Tap water is the cheapest and most accessible drinking water we have available to us today. However, due to poor quality water sources and treatment techniques, tap water might not be your first choice for drinking. Your reasons might range from bad taste to the fear of chemicals like chlorine, fluoride, or contaminants like lead.
Whatever the case, a Reverse Osmosis Water Filtration System can be your answer to clean, pure drinking water! This video will focus on the installation of a home under-sink RO system.

You'll see the following steps in detail:
1. If there's no available 1-3/8" hole, mark out a suitable location on the counter-top and cut the hole using a 1-3/8" hole saw. If your counter-top is a hard stone like granite, quartz, or concrete, you'll need a diamond tip hole saw.
2. Assemble and install the faucet into the 1-3/8" hole.
3. Connect white 1/4" tubing to under-faucet.
4. Connect the feed water adapter to your cold water line.
5. Drill 1/4" hole through 1-wall of a vertical section of your PVC drain pipe.
6. Install the included drain saddle with the red 1/4" tubing inserted .6" into the drain pipe.
7. Place the system housing under the sink.
8. Attach the tubing and power cord to the back of the system housing.
9. Insert the filters into their respective locations.
10. Open the valve on the feed water adapter to allow water into the system.
11. Plug the system into an AC outlet (yes you need AC power under the sink).
12. Follow directions to flush the system.
