BAD BAD IDEA! It's not just common sense and I can't recite them but there are strict codes to keep sewage and gray water isolated and handled properly and to protect your health and potable water! Back flow preventers, vacuum breakers, one inch minimum air gaps between any drain and water that even comes from a potable source and on and on, just for starters. Connecting black and gray would turn the entire drain system into a black system and that would be one step closer to contaminating the potable water. Sewage in sinks and showers, so close to the potable water system, not to mention sewage smell every time there was a dry trap. Unimaginable... don't do that to yourself! Craig
Please share these strict codes with us.
Black and Gray are already connected...there is no backflow prevention just a simple blade valve.
Only reason to keep them separate is if you are somewhere that only allows gray water dumping. At one time it was considered acceptable to dump gray water on the ground but not black water. That was many years ago...now it all needs to go into a dump station and I've yet to find one that has separate drains for Black vs Gray. Who cares if it's all a Black water tank?
