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.

Can it be used in a travel trailer?

We are living in a 30 foot travel trailer and would like to put an RO system in the trailer so we do not have to buy water from the store, we thought the zero waste was a great way for us to go.
Asked by: Jan
Yes, but there is really no need to. You could simply plumb the waste line of a conventional RO system back to your fresh water tank, thereby achieving zero waste without extra equipment.

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 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.

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 Very nice RO system We bought this system three years ago and it runs great. We use it for cooking and drinking all day long and its pressure is very good and constant. The only down side is that I couldn't find replacement filters in the local stores not even in Home Depot where we purchased it. However, I was able to order the filters from the company's website for very reasonable price ($13 per set).

Rated 5 out of 5 by from ALL. THE GOOD, NONE OF THE BAD I replaced an older 4 stage unit because of the water savings. It performs as advertized. It is important to be sure that requirements such as hot water pipe length and water pressure are met. Water that normally would be wasted is stored in the hot water supply pipe. The water in a hot water pipe usually goes down the drain while waiting for hot water at the tap or the cold water faucet would have been used used. If the supply is too short it won't hold enough RO waste and if water pressure is too high the pump may have to work too hard to push the waste up the pipe. This system easily fills my 2 gal. pitcher without fading to a drizzle like my old unit did and the water tastes as pure even though it has less filters. The pump turns on after about a cup of water. I can't hear it unless the cabinet door is open and the house is silent. I researched the unit on line but bought it at Home Depot because it was available locally. It has T-valve adapters that fit at the hot and cold faucet connections so you don't have to pierce any pipes. This is a big improvement over older systems that used self tapping valves that eventually leaked. I've had it for almost a year now and disagree with statements by some that you would be washing your hands in contaminated water (when the water gets warm it's from the water heater so the waste water is down the drain) or that the pump is noisy (my refrigerator is louder). This system is the answer to RO.
