Product Overview

The ZeroWaste Reverse Osmosis System with its patented design wastes no water - other systems waste as much as 12 or more gallons for every 1 Gal. of drinking water produced. This system revolutionized the industry; the patented ZRO - 4 Reverse Osmosis System is the first RO that does not waste water by returning unused water from the system back to the home's hot water supply. Reverse Osmosis reduces particles down to the molecular level. The same process used by major bottled water companies. Reverse Osmosis reduces salts and other impurities, giving you high quality great tasting water.

Customer Questions & Answers

Question for the manufacturer: It doesn't make sense that this product contains a Prop 65 warning...

Question for the manufacturer: It doesn't make sense that this product contains a Prop 65 warning and cannot be sold in California as a result of chemicals thought to cause cancer or reproductive harm. Is the sale restriction on this model a result of the type of carbon in the filter and if so can it be substituted out for a compliant cartridge (such as the coconut shell variety)?
Asked by: NewsView
Prop65 does not mean a product cannot be sold in the State of California, it simply means the product must carry a warning about certain chemicals that may be present in the product. For more information on Watts compliance with California's Prop65, please visit http://www.watts.com/pages/prop65.asp

The RO system we use now takes out a large amount of nitrates, knocking them from 22 ppm to 5 ppm. But, our old system is using WAY too much water now, even when not being used. Does this system knock out nitrates? We know not all RO's do.
Asked by: DesertTrip
Reverse Osmosis does reduce Nitrate, but this system has not been tested or certified for Nitrate reduction.

Zero-Waste Reverse Osmosis Water Filtration System is rated 3.9 out of 5 by 13.
Rated 4 out of 5 by from Great system This system works great. Fairly easy to install. However, for my install I needed to replace a few fittings because I did not use the supplied faucet as I had a fairly new airgap faucet already that mached my other faucet.

Rated 4 out of 5 by from A good little system I bought this unit about a year ago (time for new filters). It has performed great. It was easy to install (the tubes are all color coded). The waste water hooks up to your hot water system. There is a small pump that runs when the water is being filtered. The pump is very quite. I have never had a problem with pressure or running out of water. (We use a lot of RO water in our humidifier.) No broken parts. No leaks. No complaints.

Rated 1 out of 5 by from Worst of Watts Premier! Bought this to replace my 5 stage Watts Premier R/O. The old unit worked fine, but wasted a lot of water. I remodeled my kitchen, and in the process, thought I would replace my old R/O with a new one since it was quite old and needed new filters anyway. I was going to buy the same unit (even though it was slow like all R/O's but decided on the zero waste for enviromental purposes. Boy was I wrong! This unit has less water pressure and produces about 3 glasses worth of water at a time, then runs dry. I am now going to try a single Culligan (US-EZ-1)filter. I will try to update this.

Rated 5 out of 5 by from love this system We are here only for 5 months a year and have had this system for two years and just starting our third year. We are just now replacing the filters as we only use it for 5 months each year. We have never had a problem with the system and would highly recommend it. We like the fact that we do not waste any water with this system thus saving on water. We have never run out of water and we do use quite a lot of water from the system. Makes good tasting ice cubes.

Rated 5 out of 5 by from Save lots of Water. Estimates, depending on the unit, run from three to six-gallons of waste water for every gallon produced in an RO. We have had this Zero-Waste system for five and a half years and let me tell you, compared to our Culligan unit that we had for ovr ten-years we are saving about between eight and ten-gallons of water a day. The only trouble we have had was because the contractor installed the pressure gauge on the co-op water meter and probably used the setting of the unit out of the box. The motor ran on and on and I was sure I would have to replace the motor before long. I finally got off my dead rear end and checked incoming pressure at the meter one day and it was only 50 PSI. I upped to it 65 PSI and everything was better, toilets flushed better, water softener was more efficient, as was the dishwasher and the RO pump ran and was done in a few minutes. With the price of water going up and with it becoming more scarce, this Zero-Waste RO is perfect.

Rated 5 out of 5 by from Save Water for Drought I have this system for 9 years now, the original transformer is still working fine. It has some humming sound when the pump is working, but it is not annoying to me. It is under my sink inside a cabinet. All RO systems are slow, but this one is faster than regular RO system with the help of pump. Regular RO system wastes about 4 gallons of water down the drain for every gallon of filtered water it produces unless you recycle that water. It helps to save plenty of water for California drought if all families use it.
