The two spring steel blades on the installation tool fit into the holes or slots around the outside of the slotted, pop up waste. These holes are sometimes referred to as the ‘circumferential slots’ as they go around the circumference of the waste.
The blades hold the waste firmly in place so the lock nut or back nut can be tightened or loosened against it. The pop up waste installation tool helps the user reseal or replace pop up wastes without having to remove the sink, bath, bidet, basin or pedestal.
The pop up installation tool will help you to line up the slots with the overflow and keep them in place as the lock nut is tightened. Basins with fitted overflows will need to be fitted with a slotted waste. However, there are unslotted wastes available for basins without built-in overflows.
