ABSTRACT:
A transparent pipe trap with means of enhancing the biodegradation of sink effluents in a household sink uses a screen located “downstream” from the trap to deflect valuable items into the trap. The trap is easily drained and easily removed, for convenient retrieval of valuable items, such as rings, which are lost down a sink or other drain. The invention also promotes the biodegradation of sink effluents through time-release biodegradation substances in the cup and/or coated upon the screen.
