works fine with an undersink filter system
Installed it with a RO filter system under sink, instead of using the supplied tank by the filter system which had Prop 60 warning but this item doesn't.  However, the pipe coming from the top was leaking- so we went by the instructions of the RO system which said to use TEFLON Tape and do atleast 12 rounds with it before connecting the tubing to the top of the tank. After doing that, no leaks.
