Microline ASO Complete Assembly (ASO) S2029

Item #: ASO
ASO
$19.00

Includes (4) S2009, S2005, S2013, S2011, S2007, S2006, S2010.

Replace this "AIO" kit to fix an issue of a Microline RO unit that continually drains water down the drain & never shuts off - and/or - never turns "On" to make water. 

The ASO is the Automatic Shut Off control for the Microline R.O. system. If the diaphragm fails to seal, the unit will continue to run water down the drain. If the diaphragm fails to "open" the unit will not product water 
 
The ASO senses when your Tank is FULL by the pressure exerted on it.  Note that Too Much Air Pressure in the RO Storage Tank will cause a similar problem. (Tank Pressure should be 8 - 9 psi when the tank is empty of water).
