While silica tends to have a less significant effect on scale formation than other minerals, it can act as a binder that makes water spots and scale residue outside the plumbing system difficult to remove. Water known to have heavy loads of dirt and debris may require pre-filtration prior to OneFlow+ OneFlow + Water Filtration System Salt-Free Scale Prevention PLUS Water Filtration OneFlow+ prevents hard water scale buildup in pipes and appliances and removes harmful contaminants for better tasting water. OneFlow+ uses a unique technology called Template Assisted Crystallization (TAC), which attracts and converts dissolved water hardness minerals into microscopic crystals. These crystals flow harmlessly through the plumbing system to the drain, keeping your pipes and appliances free of scale. OneFlow+ is easily installed on a floor or mounted to a wall Virtually maintenance free for up to 3 years Saves money on energy costs and plumbing system repairs Systems using OneFlow+ technology effectively control lime-scale formation inside plumbing systems at hardness levels up to 30 grains per gallon **Testing should be performed to determine proper application where hardness levels exceed 30 grains per gallon Features Improves Appliance Efficiency OneFlow+ scale prevention technology reduces hard water scale

Bought this in Dec of 2020 after I hauled away our old GE water softener (salt). The OneFlow fittings were a bit of a pain to match to our CPVC system, but I got it done. I also agree with another reviewer who said there should be shutoffs on each side of this to make maintenance easier. I put 'em in, and yes, maintenance is easy. =) I've changed the big/outer filter twice (early 22 & now), and the inner once (now). Both times the water between the housing and the big filter was the color of brewed tea (no smell, but still disturbing). However when I pulled up only the inner filter, the water was clear as could be. A few weeks ago we started to see some minor hard-water deposits on the shower heads, so I went ahead and changed both filters (and O-rings). For the inner filter, that's the first time since we put the system in. Now that it's changed, I fully expect another 3 years of not having to worry about hard-water deposits. I can't say it will work for you, but in our book, we've certainly found the system to be worth the money. Read more

Ever since we had this unit professionally installed back in May of 2024; our water pressure has been negatively affected. Our plumber thought that maybe it was the pressure valve; so we replaced it. That didn’t work. So we thought the new valve was defective and replaced it with a new one. Same result. We ended up going through three pressure valves. Guess what? The water pressure still performs poorly. We had fantastic water pressure prior to the system’s installation. So, we then decided to swap the sediment filter out with a new one; thinking that might be the component that was reducing the pressure. The filters are supposed to last one year, but even at the seven month mark it had collected a lot of sediment. So that part of the system works very well. But the pressure is still low, even after replacing the filter. If you shut the filter system off and use the bypass, water pressure is perfect. So it’s definitely the filtration system that is affecting the pressure. I’ve written their customer service department directly on two separate occasions looking for advice to correct the issue; and they still have yet to respond. Hopefully this review will get some attention and positive result for us. Read more

We purchased this product to eliminate a couple of water filtration and non-salt water conditioning. The unit is being used for wholehouse water filtering and water conditioning. Some of the internal parts are plastic and very flimsy. One part that directs water flow internally, broke with the first filter replacement. I have tried several times to obtain a replacement for the part to no avail. I would not purchase this unit for long term solutions to water treatment or filtering. The replacement filters are very expensive, with no solutions availed to you if a flimsy plastic part is broken. The only solution is to buy a new unit. A very expensive proposition. Read more

I installed the filter system this past week. Now it’s wait & see while the unit begins improving the quality of water in our house. I did the installation using a crimp tool, clamps, and a PEX cutter (that came in a kit) I found on Amazon. I locally sourced the Sharkbite clamp fittings including 6 elbows, 2 T’s, 3 ball valves, 2-1” female threaded adapters X ¾” Sharkbite Crimp fittings (I sourced these two parts on Amazon after searching 4 local hardware stores and having 0 luck finding them). I also needed 2-5’ sticks of 3/4” PEX tubing. I ended up with about 3’ of drop or unused pipe. I’m saving it for future use. I needed around 4 hours total time to attach the hanging bracket to the wall with 3” & 1 1/2” wood screws, cut the PEX into the desired lengths, connect the fittings and crimp the clamps. Cutting into the existing water line was the most white knuckle moment because thats the point of no return when you know you’re really committed to the project. Fortunately for me, I was able to tie in the filter system in a section of existing PEX rather than having to cut the copper tubing that comprises the majority of the plumbing pipe in my older home. After I restored the water pressure to the whole house i had NO LEAKS!!! I was ecstatic! Now we have to wait and see if the hard water scale is slowly reduced from pipes, faucets, toilets, and hot H2O tank, as Watts claims it will be. Time will tell! Read more

Don’t let the cost and size fool you- this water conditioner is quite a powerhouse! I have no more limescale/mineral buildup anywhere in my home, my dishes are much cleaner and brighter, water at every point in my home tastes better, and I’ve had no issues at all with this product since I had it professionally installed about a month ago. For reference, I have a 1900 square foot home with 4 bedrooms and 2 full bathrooms. The product meets my needs and I’m very happy with the price point as well. Read more

Read the description, it does work as advertised. “Prevention”. But, in my case I was using it to replace a genuine salt style water softener. If your expectation is that you were going to use this product to replace the salt water softener, you will be disappointed. It does not match the spot reduction of a genuine salt system. Although it is way better than no system. Read more

        "body": "Bought this in Dec of 2020 after I hauled away our old GE water softener (salt). The OneFlow fittings were a bit of a pain to match to our CPVC system, but I got it done. I also agree with another reviewer who said there should be shutoffs on each side of this to make maintenance easier. I put 'em in, and yes, maintenance is easy. =) I've changed the big/outer filter twice (early 22 & now), and the inner once (now). Both times the water between the housing and the big filter was the color of brewed tea (no smell, but still disturbing). However when I pulled up only the inner filter, the water was clear as could be. A few weeks ago we started to see some minor hard-water deposits on the shower heads, so I went ahead and changed both filters (and O-rings). For the inner filter, that's the first time since we put the system in. Now that it's changed, I fully expect another 3 years of not having to worry about hard-water deposits. I can't say it will work for you, but in our book, we've certainly found the system to be worth the money. Read more",

        "body": "Ever since we had this unit professionally installed back in May of 2024; our water pressure has been negatively affected. Our plumber thought that maybe it was the pressure valve; so we replaced it. That didn’t work. So we thought the new valve was defective and replaced it with a new one. Same result. We ended up going through three pressure valves. Guess what? The water pressure still performs poorly. We had fantastic water pressure prior to the system’s installation. So, we then decided to swap the sediment filter out with a new one; thinking that might be the component that was reducing the pressure. The filters are supposed to last one year, but even at the seven month mark it had collected a lot of sediment. So that part of the system works very well. But the pressure is still low, even after replacing the filter. If you shut the filter system off and use the bypass, water pressure is perfect. So it’s definitely the filtration system that is affecting the pressure. I’ve written their customer service department directly on two separate occasions looking for advice to correct the issue; and they still have yet to respond. Hopefully this review will get some attention and positive result for us. Read more",

        "body": "We purchased this product to eliminate a couple of water filtration and non-salt water conditioning. The unit is being used for wholehouse water filtering and water conditioning. Some of the internal parts are plastic and very flimsy. One part that directs water flow internally, broke with the first filter replacement. I have tried several times to obtain a replacement for the part to no avail. I would not purchase this unit for long term solutions to water treatment or filtering. The replacement filters are very expensive, with no solutions availed to you if a flimsy plastic part is broken. The only solution is to buy a new unit. A very expensive proposition. Read more",

        "body": "I installed the filter system this past week. Now it’s wait & see while the unit begins improving the quality of water in our house. I did the installation using a crimp tool, clamps, and a PEX cutter (that came in a kit) I found on Amazon. I locally sourced the Sharkbite clamp fittings including 6 elbows, 2 T’s, 3 ball valves, 2-1” female threaded adapters X ¾” Sharkbite Crimp fittings (I sourced these two parts on Amazon after searching 4 local hardware stores and having 0 luck finding them). I also needed 2-5’ sticks of 3/4” PEX tubing. I ended up with about 3’ of drop or unused pipe. I’m saving it for future use. I needed around 4 hours total time to attach the hanging bracket to the wall with 3” & 1 1/2” wood screws, cut the PEX into the desired lengths, connect the fittings and crimp the clamps. Cutting into the existing water line was the most white knuckle moment because thats the point of no return when you know you’re really committed to the project. Fortunately for me, I was able to tie in the filter system in a section of existing PEX rather than having to cut the copper tubing that comprises the majority of the plumbing pipe in my older home. After I restored the water pressure to the whole house i had NO LEAKS!!! I was ecstatic! Now we have to wait and see if the hard water scale is slowly reduced from pipes, faucets, toilets, and hot H2O tank, as Watts claims it will be. Time will tell! Read more",

    "product": "OneFlow Plus Salt-Free Scale Reduction and Water Filtration Systems use a commercially trusted, physical water treatment technology to keep scale from forming on pipes and reducing appliance life, along with a high-capacity water filter to remove foul tastes, odors, and sediments for better tasting tap water. A single, compact unit with dual cartridges replaces a space-consuming water softening system and water filtration system — using no salt, chemicals, and electricity. OneFlow Plus is an intelligent scale solution and is a great salt-free alternative to water softening (ion exchange) or scale sequestering devices. OneFlow Plus system is certified by the Water Quality Association (WQA) to NSF/ANSI Standard 372 for lead free. The carbon block used in the OFPRFC carbon filter is certified to NSF/ANSI 42. Watts Water Technologies OneFlow Anti Scale Media is certified by the Water Quality Association (WQA) to NSF/ANSI Standard 61.",

While silica tends to have a less significant effect on scale formation than other minerals, it can act as a binder that makes water spots and scale residue outside the plumbing system difficult to remove. Water known to have heavy loads of dirt and debris may require pre-filtration prior to OneFlow+ OneFlow + Water Filtration System Salt-Free Scale Prevention PLUS Water Filtration OneFlow+ prevents hard water scale buildup in pipes and appliances and removes harmful contaminants for better tasting water. OneFlow+ uses a unique technology called Template Assisted Crystallization (TAC), which attracts and converts dissolved water hardness minerals into microscopic crystals. These crystals flow harmlessly through the plumbing system to the drain, keeping your pipes and appliances free of scale. OneFlow+ is easily installed on a floor or mounted to a wall Virtually maintenance free for up to 3 years Saves money on energy costs and plumbing system repairs Systems using OneFlow+ technology effectively control lime-scale formation inside plumbing systems at hardness levels up to 30 grains per gallon **Testing should be performed to determine proper application where hardness levels exceed 30 grains per gallon Features Improves Appliance Efficiency OneFlow+ scale prevention technology reduces hard water scale buildup in pipes to extend the life of appliances and plumbing systems. Great Tasting Water at Every Tap Rated to 20 microns, the integrated high-capacity radial flow carbon block filter reduces chlorine, bad tastes, odors, and other harmful contaminants for great tasting, clean water. Good for the Earth An increasing number of municipalities ban the use of traditional water softeners due to the high salinity of the wastewater. With zero wastewater to drain, OneFlow+ is helping to meet those guidelines.

      "ONEFLOW PLUS SCALE PREVENTION SYSTEM: The Watts Premier OneFlow Plus Salt-Free Scale Prevention and Water Filtration System provides chemical-free scale reduction and protection. It converts hard minerals into soft particles, preventing build up inside pipes and does not add or remove anything from water, allowing useful minerals such as calcium, potassium, and magnesium to remain.",
      "HIGHLY EFFECTIVE: Rated to be the most effective with regard to scale prevention technology, this system includes one scale reduction cartridge good for up to 250,000 gallons or 3 years and one high-capacity 20-Micron carbon block water filter that removes chlorine taste and odor while reducing sediment and is good for up to 50,000 gallons - leading to great-tasting water at every tap in your household.",
      "USER-FRIENDLY DESIGN: This 10\" x 18\" x 10\" (D x H x W) compact system is easily installed to the floor or wall using the included mounting bracket; simply connect the system to the main water supply before the water heater and avoid exposing it to freezing temperatures. Virtually maintenance-free, it also includes a pressure relief valve and multi-function tool for easy cartridge replacements.",
      "ENVIRONMENTALLY FRIENDLY: This system improves efficiency of all water heating devices and downstream plumbing components, improves equipment life, reduces energy consumption, and is a great alternative to standard water softener or other whole house water filter systems. It is environmentally friendly with no electricity or drain required and no waste water.",
      "THE PREMIER DIFFERENCE: Since our founding in 1989, Premier has been dedicated to the design, development, and marketing of high-quality water filtration systems that exceed industry standards. Following our Watts Water Technologies in 2001, our audience and influence have only expanded, solidifying Watts Premier as a trusted leader in the industry."
