Wastes

 

All countertop and inset basins require a waste plug and we are often asked what the difference is between the three type of waste we offer and which one to choose.

 

Freeflow Waste

The freeflow waste has a domed top which is fixed open.  This allows water to slowly drain out and therefore the basin will never fill up or overflow.    This type of waste is used as an alternative to an overflow and is used on basins that do not have an internal overflow system.  It is used in pubs, hotels and restaurants as a safeguard in case the tap is left running.  It is also popular in the homes of small children and teenagers!

 

What is a basin internal overflow system?

There are internal channels within a basin that has an overflow.  When a basin fills with water and the water reached the point of the overflow, the water will drain down through the overflow and down the internal channels within the basin to the waste hole.

Slotted waste

A slotted waste is used 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.   The waste is closed 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.

 

Non Slotted Waste

A non-slotted basin waste is used on a basin that doesn’t have an overflow system.  The waste is closed 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.

 

Standard or 100mm Waste options

Our slotted and non-slotted wastes come in two sizes – standard 78mm or the longer 100mm.  Which to choose depends entirely on the thickness of the countertop surface the basin is going to be installed on.

The waste is fitted through the sink and through the countertop surface.  It is then screwed and secured underneath the countertop with enough room to attach the bottle trap.

If that surface is thick oak, granite or marble you would be wiser to buy the longer waste to give the plumber plenty of remaining waste thread to attach the bottle trap.
