For the water mixing station itself, I went with 1” sch 80 pvc pipe and a series of ball valves that would allow me to use one pump for everything. I also left both of the ends open incase I needed to add something down the line, or incase the power goes out and I need water. The storage tanks are 65 gallon vertical tanks. Fortunately a place in St. Louis Park had them so I didn’t have to pay for freight shipping.
This was my first time pvc plumbing as my previous tanks have all been AIO nano’s, so it was a learning experience for sure. Overall it was pretty straightforward once I knew all of the fittings I’d need, however figuring those out took some time. After cutting, fitting, and gluing, it passed the leak test on the first try. Success! for the 50ft. hose I purchased an outdoor hose hanger which helps keep it out of the way when not in use.
