Remove Old Cartridge

What happens here

If your waterless urinal is starting to emit an unpleasant odor, it's likely time to replace the cartridge. Begin by carefully removing the old cartridge from the urinal's drain opening. The video demonstrates using a pair of long needle-nose pliers to grip and pull out the old cartridge components piece by piece. Be prepared for potentially messy or odorous material.

Goal: Extract the existing, potentially fouled, waterless urinal cartridge.
