Obnoxious plumbing

[nslinkman]

My 1994 had the kitchen sink running into the black water tank. I had
a plumber install a valve under the sink which turns off the water
going to the black tank. Prior to the cut off he put a 'T' and ran one
side through 3/4 pex tubing that i could connect a standard hose to
and run to septic system. We show horses and a lot of times we were at
Fairgrounds where they allowed the grey water run direct on the dirt.
