Reverse Osmosis Water Filter a giant waste?

Hello!

I'm on my second one of these systems, the manual calls it a PNRV12ZBL.

The reason I'm on my second one is that I noticed water running from the "product" water faucet to the drain, constantly. I assumed this was due to a faulty system, so this one was returned for credit, and I was given another from a family member. This one does the exact same thing.

I would still assume this to be faulty equipment, however, there is a drain line FROM the faucet itself. If this wasn't a design "feature", there shouldn't be one, except maybe from a bypass valve to the drain. On top of that, under troubleshooting in the manual, it says that hearing water running from the unit to the drain is normal.

I calculated the amount of water the system uses (10 minutes of collection from the drain line into a measured container) and it came out to over 1000 gallons a month down the drain!

At the point I discovered that, I was sickened. That is a LOT of water being wasted for no reason, and there is nothing in the manual I can find to even clue you into this. I'm surprised this product was allowed to hit the market.

Does anyone have any insight or other experience with this system that could shed some light on what is going on, if abnormal?

Thanks!

Old post but later is better than never I always figure haha.

That's how reverse osmosis works. Most setups drain about 5 times the amount of water they filter from what I can tell. For drinking water etc that is not a terrible amount I suppose, but if you're going to r/o your whole house's water that is going to use a lot of water!

I think r/o setups were originally developed by the navy to make sea water drinkable. Waste water wasn't an issue since it just went back into the ocean.

take a look at my new RO system, much less water waste

Absolutely unique and one of a kind the new Next-RO Point-of-Use Pure Drinking Water System has lived up to the substantial product claims at NEXT-RO.com. I own a NEXT-RO Engine which I use for product demonstrations at our health and wellness store.
I have been impressed with the design and construction of the injection molded manifold which eliminates the tubing and fittings between filter housings in traditional reverse osmosis water system designs. Next-RO meets it's claim of refilling the 1 1/2 gallon reservoir ball with pure RO (reverse osmosis) water in about 35 minutes. Mine finishes filling in about 36 minutes each time after I empty it completely.
Most traditional household RO systems run refilling for about 4-6 hours against a steel storage tank's back pressure to produce 1/1/2 gallons of RO water. The zero-back pressure design improvement is in the profound and novel Next-RO Engine- the automatic back flushing valve. The bulky steel water storage pressure tank is no longer required and as a result refill times are much, much shorter with Next-RO.
The Next-RO Engine sits on the counter top or under the sink and can be connected directly to coffeemakers and other appliances and may still be used as a direct fill faucet. Coffee, tea, herbal blends, ice cubes are all noticeably better when prepared with pure water from my Next-RO Engine.
The term "Engine", from the NEXT-RO logo, I believe, refers to the special automatic back flushing valve that allows the magic to happen in this unique design without using a pressure tank or electric pump. The control valve opens and fills the storage vessel with purified water that has gone through a carbon pre-filter, an RO membrane and another special carbon post-filter.

Once filled, and this is the best part of all, the control valve reverses automatically and back flushes some pure RO water through the three quick-change filters, thus the Next-RO filters and membrane sit in pure RO water 24/7. Old style reverse osmosis drinking water systems, by design, have their filters and RO membranes sitting in raw feed water 24/7, day in day out, and do not back flush. Whatever is in the feed water will diffuse over time into the filters and RO membrane. This situation contributes to shorter filter lifetimes and impacts overall system effectiveness.
With regards to performance, the water produced by my new Next-RO Engine tastes great and is crystal clear of course. I did test for dissolved solids removal by using a simple TDS (Total Dissolved Solids) meter. My household water test indicated 350 ppm of TDS (Total Dissolved Solids) and my new NEXT-RO system brought that down to 17 ppm. I felt that was pretty good and besides it makes such glass clear ice cubes and superior herbal teas that I shall not miss going to the store for bottled water.

And, as for the folks who proclaim loudly that drinking water without minerals is bad for you, they may want to stop and consider a little thing called RAIN. People have been collecting and drinking rain water for centuries. I believe that if you are counting on your water for your daily minerals and not your diet, that there are better approaches to consider. If you are looking for the best contaminant free drinking water Next-RO is a solid find. Reverse Osmosis water is in most plastic bottled water sold in stores. NEXT-RO gives you complete control of your drinking water without having to buy expensive bottled water. NEXT-RO The Future of Un-bottled Water is an apt and fitting tag line for this breakthrough water purifier system.
