Finished my Auto Topoff!

[Quinster]

This was how I was going to hook my RO/DI system to my tank via a float switch. The solenoid is in the off (closed) position until the float switch calls for water and opens it...I guess the only way it could fail is if your float switch got stuck in the down position some how...the same idea as the ones used on reactors except this one is all plastic instead of brass. The one question is if you are using this for RO why couldn't you use the brass one if it isn't coming in contact with the salt water?
