I live in the country on a well. I had a company come out and give me an estimate for a under sink RO system for $400.00 Think its a good deal ? It a clearwater system.

The $400.00 price is installed

$400 including the install?

Depending on the system, that sounds right in the ballpark.

Do you have a link to their specific system?

You can buy under the sink systems at Home Depot for under $200 but it may require a bit of work on your part to do the plumbing work for the runoff and tapping screw for the feed line.

Just make sure that you can easily purchase filters and for a reasonable price. The filters can get very expensive depending on the brand and how crummy your water is.

:thumbsup:

The systems for undercounter typically will run anywhere from about $150-$400 (the most expensive I've seen 'em).

Depending on how handy you are, like vi_edit said it could be a real labor putting the system in.

The filters issue was a great point also.

Non-RO come very close in performance...many state they are really the same.

RO wastes a lot of water and is also limited by the tank size. Make sure you are buying enough 'water' in your setup.

I am going to go three filter for my setup probably and skip RO. I can buy GE at cost pretty much through my company (a top 10 homebuilder)...we used to have whirlpool as a vendor I preferred their line up on many things.

One thing that stinks is I want a 21/22 cu ft narrow width (29") fridge and GE doesn't make one yet.

I was looking for water filtration because I didn't want to drink stright from the tap (chlorine, lead etc). And I kept reading all over about how reverse Osmosis is bad. And shoudn't be used. Do a google search and you'll find tons of info on it.



"There are multi-stage units, distillers, purifiers and reverse osmosis water systems. Research shows that multi-stage water filters are ideal, but people continue to buy RO systems as they are unaware of the drawbacks.

As stated before, reverse osmosis water systems strip water of its natural minerals. When consumed, this water can cause negative things to happen to our bodies. First of all, water that lacks minerals is more acidic. Therefore, our body will pull minerals from other areas of our body, such as our teeth and bones to neutralize this abundance of acid. The second downfall of drinking this water is that this overabundance of acid increases our risks of cancer. This is because free radicals increase when our bodies aren?t as alkaline as they should be. These free radicals are what lead to cancer."

You got links backing this up? Preferably some hard evidence, and not an Op piece by Martin Spencer.

I did my own...costed $100 for the filter and tubing( kit) and had to buy about $10 worth of fittings...it was fairly easy

Actually there is a lot on the wastes of Reverse Osmosis out there. I love it when people call others out to prove something. Normally in even a simple report to provide and document sources takes a long time.

How about you google up your own with a simple Reverse Osmosis vs search?

It's really not cut and dry...the biggest thing is a lot of water is wasted with RO and there is not much more filtering happening over a good set of regular filters. Also you have a limited supply of water at any given time.

If you're not going to read the posts on the board, shut your god damn mouth and stop talking.

He's not talking about the waste generated from RO. He's talking about ingesting the water causing serious health risks, including being more prone to cancer.

Not to mention in the exact article he takes that quote from, Martin Spencer is pimping a website to sell other water filtration systems.

Limited water for sure. But it does filter better, there doesn't necessarily have to be any waste, and the "health risks" listed are ridiculous. I'd like to know how this "abundantly acidic" water is somehow much more risky than, say, a stomach full of HCl.

Can't say if this is true or not:

I was told that RO water doesn't exist in nature, &

that it's bad for you because it leaches things you need out of your body.

Here our municipal water supply is drawn off a river & lake that are extensively used

for recreation, full of all the stuff humans "leave" when no one's looking out in the wild.

So I'm all for filtered water too. Only ? is the RO aspect of the filtration.

Of course RO water doesn't exist in nature. Neither do vitamin C tablets. Doesn't mean that either is bad for you.

All fresh water is a hypotonic solution compared to your body, so unless you're drinking seawater (not a good idea), all water "leaches stuff out of your body" until it gets reabsorbed in the large intestine. I suppose RO water is ever so slightly more hypotonic, but the point is, your body can handle it. It's just like claiming that eating crackers "sucks water out of your body" because they're too dry.

Water lost is minimal in an RO system because the membrane has to be clean constantly. For every gallon of filtered water 5-6 gallon of water is wasted, however the cost of water lost is minimal for the average household for the convenience of having your own filtered water ontap.

A car wash is around 120 gallon per wash that would easily keep a person watered with RO filtered water for 20 days.

Under sink counter RO system price could be as low as $138 that can be found on amazon.com.

The things that you want to look out for is the life span of RO membrane & filter replacement before making the purchase. An inexpensive initial cost RO system may not be a wise choice if the replacement filters are expensive & have a short life span.

Wow. That is utter BS. At least the part about acidity and basicity and free radicals and stuff.

Secondly, water without minerals shouldn't affect the pH to any appreciable extent. Carbon dioxide will dissolve into water regardless of trace minerals, and make the pH 5-6 instead of 7. Notice this is about 10,000 times less acidic than a soda, pH 2-3.

The wasted water shouldn't be a big deal because you're only using it for drinking water anyway. And if you use that Costco one you aren't wasting any water..

We have one because of arsenic. $150 dollars for a 10 gallon a day one and 2 hours to install there virtually no plumbing to be done. The longest part was keeping all the hose untangle when I installed

If he has arsenic in his water the only thing that will take it out is an RO. We have a 10 gallon that works great for our family.
