Thanks again everyone-I'm getting some great ideas from your thoughts.
I heard that some Keystone FWs did plumb the bathroom sink to drain into the black tank, and did not mention that "feature" to the owners, which caused a few people to scratch their heads trying to figure out what was going on. But one could also see Keystone's thinking in that the black tank should have plenty of water to keep the solids in suspension. But that approach didn't actually flush the toliet with grey water, instead you still need a fresh water flush.
How would I tap the grey water tank? I like Old-Biscuit's thoughts on transferring liquids between tanks. Again, I don't want to simply dump grey water into the black tank, rather I want to also save some fresh water by flushing grey water into the black tank. So if I installed a drain valve on drain line close to end cap and tapped in just before the new drain valve-I could simply pick which grey tank I want to use for flushing-just DON'T PULL THE BLACK TANK VALVE.
I'll probably wait until spring to begin this project but I'll post my progress and give my analysis of this mod. And your thoughts are always welcome.
