Similarly, why do sink drain pipes have holes? One of the main purposes of the side holes is to prevent against a flooding sink. When the water is rushing into the sink and overwhelms the main drain, the holes help drain water that has reached the top of the basin. They are usually significantly smaller than the main drain.
People also ask, how does sink overflow work?
An overflow is a small opening in the sink, and it works by letting air flow into the drain while the sink is full of water so the sink drains water more quickly. Bathroom sink drains are available with and without overflows; check whether your sink has an overflow so you can choose the right type of drain.
How do you fit a drainage channel?
Run your channel at right-angles to the fall of the paving with a fall of 1 in 80. Use a 1 metre-long straightedge and shim of 12.5mm to do this. Dig a depth of 100mm along the edge of your patio and fill it in with concrete. Put the first section of channel on the concrete.
