Basin Waste Guide
Different Styles Of Basin Waste
There are five different styles of basin waste kit - chain waste, click-clack, captive, free flowing and pop-up.
- Chain Waste - this is the traditional chain and plug which is usually used with traditional style basins.
- Click-Clack Waste - also called a sprung plug, you push the plug in with your finger and it clicks shut, to open it you push it again and it clicks open.
- Captive or Flip Waste - the captive or flip waste sits neatly in the plug hole with its top flush with the sink, it is cleverly designed to pivot when pushed on one side (any side!) and by doing so it opens and then can be pushed back and closed, a very simple and neat solution.
- Free Flowing Waste - this kind of waste can't be closed, it sits over the plug hole, just proud of the bottom of the basin. These are used with basins that have no overflow and that are intended to be used only with flowing tap water. If you are fitting a basin without an overflow in a commercial setting (e.g. Hotel) them you would definitely want to use one of these.
- Pop Up Waste - These usually come with a tap and are operated by a control which is usually at the back of the tap.
Slotted and Unslotted Basin Wastes
Each of these wastes is available in two different versions Slotted and Unslotted. If your basin has an overflow you need a slotted basin waste, if it does not have an overflow you need an unslotted overflow. If you fit the wrong kind of waste kit in this regard then your waste may leak water onto your floor or your overflow may not work or both.
You don't need to know this, so don't worry if its more than you want to know, but the reason you need the correct waste is that a basin with an overflow will have a channel in the pottery casting that takes water from the overflow hole and delivers it to an opening in the inside edge of the plug hole. A slotted waste has a slot in the threaded metal tube that goes through the plug hole and this slot marries up with the overflow opening in the edge of the plug hole allowing water that goes though the overflow and into the overflow channel in the body of the basin to get out through the plug hole.
