Even if your shower tray is full, you can put it over the drain and within a few pumps the cause of the blockage will be eliminated. When the bellows is above the clog, the supply comes from pressing down on the bellows, forcing trapped air into the plug hole. It's the same method as for the classic pistons, but more air is squeezed out. When finished, just spray on the bleach and rinse it under the tap/shower. If you are washing the sink or tub and there is a spill, block it with a damp cloth before you start running. This prevents air from escaping, making the process faster and easier.
