Should the bathroom sink in a class a rv be plumbed to the grey or black tank?
Forum Discussion
Wash tank (if you have one) is the same as Gray only no kitchen sink.
If not wash tank (or if it is remote) then gray tank is next choice
Finally some Makers hook it to the black tank, That is NOT something mine did or I would recommend. but that's how some do it.
Reasons:
In many areas WASH tank can be dumped on ground, at least when fresh (not held)
In some (Fewer) areas, so can GRAY
Black must ALWAYS go into a proper hole in the ground (Sewer system or pump out truck/wagon that goes to a hole in the ground)
NOTE: some areas require all 3 go into a proper sanitary sewer, But Well.. The farther you are from black, the more likely to be legal dumping on ground.
