Here's a pic. I like this unit alot. It is inexpensive and has worked for 7 or 8 years without any problems. No pumps, float valves, or electricity in the water. The clear tube goes in the water. As the water level goes down, changing pressure in the tube closes a diaphram switch opening a solenoid valve. I use a float valve as a secondary safety device so if the valve gets stuck open, the tank doesn't overflow.
Simple and cheap. Unfortunately, I can't find a new one. Anybody know where I can find one?

Big whorls have little whorls, Which feed on their velocity;
And little whorls have lesser whorls, And so on to viscosity
Where can I buy this topoff unit?
