Very helpful.  Thank you.  I have your book, taking your fundamental course.  I will pay close attention when I get to those sections.

RVs usually have all the greywater plumbed into one drain line exiting the RV. Is your like that? Depending on how much greywater you’re generating, you could install a gravity-flow, branched drain system from the greywater pipe. If you find you’re generating too much water to easily distribute it via gravity, then you could install a separate system from the washing machine so it doesn’t enter the greywater line. This would be a laundry-to-landscape systems.  My book, Greywater, Green Landscape, walks you through the design and install steps for both these types of systems.

Good luck with your project!
