2021 Coachman Leprechaun 311fs
Do you have a schematic diagram for the plumbing on a 2021 coachman leprechaun 311fs. There is a valve handle behind and above the rear passenger side tire, what is that for??

It is the black tank release valve. Keep it closed while traveling it keeps the weight of the stinky stuff out of the cross pipe so it does break I guess. On the drivers side there is 3 valves one in front is for the washer dryer combo. One on top is black tank the last one is Grey.

Thank you, do you keep it closed until time to dump if you are boondocking? What about at a rv park? Do I keep it closed until time to dump?

Basic rule on the black tank is keep it closed until it is time to dump. Leaving it open will lead to the "brown pyramid of doom".

fyi, washer drains directly out, not to the gray tank. Id recommend running a load and watching it carefully at the beginning. My inline anti siphon was twisted up by installer, water quickly came out on the floor until i fixed it .

We tend to close both valves out of habit until we dump. That way we don't accidentally travel down the road with a full cross pipe.
