Grey Water Tank With Pump

Hey Guys,

New here, and and starting to plan out my first build. I plan to have a full shower with cassette toilet located inside. My question is, has anyone run this system or something similar with the fresh and grey water tanks in the cab vs underneath.

I plan to spend a substantial time in the winter where I don’t want freezing tanks. I understand that fresh water can just have a pump. Can grey water work reversed from the shower drain to tank in the back?

Thanks in advance for any response.


Sure, you could pump your shower drain into the back, but I would suggest a large enough basin to catch all your shower water initially, and then just pump it all in one go.

Ok good to know, I will certainly consider that. Thanks for the response.
