My kids got a used RV and on their maiden trip discovered the black tank dump plumbing leaks. Appears to have one or more cracks in the plumbing from the tank to the dump valve. They tried to patch ...

They can do it any number of ways. Mine has the valve right at the tank. On thing to consider is the use of a fernco coupling (google it). If he can cut right before the leak at the end of an elbow and use a fernco to attach to the new piece he should be fine.
Thanks - will look into that. My rig also has cable pull dump valves right at the tanks. I was thinking about suggesting that improvement for him, as well as combining black and grey plumbing into 1 dump valve and connector - his rig has separate dump hose connectors and separate dump valves for black and grey tanks, with the generator installed between them.
For simplicity of repairs, I think we're going to stick with just replacing the leaking parts.
Plumbing the two dump hose connectors together is fine but you want to keep separate valves. Otherwise you essentially only have one big combined tank. Better separate so he can drain black and then flush the hose with grey.
