Is there a lot of waste water from this system? How many gallons of waste water per gallon of filtered water?

Not at all! The system is super efficient and the quality of the water is amazing!

I called Perfect Water today and I was told the full contact wastes 3-4 gallons of water for every gallon of R.O. water. If you buy the permeate pump. it reduces it to 1-1.5 gallons of waste water. Of the R.O. systems i've looked at on Amazon like the Watts and the iSpring, this is unit is far below the 6 gallon average.

Dear Kimberly, I am not the manufacturer, only a very happy consumer. I have no idea... I actually had no idea ANY reverse osmosis system could represent many gallons of waste water, if this is what you are implying. Should that be the case, then I would immediately revert to drinking mineral water out of those wonderful plastic bottles sold by Dasani, etc...

I'm sure there is some since I have the system connected to a drain line, but it's not something that I've ever noticed. There's no noise and I haven't seen a noticeable increase in my water bill since installing the system. I recently had to drain my pool and refill it. That made my water bill go up about $25 for around 12,000 gallons of additional water for that month. With that said even with waste water from the system it is not going to spike your water bill once you install it. I hope this helps. You might contact the manufacturer for details.

Hello Kimberly, yes, with any reverse osmosis system there is waste water, is usually 100% to the water you purify (3 gallons of purified water to 3 gallons of waste water). However, I do not know if this is the case with this system. This information I have about waste water is as old as the reverse osmosis technology is (about 25 years ago). I suspect the current info is the same but I do not know for sure. Sorry I couldn't be more help.-Pat Holland

I am really sadden by the amount of waste water! My water bill went up $50 a month since using this item! I have a family of 5 and use it for drinking and cooking water. I estimate that we waste about 8 gallons of water a day 30x8=240 gallons of wasted water a month...and that is estimating low. No wonder my water bill has gone up so much. I may have to stop using it. I live in a desert and it's just irresponsible to waste so much water!

I get very little waste water through my system..Just once in a while the holding tank will have a little overflow, but not too often. Overall this is a very efficient system..

It says on the description it's 4:1 - meaning 4 gallons wasted for every gallon cleaned.

The upper portion uses 4 filters all at once. The Berkey web site states that the filter lifetime is 3,000 gallons per filter.

Water always keeps running, but there is no such thing as "system is full". You just need to replace these two filters every 6 months.I had this for last 7-8 years and never had anything related to what you are asking about. Water just always flows through the filters...

It's not measured in time but more like usage. Our well water is around 120 TDS and we filter a lot for cooking, drinking and portable use in stainless bottles. Usually around 5 gallons a day. We usually change filters about every 3 months. Note our water is already very good so this isn't typical. We have a large 2 filter water cooler style housing. That's around 30 gallons per month per filter. Much better than the advertised 15 or 16 gallons.

That depends on the rate of filtered water gallons used and proper use of the filter system. Warm/hot water will ruin the filter if allowed to run through on filtered setting. If one person is using the filter for drinking/cooking purposes at a rate of 1 gallon per day, the 200 gallon filter will last you 200 days. Additionally, if two people are using the filter for drinking/cooking purposes at a rate of 1 gallon each per day, the 200 gallon filter will last 100 days. So, just approximate the number of people using the filter system, multiplied by the amount of filtered water used by each person per day, then divide into 200.

There is no water waste. The carbon filters do not boil, evaporate, or spill water. As water passes through the 5 filters, the sediments and other particles get trapped and the clean water makes it out the other end to be used as filtered drinking water.

They have 3 13,000 gallon ceramic filters so in theory 39,000 gallons. That can be done if you are not just filling it up with dirty water, so what you need to do is pre-filter the water through cheese cloth or a towel or something so that your not clogging up the filters. Then make sure to brush the filters clean once in a while and this will do great for you.

It depends on which size container you have. We have the Burkey Traveler which is a little over a gallon and it only uses one filter at a time, but some of the larger containers use two at a time.

I am not affiliated with the manufacturer, but I believe it is 200 gallons. I use filtered water for the same reasons. I do not trust water out of the faucet.

According to the website the bottom tank for the filtered water is 7 liters (~1.8 gallons) and the top part where you pour the pre-filtered water is 5 liters (~1.3 gallons). The filter is rated to filter 211 gallons, so that's about 114 refills of the 7 liter tank.

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.

We bought our Berkey about a year and a half ago, and we're still using the original filters. We have three kids under four, and we refill our reservoir every two to three days. Conservatively, that means we may have filtered somewhere in the neighborhood of 1000 gallons in a year and a half. If I recall correctly, each filter is capable of filtering up to 3000 gallons, so we should have several years ahead of us just looking at the numbers. However, it's probably a good idea to change the filters regularly. It's been a few months since we did the food coloring test. We've been considering getting new filters for good measure, but our filtered water still tastes fantastic. Just writing this makes me want to chug a few glasses of water.

We use the black filters and I believe it's 3,000 gallons each. They say to multiply the filters times that. So I have two filters. We get 6,000 gallons till need replaced. We also use fluoride filters and I believe those are 1,000 gallons. As far as not removing chlorine that's bogus. It removed bacterias, antibiotics,lead,chlorine etc. that's why it is good for survivalists because u can put swamp water in it to make drinkable.

This is difficult to answer since I don't know how much water has past through the filter. The filter is rated for 15,000 gallons of filtered water. If you know or can estimate how much you have used it then you can judge if it has to be changed.

Those guys pretty much answered your question, basically you need to 'wash' the membrane in the filter so you end up with waste water; some units are worse, I've heard of 4:1. Usually, the faster it produces water, the more waste water it produces (for the same size system). BUT, I have something to add; YOU CAN COLLECT YOUR WASTE WATER, to water your plants or use around the house Its really simple, just replace the supplied 1/4" tubing. (I bought a roll of 1/4" tubing, 50ft, from the irrigation/sprinkler department at the hardware store for cheap.), get a reservoir (I bought a 60gallon garbage can for $25) and replace the waste water line (black hose) with 1/4" tuning ran to the reservoir (garbage can) Its that easy, and you don't waste the water anymore! Be Green!! :r)

the 200 gallon size filter will filter 200 gallons so you have to gauge your family's water usage to predict when you hit 200. I have had my filter for 6 months now and have only filter 116 gallons of water and I only use it for drinking

When your filter is installed it will be connected to the drain under your sink in order to drain the waste water produced from the filtration process. This particular system creates 2 gallons of waste water for every 3 gallons filtered.
