Chesapeake, Virginia doesn’t have the best water. I had bought a brand new Samsung refrigerator and couldn’t even use the water dispenser because I didn’t want to drink the nasty water (even though the refrigerator had a filter).
So, in July (with my father’s help) we decided to get a Reverse Osmosis system and try to hook it to the refrigerator. It was actually quite simple. The refrigerator actually sits adjoining the garage wall. I installed the reverse osmosis system in the garage behind the refrigerator.
I went to Lowe’s and purchased a Whirlpool High Capacity Reverse Osmosis System Water Filter. The whole project cost me under $250 and now I have ultra pure water! The filters need changing about every 6 months or so. This has been a lot better than paying for bottled water.
If you wish to do this install, you will notice that the system comes with a sink faucet. It gets a bit confusing since there is 3 hoses that go to that faucet. The hose that goes to your refrigerator is blue. There is a drain hose that comes out of the Reverse Osmosis Assembly that should just go to any drain. Since I put this unit near our water softener (also installed easily by myself), I used it’s drain line also. I have the drain line go into a one of those condensation pumps used on air conditoners.
Here is a diagram that very closely shows what I did:
Update: The drain line from the RO was changed so it didn’t have pressure. I have it emptying into a tub that has a automatic sump pump. That pumps the bad water away when it fills. Works great.
