Works great, easy to mod
By DCD
I have had this filter for 6 years and love it. As one reviewer stated "I love water now". I have found a few ways to take this from a really good filter system to an awesome filter system...First, don't use a water softener if you can help it. If not, then at least put this before the softener. Water softeners work by removing calcium ions (scale) from your water and replacing them with sodium ions. They usually add Total Dissolved Solids (TDS) to your water and this makes your filter have to work harder, requiring more frequent filter replacements.Second and probably the most important tip, buy a TDS meter. Don't go by the blinking 6 month indicator light. Chances are your filters will last much longer than 6 months. A TDS meter will tell you for sure. Check your water quality once a month. When your TDS starts to rise, it's time to replace your carbon pre-filter. If it goes back down (will be high at first with a new filter), then great. If not, then replace your carbon post-filter. This will greatly cut down on the cost of replacement filters because you only replace them when needed. More than likely you will not have to replace the reverse osmosis membrane but once every few years. Again, go by the TDS meter to tell you when the filters need replacement. I replace my carbon filters about once every 6-8 months and my reverse osmosis membrane every 2-3 years. Throw the battery away and don't even use the 6 month light...To get your filters to last even longer, install a whole house carbon filter right after your water pressure regulator, before your reverse osmosis system. You will not only save money by replacing just the whole house element every 3 months or so, you will also save your plumbing fixtures by keeping sediment out of the lines. By pre-filtering the water, most of the sediment will be removed before it ever gets to your reverse osmosis (RO) system which will make those more expensive filters last longer. Also, by using a carbon whole house filter and not just a regular sediment filter, you will remove most of the chlorine from your water. This will remove chlorine from your shower water and from the water you use to water your plants. They will thank you!Some people have complained about a gurgling noise. This is caused by sludge build up in the drain line. If you take the black line apart, you will see black sludge clogging the line. This causes turbulence, i.e. noise. For maintenance, put a dropper full of bleach in the air break located on the side of the faucet. You can clean the sludge away from the line and inside the key hole shaped air break with a q-tip.If your want more water output, buy a second air diaphragm tank. I have a 44 gallon tank that I hooked up by cutting the yellow hose that goes to the existing tank, putting in a tee fitting and running a second hose to my 44 gallon tank. You can have virtually unlimited filtered water for cooking, ice makers, home brewing beer, hooking up to an aquarium auto-top off system, etc. This filter system is rated to produce about 14 gallons of water a day, if you need more you can always buy another one and hook them up in series. Just add more diaphragm storage tanks as needed. If you add more tanks to the system, be sure you sanitize them. Place a couple of drops of bleach in the tank before you hook it up. Allow it to fill completely with water (overnight or however long it takes). Then, empty it completely through the faucet before using it. Maintenance on the tank(s) requires that you periodically check the air pressure. Pressure should be between 5-7 psi with 6 psi being the target. This system only pressurizes to about 30 psi and so you will have to bleed off some air from any new tanks you install. Most are pressurized from the factory to 30 psi and you will have to bleed it down to 6 psi to get full capacity from them.Now if you want pristine water that will be cleaner than any bottled water you can buy, add a de-ionizing filter. On the side of the RO system, there is a blue outlet line. This is your reverse osmosis filtered water that goes up to the faucet... Cut this line and hook it into a de-ionizing (DI) cartridge. I have a dual chambered system on mine. One end of the cut blue line will go into the DI filter and the other end of the blue line goes into the other end of the DI filter. Now all the RO water will flow into a DI filter resin which will strip out all total dissolved solids leaving you with ultra purified, pristine water. This is a must if you want to use this water for an aquarium. This has practically eliminated my water changes, but that's a different discussion... To make DI filter change out easy, be sure to install a cutoff valve before the DI filter so that you can shut off water from the RO system. You can also shut off water without a shutoff valve if you simply unscrew the post carbon filter on your RO system. You will spill a few drops but it's not that big of a dealOn my system, I bought a permanently installed TDS meter. It has two probes, one for water going in, and water going out. I hooked the probes up to the water flow before and after the DI filter by using a Tee fitting with the probe inserted in the water stream. The "in" probe reads water quality before the DI filter, but after the RO system. I use this to monitor the performance of the RO system. I usually maintain 1-3ppm of total dissolved solids coming out of my RO system. If this number climbs, then I know it's time to replace a carbon filter or two... I use the "out" probe to monitor the DI filter. It has a replaceable resin and when I notice any rise in TDS coming out of the DI filter, I will replace the resin. It's just a grain like sand that you dump in the cartridge. Simple to replace. On my system I always get 0ppm of TDS which is about as clean as you can get. MUCH cleaner than any bottled water you will find. It rivals distilled in terms of quality. My DI resin lasts me about 3-4 years. This is with about 4-5 gallons of use per day.If you do all of these things, you will have a very high quality system that is both easy to maintain and low cost. It's nice having RO/DI filtered water on tap for my fish tank and it makes drinking water taste good again!For clarity here is a flow diagram: Whole house carbon filter-> RO carbon pre-filter-> RO membrane-> storage tank(s)-> RO carbon post-filter-> TDS "in" probe-> DI filter resin-> TDS "out" probe-> faucet. You can tee the line off the faucet and hook it up to your refrigerator's ice maker, aquarium auto top off system, etc.

RO Unit for an aquarium hobbyist!
By Tim
Ok...so I'm not the person that's concerned about taste. In fact...most of you reading this don't care about why Reverse osmosis filtering is important for an aquarium....but let me begin on the basics.1. Yes it wastes somewhere between 4-5 gallons for every 1 gallon it filters.2. It does take up under the sink space...if your not at all good with plumbing and don't hire a professional.3. The filters run about 100$ for a full set - 1 pre-filter, 1 post-filter, and 1 Reverse Osmosis filter. Note: they say you will need to replace every 6 months...If you have hard water and can smell it from the tap, you will likely have to change the filter more often. If you have relatively good clean water the filter could last a year.4. WHY I USE IT: The option of getting a Reverse Osmosis unit not only softens the water, but removes 99.5% of the bad chemicals in your tap. Chlorine, Chloramine, Flouride...etc. I have special fish that need clean soft water - this is the best way to get it.Now - I tried the Home Depot GE version (same price) and let me tell you....it was the shoddiest, cheap, and in the end worthless unit. I took it back after the tank nut cracked while it was pressurizing...only to find out it was also missing a 2 important seals. I returned it and headed to Lowes...Whirlpool Reverse Osmosis Filtration System WHER25Pros :Easy to install (if your not too concerned about how it looks)Highest quality parts than any other competitors in the same price range.Fairly quietSaves money in the long run (for me it paid for itself in a month...but then I use it for large aquariums)Cons :If your not handy putting things together, you'll need a plumber - but you can then have all the equipment setup in your basement or garage out of the way.It does waste 4-5 gallons per 1 gallon of drinking water, but once it fills up the attached tank it stops the process.If you absolutely need to get an RO unit at a budget price, this is the unit you want to buy. I never considered 'whirlpool' a quality product over 'GE', but this is one very large exception to that rule. If you have a larger budget, you might consider some of the large setups - they are more efficient over time and a bit more convenient if you need more that 2.5 gallons at a time.

By EB
In the literature the RO membrane does not need to be changed every 6 months, just the pre and post filter. The RO membrane will let you know when it is time by decreased production or pressure. They indicate "The membrane should be replaced after a decrease in water pressure or quality."Have had mine for 5 years and only changed membrane once. I'm connected to city water and move the post filter to the pre spot and put on a new post filter about every 6 months or so. The pre filter needs to remove big items, the RO membrane removes the disolved solids and the post filter removes the odor. If you have lots of smell to your water, like with some wells, might make sense to change both every time.
