Every sink, washbasin, and urinal discharging water inside a building requires a water trap at the point of connection to the waste pipework. If your basin has an overflow then you need a slotted basin waste and if it doesn't, then you'll require an unslotted waste. How does a slotted basin waste work? The slot's purpose is to allow the water to be drained from the overflow. A basin waste is a channel designed to enable water in your basin to run off safely, regardless of the design of the sink. The basin waste will also allow you to block the pipes of your sink, allowing it to fill up with water.
