I will be adding a gray tank to my Caravel
. It will be below the floor. The black tank will be eliminated as I am going to a composting toilet. It can be vented out the existing black tank vent stack.
The question is : can I vent the new gray tank out the vent that the kitchen and bath sinks vent out of? Or do I need to use the vent stack that the black tank uses now?
Any ideas or suggestions are appreciated.
