I plan on living in the rv full time so I’m hoping to get some insight on converting the black water tank into a secondary grey water tank. This project involves me turning the pre existing bathroom into a wet room using a portable toilet that has its own waste tank. I was then going to use that black water tank as the drainage to the shower in the wet room. My questions are, is this something that can be accomplished? Is it safe to do that? Or should I just bypass the black water tank all together and run a second pipeline to the grey tank? Has anyone done a project like this before? Also if anyone is wondering why I’m not just using the shower area, it’s because I feel like the bathroom is a much bigger space, in creating a wet room. Thank you for all the suggestions and help! I’m new to the rv life so I’m doing my best to make my experiences comfortable, and spacious.
