Review: Fixes well water 100% - I’ve been extremely happy with the APEC ROES-PH75 system. Installation was straightforward with clear instructions, and the build quality feels solid and well thought out. The water quality difference was immediate — noticeably cleaner taste, no odors, and much smoother than our previous filtered water. The added alkaline/mineral stage is a big plus. The water doesn’t taste “flat” like some RO systems can, and it’s been great for drinking, coffee, and cooking. Flow rate is excellent, and the tank refills quickly. After testing our water, contaminants dropped dramatically, giving real peace of mind. , this feels like a professional-grade system at a fair price. Would absolutely buy again and recommend to anyone looking for a high-quality under-sink RO system.
Review: Easy to install and great water taste - Up until the pandemic, we had been using a large volume of bottled water every week. Since it has become risky to return to the store every time we are out of water, it seemed logical that a reverse osmosis system would mitigate that risk. Installation of the APEC system was not difficult, and I spread the work out over two afternoons. The first afternoon was spent boring a hole in our granite countertop. I used a Milwaukee 1" diamond hole saw purchased at our local home improvement store. I followed the recommendations found on YouTube for boring granite. I made a circular well around the drill site with plumbers putty to hold cooling water for the hole saw. This worked out well in terms of eliminating all of the granite dust and in keeping the hole saw cool. In keeping with the hole saw directions, the hole was started by boring at a 45 degree angle until the hole saw caught the granite. Then, the hole saw was carefully raised to vertical to complete the boring operation. The 1" hole was barely large enough to accommodate the air gap faucet that I purchased to replace the faucet that was supplied with the APEC RO unit. I would recommend boring a 1 1/4" hole. The faucet that I used was a Kingston Brass Concord Collection KSAG8198DL Reverse Osmosis System Filtration Water Air Gap Faucet. It has a long lasting Ceramic Disk Cartridge. I selected an air gap faucet to protect the APEC RO membrane from a drain backup. This is the same protection provided for dishwashers. Because the RO discharge water has to pass through the faucet air gap, the air gap inlet uses the supplied 1/4" tubing, but the air gap outlet uses 3/8" tubing. I ordered some John Guest 3/8" Food Grade Polyethylene Tubing from APEC. The discharge quick connect drain saddle supplied with the unit is 1/4" and that had to be replaced with a 3/8" drain saddle, also available from APEC. That requires that a 3/8" hole be drilled in the sink drain line. The drain tubing should be cut as short as possible while still providing serviceability. If the drain tubing forms a large loop below the level of the drain saddle, the air gap will not drain properly, and discharge water will leak from the air gap onto the countertop. Please note that this drain line requirement is only true when an air gap faucet is used. If the APEC supplied faucet is used, there will be no air gap and no air gap leak problem will occur. When connecting to the supply needle valve, it is important to remember to slide the compression nut over the supply tubing first, then the sleeve and tubing insert. Don't over-tighten the compression nut on the supply needle valve. All of the items described above can be ordered from desertcart. Installation went smoothly by following the detailed instructions found in the installation manual. After installation and system flush I measured dissolved solids of 19 ppm. I am told that anything under 100 ppm is excellent. With a new the calcium carbonate pH+ filter the water pH measured 9.3 which is alkaline. That's exactly what we were looking for. That pH is the same as is found in premium bottled waters. You would have to pay around $16.00 a gallon for those. The maintenance schedule is clearly defined in the installation manual, and the replacement intervals will depend upon the raw water quality. Whenever installing or replacing the filter elements, disposable gloves should be used in order to prevent the introduction of bacteria into the system. One thing that I did not find in the installation manual was an end-to-end sanitization procedure to be performed when it is time to replace all of the filters at roughly a 1 year interval. For that you will have to look for guidance elsewhere. Bacteria has a tendency to grow on charcoal media and that may be why APEC offers a UV lamp solution on some of their systems. APEC cautions not to inject chlorine into the system to clean it. That will destroy the RO membrane. However, whenever the filters are replaced, the housings should be thoroughly cleaned with soap and water. A few words about water pressure after reinstalling the system at our new home that is on a private well. There are times when the water pressure drops below 40 PSI and the RO system will run continuously for hours at a time. In order to mitigate this problem and to conserve water, we ordered a water driven permeate pump from APEC. APEC maintains that it will work to pressures as low as 30 PSI, and I will revise this review as soon as I have had an opportunity test it. The downside of any RO system is that is discharges more waste water than the amount of pure water it produces. That can increase the amount of water being drained into a septic system if there is one in use. If a water softener precedes the RO system, the salt that the RO system removes will be discharged into the sink drain. That will discharge some amount of salt into the septic tank. In such cases it may be better to discharge the RO system drain line outdoors and into a dry well along with effluent from the water softener. Draining brine into a septic system is never a good idea, and in many locales it is prohibited. One other problem that we experienced during reinstallation was that the needle valve on the water supply inlet side would not shut off. It appeared as though the needle valve had become pitted or corroded during its brief 4 months of use in Florida. It became necessary to replace the needle valve that is only available by buying a complete standard feed adapter. Next time it happens, I will buy a different style of adapter that incorporates a different type of valve such as a ball valve. These are available from other RO system suppliers on desertcart. A few words about radon. Since writing the original review, we have moved to a house that is on a private well. We moved the RO system with us. The water softener that is ahead of the RO system introduces sodium that is very easily removed by the RO system. Our well water also contains dissolved radon gas. The small charcoal filters that form a part of the RO system are not effective for removing radon gas from well water. If there is radon in the water, it should be removed before the the water enters the RO system. Then, the radon will be concentrated in a larger activated charcoal filter at a location far from the kitchen where the RO system is usually installed. Large activated charcoal tanks are available that will provide radon mitigation for the whole house provided that the dissolved radon concentration is less than 5,000 pCi/l - in our case 3,760 pCi/l. For dissolved radon levels greater than 5,000 pCi/l water aeration and outdoor venting is recommended, although these systems can also promote bacterial growth.

## Questions & Answers

**Q: How is RO water compared to bottled water?**
A: Just as good or even better. We use the same technology as other major bottling plants use to filter water. RO systems purify water daily in your home which is fresher and healthier compared to water that has been sitting in plastic bottles.

**Q: How effective is Reverse Osmosis filtration compared to other methods?**
A: RO is the most convenient and effective method of water filtration. It filters water by squeezing water through a semi-permeable membrane, which is equalse to 0.00000004 inch! This is the technology used to make bottled water.

**Q: What is the WQA and what are the benefits of purchasing a certified system?**
A: To receive WQA Gold Seal certification, a RO system must be constructed to meet strict public health standards and pass weeks of rigorous testing for material and parts safety, structural integrity, and contaminant rejection performance.

**Q: What is the size of the product, and if I move, can I remove the system to bring with me?**
A: The dimensions are 17.5"H x 15.5"L x 5.25"W, and the tank is 11"W x 15"H. This system is very easy to uninstall. Just close the water inlet needle shut off, take off the water inlet tubing, and take off the whole system in 5 minutes.

**Q: How often do I need to replace the filters?**
A: The filtration process is optimized to protect the RO membrane, so the prefilters (the 3 filters before the membrane) can last between 6-12 months, and the RO membrane & post-filters can last between 12-24 months depending on incoming water quality.

### ⭐⭐⭐⭐⭐ This water filter system is simply AMAZING! The installation is simple
*by C***F on September 30, 2017*

This water filter system is simply AMAZING! The installation is simple, yet hard. Let me explain. The instructions are clear and the steps are simple, plus there are numerous instruction videos on YouTube you can watch before getting started. Nevertheless, working in the very restricted space under your sink is a real pain in the you know what. However long you think it'll take to install, double it! Here are my tips: Put Teflon tape on EVERYTHING before getting under the sink. Ever try to apply Teflon tape with one hand completely outstretched and bent 90 degrees and you can see the work area with only one eye with only half of you flashlight on it? Yeah, it's as hard as it sounds. The drain saddle has fitted indents to hold the nuts in place. Pop them in beforehand so you wont need to use a wrench to hold them in place while you tighten the screws. Also, use something to poke through the drain saddle and the hole you made in the drain line to keep them lined up. I used a small drill bit, but something like a chopstick would also work. A pen or pencil will be too thick. Make sure you have another person to help you install the faucet. It is impossible to sufficiently tighten the nut under to sink to keep the faucet firmly in place without someone holding the faucet to keep it from spinning. I did attempt to pad a set of vice grips to hold it, but after a few spins they simply slipped off. I didn't want to clamp down the vice grips very tightly for fear of damaging the faucet. So right now my faucet is loose and can spin around, but the system still works just fine. When the wife and kids return from their weekend trip I'll have the helper I need to tighten the faucet correctly. The instructions say to wait 2-3 hours for the storage tank to fill before running it for 5 minutes to empty it. Mine was easily filled within 2 hours. I drained it for 6 minutes then waited another hour and drained it for another 5 just to be sure I flushed out any sediment or carbon from the new filters. The final test was with the taste of the water, which was GREAT! I recently moved to San Antonio , TX and the water here has a very noticeable and unpleasant chlorine smell and taste, even after passing through the activated charcoal filter built into our Whirlpool refrigerator (which prompted us to purchase this RO filter in the first place). When I compared a small glass of water side by side from the frig water dispenser and this RO system the difference was like night & day. I am VERY pleased with the results. Now I want to purchase the refrigerator kit to extend the water from the filter to the refrigerator. Unfortunately my sink is directly opposite the refrigerator in my kitchen and I doubt the water pressure will be sufficient to push the water halfway around the room. However, the results are so good I may just purchase another system and stick it under the cabinet next to the refrigerator.
