RO water

Point A: Feed water enters the RO's Stage-1 sediment filter at point A.
ESO: From Stage-1 filter water flows to the ESO (Electric Shut Off) valve.
Point P1: Water from ESO valve enters the Pump at P1.
Point P2: Water exits the pump at P2, flows through Stages 2 & 3 carbon prefilters.
Point B: Exits Stage-3 carbon filter (output port) at point B.
Point D: Enters the membrane at point D (membrane cap).
Point W: Waste water from the membrane exits thru point W, drains off via Black drain line.
Point E: Purified water from the RO membrane exits thru point E.
TSO: Flows up and enters the TSO (Tank Shut Off) valve at T1, and exits at T2.
Points F: From TSO, water flows to point F and G, the T-fitting on Stage-5 filter.
Point G: From point G, water flows onto the storage tank.
Point H: When pure water is dispensed, it leaves the tank via the Yellow line, passes thru the Stage-5 filter and exits at point H, then flows onto the RO dispensing faucet.
