Drain pipe from black and grey

[Marv & Jean]

Bob:

The rubber coupling in the drain system is there to give you some
room to remove the valves from the coach. There is probably only an
inch or two space between the ends of the abs pipes but having the
rubber coupling in the line lets you get the entire valve assembly
out. Hope you have having fun in Texas. About 55 and sunny in Ocean
Shores.
