Non-slotted waste plug
Use a non-slotted basin waste on a bathroom sink that doesn’t have an overflow system. Close it by pushing the top of the waste down and water will collect in the basin. To release the water, press the waste top again, and it will pop up, allowing water to flow through.
Slotted waste plug
Use a slotted waste on a basin that has an internal overflow system. The slot holes in the side of this type of waste, when fitted, will match up with the channels in the basin, and then any overflow water will be channelled down the waste and away into the drain. Close this waste by pushing the top of the waste down, and water will collect in the basin. To release the water, press the waste top again, and it will pop up, allowing water to flow through.
Gated waste plug
The gated waste is very popular in pubs, hotels and restaurants as they are used as a safeguard in case the tap is left running and, unlike the free flow, there is no option to adjust the outflow. It is also popular in the homes of small children.
Free-flow waste plug
The free-flow waste has a domed top which is screw-able open to adjust the flow through, but won’t shut. This allows water to slowly drain out, and therefore, the basin will never fill up or overflow. Use this as an alternative to an overflow and or in basins that do not have an internal overflow system.
What is a basin overflow?
The basin overflow a small hole near the top of the basin. It allows water to drain away if the sink becomes too full, preventing flooding should you accidentally leave the tap running.
So remember:
- Basin with overflow: Use a slotted waste
- Basin without an overflow: Use an unslotted waste
