ATO question

[ryno212]

do I need both float sensor and level sensor to run the top off like a tunze osmolator? If not, is both a safer way to go ( one for water level the other for a fail safe shut off)? Thanks

I only use the float sensor. When the level drops it activates a socket in the digital power bars where a solenoid is connected. When powered it lets water though. Set the maximum power on time to 2 minutes. It works excellent, the solenoid is about $20

I bought mine from McMaster-Carr
Go to: http://www.mcmaster.com/ and do a search for 7877K2

Or there is always ebay, but make sure it is suitable for RO/DI water, the one above is.
