Oh, it's broke apart at both ends. I have since learned it's abs as noted above as well. Yep, seems simple but ain't. The local hardware store couldn't point me to any, not could a local plumbing supplier but I will call Lowe's in a minute. I have at least found some online but have to find the same 90 degree joint where they come together right before the end cap. It broke off at that one end. Sounds like there's some debate about this using glue or just slip fitting. If there's glue involved, I assume I can't just remove the unbroken end from it's elbow and will have to cut and join. My plan at this time is to call the online rv supply place when they open in the morning, send them my pics and let them tell me what I need. I don't know if I can put my pics on here or not but will give it a shot. they're on my phone, not my computer.
