1. A system for joining a primary sewage line of recreational vehicle to a sewer inlet comprising:
- a rigid pipe, said pipe having first and second sections, said first section for releasable attachment to said primary sewage line, said second section for rotational attachment to said sewer inlet, said second section having a terminal end, an end flange, said end flange positioned on the terminal end of said second section, a first washer, said first washer having top and bottom surfaces, said first washer slidably affixed around said second section with said bottom surface in contact with said end flange, a resilient cylindrically shaped hub band, said cylindrically shaped hub band having an upper end and a lower end, said upper end defining a small axial opening, said lower end defining a large axial opening, said small axial opening aligned with and in fluid communication with said large axial opening, said second section positioned within said small axial opening, said first washer positioned within said large axial opening of said hub band, said hub band extending axially beyond said terminal end of said second section for receiving said sewer inlet therewithin, means to adjustably clamp said hub band to said rigid pipe and to said sewer inlet, said clamping means positioned around said hub band whereby said sewer inlet inlet is receivable within said large axial opening against said bottom surface of said first washer to thereby seal said sewer inlet to said rigid pipe and to allow rotation of said rigid pipe relative to said sewer inlet when said clamping means is loosely adjusted.

8. A system for joining a primary sewage line of a recreational vehicle to a sewer inlet comprising:
- a rigid L-shaped pipe, said L-shaped pipe having first and second sections, said first section for releasable attachment to said primary sewage line, said second section for rotational attachment to said sewer inlet, said second section having a terminal end, an end flange, said end flange positioned on the terminal end of said second section, a first washer, said first washer having top and bottom surfaces, said first washer slidably affixed around said second section with said bottom surface contacting said end flange, said washer extending radially beyond said end flange, a resilient cylindrically shaped hub band, said cylindrically shaped hub band having an upper end and a lower end, said upper end defining a small axial opening, said lower end defining a large axial opening, said small axial opening aligned with and in fluid communication with said large axial opening, said second section positioned within said small axial opening, said first washer positioned within said large axial opening of said hub band, said hub bad extending axially beyond said terminal end of said second section for receiving said sewer inlet therewithin, means to adjustably clamp a said hub band to said rigid pipe and to said sewer inlet, said clamping means positioned around said hub band whereby said sewer inlet is receivable within said large axial opening against said bottom surface of said first washer radially outwardly from said flange to thereby seal said sewer inlet to said rigid L-shaped pipe and to allow rotation of said rigid L-shaped rigid pipe relative to said sewer inlet when said clamping means is loosely adjusted.
