Sometimes, it's possible that one might forget to close a holding tank valve after dumping, or that it wasn't closed quite all the way, or maybe the valve leaks. Imagine that the default black cap is installed on the sewer pipe, and the RV tanks are then filled with stuff through normal use. It's not pleasant to remove the cap when preparing the next dump session to be splashed with holding tank contents.This Valterra cap is transparent, so if anything IS lurking in the pipe behind the cap, at least you know it before removing the cap. It has a garden hose outlet, so relieving any such backload could be managed at least somewhat easier. The garden hose outlet could potentially be used to offload gray water in places where that is permitted. The handle is very rugged and easy to grip, making cap removal and installation easier. It has 4 bayonet slots to securely grip the sewer pipe outlet.
