Reverse Osmosis System Installation

Preparing

1. Adjustable wrench
2. Drill with appropriate bits
3. Teflon tape
4. Bucket

Step 1: Choose the Location

Select a location under the sink with enough space for the system and storage tank. Ensure there is easy access for maintenance.

1. Determine the best location for the faucet on the countertop or sink. If there’s an existing hole for a soap dispenser or an extra hole for a sprayer, you can use that.
2. If you need to drill a hole, place masking tape on the area and mark the center of the hole. Use a drill with an appropriate bit to create the hole. Remember to start with a smaller bit and gradually increase the size.
3. Apply Teflon tape to the threads of the faucet stem and insert the faucet into the hole. Secure the faucet from underneath using the provided hardware.

Step 2: Connect the System to the Water Supply

1. Turn off the cold water supply valve under the sink.
2. Install the feed water adapter between the cold water supply valve and the flexible hose connected to the sink faucet.
3. Connect the tubing from the reverse osmosis system to the feed water adapter using a compression fitting.

Step 3: Install the Drain Line

1. Locate the sink’s drainpipe and identify a suitable location for the drain saddle.
2. Drill a hole in the drainpipe for the drain line, taking care to avoid any existing connections.
3. Attach the drain saddle to the drainpipe, aligning the hole with the hole you drilled. Secure it with the provided hardware.
4. Connect the tubing from the reverse osmosis system to the drain saddle using a compression fitting.

Step 4: Connect the Storage Tank

1. Wrap Teflon tape around the threads on the storage tank’s valve.
2. Connect the tubing from the reverse osmosis system to the storage tank’s valve using a compression fitting.
3. Place the storage tank in the chosen location under the sink.
4. Remove the protective caps or packaging from the filters and membrane.
5. Install the pre-filters into their designated housings. Install the RO membrane into its housing. Make sure it’s seated properly and tighten the housing cap.

Step 5: Flush the System and Check for Leaks

1. Turn on the cold water supply valve and let the storage tank fill with water.
2. Once the tank is full, open the RO faucet to flush the system. The first few gallons of water may contain some carbon fines from the filters, so don’t use it for drinking.
3. Close the RO faucet and let the tank fill again. Inspect all connections for leaks and tighten any fittings as necessary.
