OP, good question, simplifying water changes sure makes it easier to stay on schedule. I don't have a auto water change system, my house floor plan wouldn't allow it. I do have a process that eliminates lifting water.:thumbsup: I screw a hose onto a valve in the sump, roll the hose out the back door and open the valve to drain. Makeup water is mixed in the garage in a brute on a dolly. Roll the can around to the back door and fill up the sump.
