I am interested in purchasing this RO/DI unit.
Can somone tell me at the bottom there which of the 2 is the best/easiest to install for the feed devices?
There are 2 different Feed Water Devices:
Regular: 1 x 1/4" Needle Valve
or Option A: 1 x Chrome 3/4" Tee with 1/4" Ball Valve
Buyers can select one of two adaptors, only.
