You should sketch out something on paper.. take a photo of it.. and then post it here .
Originally, I had a plan to put storage barrels like pillars on each side of my combination hydroponics/aquaponics setup.... Then I just started thinking about accidents.
Do you have access to the space under the floor? That will permit you to locate those barrels in a completely different part of the home and pump it over when needed.
Pipe length is cheap... Cable length is cheap... Thankfully water molecules and electrons don't need allot of room for travel...There are lots of spaces you can steal (crawl spaces, attic spaces, duct work).
Having completely rewired and re-plumbed my entire existing home in the past.. I have confidence in my ability to run a few remote wires and a supply line, drain, etc.. neatly and well.. Just something to consider...
