reverse osmosis filtration system

Dee W
by Dee W
We are looking into purchasing a ROFS and I would prefer one only for the kitchen sink rather than the whole house. In addition, I would like a unit that can be installed either under the sink or in the basement. Does anyone have experience with something like this or ideas that may be helpful?

    I can't help you with details Dee and my hubby's asleep, but we have a double tank system in the basement. I've never been a water drinker, but since we have reverse osmosis I can't get enough. Ours is hooked up to our kitchen sink via an extra little faucet and to our refrigerator. It's the best water ever. I would have thought some of it was to do with our having a well, but a friend in Omaha has a RA system and loves it too. If you don't get help from some of the experts here I'll try and remember to ask my hubby tomorrow.

    @Dee W I put one of these in on one kitchen sink (under the sink), thinking that it would be great to drink pure, healthy water. PS, my kids would not drink it. The water had a 'dead' taste, almost bitter. Since then I've switched back to a normal filter. Be sure to taste the water before you make the purchase.

    I've done a handful of these, mostly four stage units with a storage tank. RO systems use ( or some would say waste) a fair amount of water for what is produced. This can be up to 8 or 10 gallons for every gallon of usable water. A simple filtration system can offer water that tastes just as good with far less waste. RO system are slow to "produce" water so a storage tank is needed...this eats up a lot of the under sink space. http://www.youtube.com/watch?v=qmUvTu0KUIs I am fortunate to live in a city that has awesome water...Rocky Mountain Spring water very close to the Continental divide. If I lived in a location where the water was not so great I would do a simple particle filter with a charcoal polish. http://www.homedepot.com/Kitchen-Water-Dispensers-Filters-Under-Sink/h_d1/N-aqv5Z5yc1v/R-202817739/h_d2/ProductDisplay?catalogId=10053&langId=-1&storeId=10051#.UJ_Z4uTBFJs

    Thank-you everyone and KMS for the links. Yair, I never would have thought to sample the water. Becky, we do not have a well system, but our city water came from a watershed and was great until 3 yrs. ago when our system no longer met EPA standards. Now our water comes from the larger city up north. It smells and tastes bad. We have been buying our water from the water machine at a health food store which they tell me has 13 filters including carbon and charcoal, maybe? The store is closing, which is why we are needing to do something soon.

    @Dee W I have city water and a 4 phase reverse osmosis system that is only used for the refrigerator and drinking water. My city water tastes and probably is bad. The system is installed under the kitchen sink. @KMS Woodworks I wish I had your water but I don't want your weather.
  • A reverse osmosis system is really a great thing, but they do take up quite a bit of room under the sink cabinet. Most have them installed under the kitchen in the basement when needed. Yair S is correct with is comment that the water will taste flat. A good filter installed on the sink tap or a side faucet connected to a good quality high performance filter is really all that you need.

    @Sherrie S We had 14 degrees yesterday when we woke...it did not get much warmer all day. One thing about "ultra pure" water is it is actually bad for you it you drink it. Ultra pure water is an extreme "magnet" for minerals in your body and can reduce your normal balance of electrolytes.

    @KMS Woodworks I wasn't told my water would be ultra pure - just a lot of chemicals would be removed from the city water. Florida does not have the best water for consumption. Wow, 14 degrees - I could freeze to death thinking about it.

    Ultra pure water would never be found in ANY municipal water system. It is just way too expensive to make. We had two types of purified water in the pharmaceutical plant I worked in. Our DI (de-ionzed) water was processed using an RO system the size of a school bus...that DI water was then further processed to produce WFI (water for injection) via a 5 stage still.
