We have a house built in 1954 but no lead pipes, although my husband said it's possible we may have some lead soldering somewhere along the way. You can see our lead test in the picture, before and after. If the bottom line is darker than the top line, lead is "undetected." So our water before the test was technically "undetected" but barely. After switching to the reverse osmosis system it was very clearly undetected. The system also brought our total hardness down to 25 ppm from 350 ppm. The reverse osmosis water tested completely negative for pesticides. It brought our ph down from a 10 to an 7.5 We have had this system for 9 months now and have not changed any of the filters so I decided to take the water parameter tests again. Lead was still undetected, although the top line had darkened a bit. (Nothing close to the unfiltered water results though.) Total hardness was still at 25 ppm. Pesticide test came back positive, faint line. We should have changed our first three filters at 6 months per recommendations but my husband thought that was an unnecessary recommendation meant to make the company more money. Would be interesting to see our current water tests had we followed the "rules." We will now change all of them, and start our testing from scratch, and I'll update our tests results here at the 6 month mark. So I would say defintely change the filters as recommended and don't just wing it. Also, we have had no issues with the system leaking as others have claimed. We had a lot of bubbles in the water the first couple days after installation and then they never came back, so if you're worried about that, it doesn't last. Also, my husband had no issues installing the system, but he's a handyman so that's probably why. Last thing I'd like to mention is the water tastes great and very crisp but my husband still prefers the taste of aquafina lol. The system was mainly for me though since I drink literally over a gallon a day, and for cooking purposes. Adjusted for current inflation prices, if my husband and I were still buying the amount of water we were before installation, we would be spending $845.52 a year. So this system paid for itself PLUS all of the replacement filters four months ago. Review: Hooked up to refrigerator only - After reading most of the reviews and the answered questions, I figured that I could just simply install the RO output to my existing ice maker/fridge water supply line and skip installing the supplied RO faucet. I know that the manufacturer still suggests installing the RO faucet, and I could have just used the soap dispenser hole for it, but I thought I would try just using the fridge water dispenser (which we haven't used in years because the water and ice were not good) and this would keep my wife happy by keeping the soap dispenser. And I did not want to drill a new hole in our granite countertop, or let the RO faucet just dangle loose either. So far after about 2 weeks I haven't had any problems and I'm glad I did it this way. I had very little cloudy water initially, like just a couple of gallons, but I emptied the tank anyway. The water tastes very good, and the ice is clean. Prior to this our ice would leave white "floaties" in the glass after melting, which was gross and I don't know what they consisted of either... This approach made installation a lot easier. (1) I just unhooked the old fridge water supply line from the existing ball shutoff valve that I already had in place (close the valve first!), and then hooked that existing fridge supply line to the RO system output (they're the same 1/4" size lines), sending the clean RO water to the fridge dispenser and icemaker. (2) Connected the red input line for RO system feed water into to this existing ball valve (from old fridge water supply connection - no need to install the supplied needle shutoff valve). (3) Ordered a dishwasher drain line adapter (see https://www.desertcart.com/dp/B08YP9VKHZ?psc=1&ref=ppx_yo2_dt_b_product_details) so I avoided installing the supplied saddle drain valve. I just installed the new adapter onto the garbage disposal nipple where the dishwasher drain is attached, and attach both the dishwasher drain and the black waste water line to that new adapter. I would think everyone with a dishwasher should do it this way vs drilling a hole in your drain line. Much easier. The toughest part was removing/reinstalling the garbage disposal so I could put the tank behind it under the kitchen sink, but even that is not difficult. I don't see the need for the supplied RO faucet and now we get chilled RO water from the fridge dispenser (instead of just room temp water straight from the tank), which is wide enough to fill a pitcher or coffee pot. I can always put in a tee and install the faucet at a later date if I wanted, but we'll probably be mostly just filling up glasses and I saw no reason for the RO faucet at this time. I also removed the old fridge water filter and the plastic filter shield/cover (which increases space inside the fridge) and installed a new plastic bypass plug that I ordered for my GE fridge (see https://www.desertcart.com/dp/B07ZSYD3YY?psc=1&ref=ppx_yo2_dt_b_product_details). I suppose you could leave the filter installed if you can't get a plug and it would last longer anyway since it is now filtering the clean RO water, but I like the extra space and the fridge filter is unneeded. Plus, I wonder if it would filter out the added calcium or affect the attributes of the RO water in some way. Probably not, but now I don't have to buy those other fridge filters anymore. ## Features - Supreme quality – designed and engineered with only premium components to ensure high quality filtration and a durable reverse osmosis system for years - This 75 GPD 6-stage system ROES-PH75 is guaranteed to remove up to 99% of impurities such as Chlorine, Taste, Odor, VOCs, as well as harmful Fluoride, Arsenic, Lead, Heavy Metals and 1000 plus impurities.

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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works as intended! *by J***Y on December 29, 2022* We have city water that is sourced from a river, and had been spending a fortune on bottled/gallon water.

Probably not, but now I don't have to buy those other fridge filters anymore. ### ⭐⭐⭐⭐⭐ Easy to install and great water taste *by R***B on May 10, 2020* 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 Amazon. 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 Amazon. 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. ## Frequently Bought Together - APEC Water Systems ROES-PH75 Essence Series Top Tier Alkaline Mineral pH+ 75 GPD 6-Stage Certified Ultra Safe Reverse Osmosis Drinking Water Filter System - 2024 All-New 4 in 1 Tds Meter Digital Water Tester - Accurate and Reliable TDS EC & Temp(Β°C,Β°F) Meter - 0-9990ppm - Professional Testing for Drinking Water, RO/DI System, Aquariums etc - HoneForest Water Quality Tester, Accurate and Reliable, TDS Meter, EC Meter & Temperature Meter 3 in 1, 0-9990ppm, Ideal Water Test Meter for Drinking Water, Aquariums, etc. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.it/products/7626783-apec-water-roes-ph75-6-stage-under-sink-ro-system](https://www.desertcart.it/products/7626783-apec-water-roes-ph75-6-stage-under-sink-ro-system) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-08-28*
