Looking good!
I SOOOOOO recommend running a line upstairs. I use that line in both directions. The return pump shoots water down the line and into my sewer waste line. Flip some valves. Hit a remote power supply that drives a pond pump in my salty barrel for a 40G WC in 20 minutes easy.
A couple of pics of the valve setup that me & my LFS came up with.
Thanks @ScottB ! Do you have a recommendation for a pump to put in the SW reservoir? If I went with a hose/tube I'm guessing I'd be looking at around 35-40 feet, some of it being vertical of course.
Glad to hear your QT is over as well, and no copper power was required
