Sewer connection rework project.

My sewer connection under the trailer is about 2 feet in. I don't squat well anymore and have to get on my knees to take the cap off and hook up the sewer hose. I'm thinking about cutting and replacing pipe and fittings so I can extend the connection out to the side of the trailer. Here are a couple pics how it sets now, I assume its all glued together and I will probably have to take the deal apart back to the hose clamps by the gate valves.





Any hints or tricks I should know about? I will have to jog around the frame.
