[CAUSE] - ASV (auto shut-off valve) is defective - High pressure inlet water bypassing the rubber diaphragms in the ASV and entering the Permeate (RO) water line. - Water may be bypassing the Brine Seal - (large rubber ring around the outside of the membrane) [SOLUTION] - ReplaceASV auto shut off valve. - Remove and reinstall membrane making sure that the Brine Seal is making contact with the inside of the membrane housing wall. Seal the Brine Seal with Silcone sealant. Clean the inside of the membrane housing wall when the membrane is removed. Examine membrane housing to see if it has warped. A membrane's brine seal will slowly form to the contour of a housing that is warping. So the old membrane might fit while a new membrane will have trouble fitting in a warped housing. Replace a warped membrane housing. [PROBLEM] 
TDS of RO water (permeate) is the same as the incoming feed water. Also high pressure and endless supply from RO faucet.
