Auto Shut-Off Valve (ASOV)
$12.00

Automatically turn off the RO system once the system has fully pressurized. 

The ASOV turns off the RO system once the system has fully pressurized. 

Note: There is an IN and an OUT and must be installed exactly how the previous one was. Both red tubings should be inserted on the backside fittings; the blue tubes insert into the front side (the side with the four visible screws) fittings.
