How many gallons of tap water does it use to make a gallon of clean water? Does it waste a lot of water?

Im not exactly sure how many it makes per day but I have a family of 6 using it all the time and we don't run out of filtered water ! Hope this helps!

This unit makes 75 gallons of RO water a day, which means it makes a gallon of water in about 20 minutes (or an 8 ounce glass of water in about 75 seconds). We use RO water for all drinking and cooking (we cook a lot). We have not had any problems with the unit keeping up with us (and our two dogs, which only get RO water).

First, the unit doesn't produce a full gallon. Because of that, you can only fill the tank with about 3/4 gallon. I does shut off automatically by use of a ballast that drops to a certain point in the water. There is always about a 1/2 gallon of water and distilled chemicals in the lower part of the tank. There's a drain valve on the back to get rid of the bottom water every once in a while.

I have always used 2 filters at the time.For two people they usualy last about 70 gallons(36 cents/gallon). It depends on the reading you get on the tester from your tap water. Mine is about 240 ppm.I am thinking of purchasing right now a Berkey filter unit. They are a little more expensive but a set of 2 filters($107) works for about 600 gallons(18 cents/gallon). You also have an option for an extra set of filters to remove arsenic and fluoride. Check out their website at www.bigberkeywaterfilters.com.I hope this will help. Drinking clean water is very important.

I use 2 oz to a gallon of water. My rug cleaner holds 2 gallons so I use 4 oz. I can do a 10 x 13 room with those 2 gallons as long as the carpet is not too dirty.

As Leaser states below, it depends on the quality of water you start with. I use mine at work, so I only run about a gallon a day through it, five days a week. The tap water measures about 180-200 ppm on the meter, and it lasts me about 2 months per filter, around 40-50 gallons, I would estimate.

That will depend on your water pressure, temperature, and contaminant load. At 77 psi, 70F and 250 ppm it will waste about 4 gallons per gallon purified. We offer though our company website a permeate pump upgrade kit that will reduce the actual water waste by up to 80% depending on your conditions. Please be sure to use our kit as it contains everything you will need to make the pump work correctly with the system. It includes the pump, mounting clip, pre-cut tubing, a replacement flow restrictor, and instructions with a schematic. If you do not use our kit you will void your 5 year warranty.

I haven't exactly measured but I would say about 1-2 gallons of water (somewhere in between)

Why would you want too?The filter at best will make 1 gallon of water in 14.4 minutes,that's when it's new.I've had mine for about 7 months, and the time too fill has increased by about 5 minutes per gallon .I use it just for my aquariums. but it still has under a 0.09 ppm,and I make 30 gallons a week.When it reads over 0.25 I'll buy a new one.My guess is that it will last about a year,that will be just under 1600 gallons of filtered water.one more thing this unit has a 2 too 1 ratio,for every 1 gallon of pure water you dump 2 gallons.There are better filters with a 1 too 1 ratio.Also with more gph if you are looking for one under the sink you will want a much faster and more gph no less then 250 gph.Good luck hope this helps.

reverse osmosis units ' dispose' a certain number of gallons of water, and filter out the clean treated water. for every gallon of clean treated water you get, it would have disposed 2 gallons.

It lasted me 2 months making a gallon of distilled water everyday but I used two of them in a gallon. The cleaner the water the longer it lasts. It won't last as long using tap water, I found distilled to be the best and it does a great job. My water always test at 9.5 or higher. Hope that helps.

It makes either 5 or 6 depending on amount of water used. I usually make 5 because I think it tastes better.Friends prefer the 5 also. 6 gallons is a bit "watery."

I don't know as the light has never worked. On the other hand it noticeably slows down when it is time to switch filters. It is about 4-6 months. I don't know how many gallons that is, I just wait. The water tastes much better than the tap water. I have had the system for at least 5 years and have always liked it. I got it to replace the 5 gallon jugs that I was using with a water cooler in my home. Just got too expensive and also too heavy to lift as I got older. Much cheaper doing it this way. You will save a lot of money. Good luck.

16 cups is 1 gallon. And this filters 200 gallons. So 16 x 200 is 3200 cups of water a year. And if you drink 8 cups a day x 365 days a year that is 2920 cups of water every year. And 9 cups a day x 365 days a year is 3285 cups of water every year. So somewhere in between 8 and 9 cups of water every day. Now multiply by number op people in your family and how much you use per day and devide by 3200 and you will see how long it will last.For example 4 people is 3200 / 4 = 800 cups per person. Or if you drink 8 cups a day 2 people will be 1 gallon. So 4 people will be 2 gallons a day. And it lasts 200 gallons. So 200 / 2 = 100 so it will last 100 days.

I have never actually measured the content but I'd say it's about two gallons. The time it takes to filter the water will easily let you make 3 to 5 gallons per day. I bought 6 five gallon water bottles and filled them. I cycle through this oldest first and always have 30 gallons of good water plus whatever is in the filter.

15,000 gallons, or every 16 months, depends really , how much water do you drink a year?
