- Reverse Osmosis ETZWRETROKIT Zero-Waste Retro Kit:
- The ETZWRETROKIT ZERO-WASTE RETRO KIT converts existing traditional 4 and 5 stage reverse osmosis systems to Zero Waste.
- The ETZWRETROKIT can convert your existing Reverse Osmosis unit into a Zero Waste System by adding a few additional components.
- The ETZWRETROKIT RO Zero Waste retro fit kit redirects the rinse water that normally would go down the drain and pushes it into the hot water side of your home plumbing system.
- The Reverse Osmosis Zero-Waste Kit ETZWRETROKIT puts the rinse water into the hot water side of your plumbing system giving you the ability to still use the water for everyday things such as washing dishes, cleaning and other uses that you use hot water for.
- The converted reverse osmosis system produces high quality drinking water and you have the benefit of using the rinse water for uses that do not require the purity needed for drinking.
- The ETZWRETROKIT Zero-Waste RO Kit conserves water by returning unused water from your RO system back to your home's hot water supply.
- The ETZWRETROKIT Zero-Waste RO Kit helps to increase membrane production and provides for faster filling of your reverse osmosis storage tank.
- The Reverse Osmosis ETZWRETROKIT Zero Waste Retro Kit helps to eliminate noise created by the air-gap faucet.
- The ETZWRETROKIT Reverse Osmosis Kit will adapt to any traditional 4 stage or 5 stage reverse osmosis system. However, it is NOT for use with models WP-5, WP-4V, or Manifold Units.

- ETZWRETROKIT Zero-Waste Reverse Osmosis Kit Instructions:
- Note: Reverse Osmosis unit must be installed a minimum of 25 feet from hot water heater.
- Step 1: Turn off the hot and cold water supply lines to the sink at the angle stop valves. If system is hooked up to an ice maker, close the valve to the ice maker.
- Step 2: Drain tank by opening the Reverse Osmosis faucet.
- Step 3: Disconnect the standard hot water sink faucet supply line and install the included water supply valve to the hot water angle stop. Then reconnect the standard sink faucet supply line to the included water supply valve. If the standard hot water sink faucet supply line does not disconnect from the hot water angle stop, the included hot water supply valve will have to be installed at the hot water sink faucet fitting.
- Step 4: Remove waste water tube on membrane housing.
- Step 5a: If system has an air gap faucet, cut the air gap inlet tube approximately 6” from the faucet connection. This tube will not be reconnected to anything.
- Step 5b: If system has a non air gap faucet, disconnect at drain saddle and use the plug provided to seal opening where the tube was connected with drain saddle.
- Step 6: Attach the short tube of the new flow restrictor assembly on the membrane housing.
- Step 7: Attach the long tube from the flow restrictor assembly to the hot water supply valve.
- Step 8: Remove the inlet water tube going into the membrane filter vessel.
- Step 9: Attach the tube from the solenoid to membrane inlet.
- Step 10: Remove the outlet tube coming from the last prefilter bowl’s lid.
- Step 11: Attach the new tube that is attached to the pump inlet to the outlet of the last prefilter bowl’s lid.
- Step 12: Mount the solenoid and pump in a convenient location. Be sure that the tubes are not kinked.
- Step 13: Locate the outlet of RO water from membrane filter vessel. Cut the tubing at the shut off valve.
- Step 14: Locate the tube going to the tank. Follow it back to automatic shut off switch and cut the tube at the shut off valve.
- Step 15: Insert the tubes from the previous 2 steps into both sides of the pressure switch. The switch has quick disconnect fittings which require the tube to be inserted and pushed firmly into the fitting. To disconnect, push on the plastic ring while pulling the tube.
- Step 16: All electrical connections are color coded for your convenience. Connect the transformer to the wiring harnesses.
- Step 17: Turn on the hot and cold water supply lines (open ice maker valve after tank has filled, if connected to an ice maker.) Check for leaks and tighten fittings as needed.
- Step 18: Plug the transformer into an electrical outlet (not the garbage disposal outlet) and let the unit run for two minutes. Check for leaks and tighten fittings as needed.
- Step 19: Periodically check unit for leaks during the first 5 days of operation.
- Shut down procedure for filter and membrane maintenance is as follows:
- Step 1: Turn off hot and cold water supply lines, (close ice maker valve if it applies).
- Step 2: Unplug the pump from electrical outlet.
- Step 3: Open RO faucet to drain tank, leave faucet open. If unit has a ball valve on tank close the ball valve and tank does not have to be emptied.
- Step 4: Follow normal maintenance procedures found in the original RO manual.
- Step 5: After maintenance is complete, turn on hot and cold water supply.
- Step 6: Plug pump into electrical outlet.
- Step 7: Close RO faucet once water begins to trickle out.
