I have a clean out with an anti-backflow device that I intend on using at some point that I just installed. Depending on where you are and the sanitation agreements you have be aware that most home owners are responsible for there sewer lateral,that is the line that goes from the house to the main line and any clogs are your responsibility. Also in some locals it is illegal for anyone to open/brake into or disturb a sanitation line being a p-trap under the sink or whatever without having the proper license.This personally does would not stop me but I thought I should bring it up. Upon hooking up I would not use anything but a screw in type RV connector such as readily available at Camping world,I would not use a rubber donut (unless there was no possibility of being seen by THE NEIBOURS god forbid) It is concidered hazzardous waste. And if you got any on your wifes champion roses you would be toast.
