Once SW is mixed, I have matching pumps and the valves are sent to remove old water from the overflow directly to the kitchen sink and add new water to the sump from the SW drum. The whole process takes about 15 miuntes. I have also recently added (not pictured) a secondary valve off the new SW sump fill line to be able to easily get water for my QT when needed.

Where did you get these? Thks
