order to inspect or maintain the sewer.
Why are my drains not draining?
1. Attack with boiling water. When hair, grease, soap residue and other debris get stuck in your drain, boiling water may be all your pipes needs to loosen the blockage. It’s the simplest fix, which means it should be your first move when trying to unclog a sink.
What causes outside drains to block?
The usual suspects for blockages in outside drains are leaves, branches, soil, mud, moss, litter and other outdoor debris. As with your inside drains, pouring fat, oil or coffee grounds down the sink does not make for a happy outside drain.
