When you extend the slide out there is a foot wide slot underneath the floor where you have access to the pipe and harness of wires. You have room to put your head up and see the duct work and flex drain going into the gray water tank. The swivel allows the pipe to rotate taking away the stress. Also I tie wrapped the bundle of wires to the flex drain keeping the bundle from pressing on the abs pipe shearing it off. Hope this helps.
