Abstract
An indicator that the cartridge is draining slowly is placed on top of the cartridge. When slow draining causes urine to pool on top of the cartridge, liquid enters a float housing, causing an indicator to change color. The indicator is visible through a lens in a diverter. The indicator may be a disk that undergoes a chemical reaction to change color or a float that flips over to reveal a side having a different color. When the cartridge is operating properly, the float displays a first color. Flipping of the float reveals a second color to the observer. A color change indicates, such as by signaling, that the cartridge needs to be replaced.
