Now for the spaghetti portion of the program. You’ll have color-coded tubes: blue for feed water, red for drain, black for storage tank. Follow the diagram like it’s a treasure map. Push each tube firmly into its fitting until it clicks—if it doesn’t click, it’s not in. No click = future flood.
Connect the drain line to your sink’s drain pipe. You’ll need to use a saddle valve or a clamp-on fitting. Just drill a tiny hole in the drain pipe (if you haven’t already), and secure the tube. I promise, your sink won’t explode—it’s very sturdy, like your grandma’s fruitcake.
Step 6: The Tank Connection
Your storage tank is the waterbank. It stores clean water until you’re thirsty. Connect the black tube from the tank to the system’s tank port. Before hooking it up, inflate the tank to 7–8 psi with a bike pump. If you forget, your water will dribble out like a tired toddler. Nobody wants that.
Hand-tighten the tank valve—don’t use tools or you’ll crack it. That’s a $50 mistake you just avoided. You’re welcome.
