Why sink pipes are curved?
When water stops flowing down the drain, gravity traps water in the curved section. This water serves as a barrier between the open drain of the sink (or shower, bathtub, etc.) and the rest of the sewer system for the house. Sewer gas rises, and the water in the p-trap prevents it from coming back up and out the drain.
Why do drains go down then up?
When water runs down your drain, it flows through the p-trap without obstruction, but when you shut off the water, a small amount of liquid remains in the p-trap. This water forms an air-tight seal against air from further down the pipe from coming up through drain.
Does water sit in Au Bend?
The simple answer is that the water trapped in the U bend acts as a barrier to the foul smells that otherwise rise from the sewer or other drainage pipework. This is why it is an absolute requirement in the building regulations.
What does it mean when water comes back up kitchen sink drain?

How does greywater work in the kitchen sink?
Kitchen Greywater: Water Conservation Straight from the Sink. Reusing water that we already have is a simple and common sense idea, and greywater systems do just that. If regulations in your state allow it, recycling water from the kitchen sink for irrigation can cut down on water waste and save your landscape in times of drought.
Why are kitchen sinks good for water conservation?

Can a sink and washing machine drain line combine?
To start with, know that your sink and washing machine drain lines tend to run congruent to each other. This means they combine at some point on the way to the main sewer line. So, if there is a problem after they combine, it can affect both systems. First, you must pinpoint the problem.
Why does my kitchen sink drain so slowly?
In other situations, the accumulated junk that washes into the drain line builds up, coats the inside of the pipe, and starts to restrict the water flow. When the restriction gets bad enough, water will back up into the building fixtures. A clogged or partially blocked vent pipe will cause the sink to drain slowly, or not at all.
Where does the water come from in a kitchen sink?
Sink Plumbing. The drain would extend horizontally from the P-trap to a tee. The pipe going down from the tee would empty into the sewer, while the pipe going up would extend through the roof to vent the drain. When there are several fixtures close together, however, they usually share drain and vent pipes, and things can get complicated.

Why does water always go down the same way in the sink?
“If you run an experiment in your sink–fill the sink, then pull out the stopper–the water will almost always go down the same way, making you wonder if this is really a random effect. But you will find that the faucet is almost always off center or that there is some other asymmetry in the sink.
