Automatic top off

I got a normally closed solenoid and plugged it into the ATO. The solenoid opened the house water supply going to the RO filter...and it would top off in the sump until the float valve turned it off. In doing it this way, there's no need for having any type of reservoir. It was 100% automatic and didn't require much work to set up.
 
+2 for the Tunze osmolator 3155. Optical eye. Never failedcon me or any of my buddies. Recently upgraded to a 40 gallon ato reservoir so i had to run it up to my overflow box in my sump. Works flawless, Skimmer level stays perfect = beautiful stinky skimmate, and no flood in my house lol.
 
I have a few 3155's, but since adding a unit from autotopoff.com I see zero reason to spend 200 plus on. 3155. In fact the autotopoff.com unit keeps the water level more accurate than my 3155 does.
