Capacitive Electronic Water Descaler Whole House Solution - No-Salt Softener System, Reduces Limescale Effects and Mineral Buildup, Compatible with Pipes Up to 1 Inch, Model CWD24

BOTTOM LINE:After 3 years... still working strong!Tremendous time-saver and money saver on continually replacing salt weekly to monthly! Customer support is fine also!My first interest in this were the reduction of unnecessary chemicals (salt), the cost and time savings as well as the technology. We have very hard water. The TDS (total dissolved solids) is extremely high. Lots of calcium precipitation with this or the salt-water treatments.Installation location on incoming city water pipe: We installed our Yarna unit before the house water shutoff valve and connected the cord to a standard wall outlet in the basement. We did not use an extension cord. We have unplugged and reinstalled the wrapping coils at least once as we wanted a tighter fit than we initially had.Hot Water Heater to Navien A2: We had an old 60 gallon hot water heater that we replaced with a Navien A2 unit after about 1.5 years of using the Yarna unit. Both are were in our basement installed just below the kitchen. The Navien has a pre-filter so after a year we had it serviced. There were some slivers of calcium buildup in the pre-filter which we removed. There has been no negative impact on the Navien A2 unit so it's working fine.Dishwasher: We have a Bosch dishwasher (15 years old?) that exhibited serious internal calcium (white) buildup on the bottom and sides after we decided to not use the salt-treated softwater approach. Distance from the Yarna unit is about 20' (basement to kitchen). Then we installed the Yarna CWD24 as our city water lines are 1" (CWD30 works for 2" max). After about a year or so, I noticed that the dishwasher deposits were coming off. Additionally, our dishes were looking better with less calcium on them. I eventually purchase the Bosch Dishwasher Quick Descaler (#00312918 - 2 pack). The first time I used it it really (!) cleaned the insides of the dishwasher. About 6 months later, I used it again and the insides are sparkling. So we have a 'new' dishwasher! ;-)Faucets: With such success on the dishwasher, we then went to our faucets (9 in the house - some chrome, some brass). I didn't do the hose connections on the outside. We put CLR in 50% strength on almost all faucets, some with 100% strength and let it soak over night to nearly a week! In all cases we had success. The only issue we still have would be related to where CLR can't get to but these are being taken care of via the Yarna unit's ability to 'soften/eliminate' the calcium buildup in the pipes.Shower heads: Same results with CLR but we were able to remove the shower heads and soak them.Toilets: Inside the water tanks we noticed the buildup and crusting of the calcium which is being neutralized still to this day. We did replace some of the water-closets workings but not all since the calcium made some parts 'hard' (flapper etc.). Some flappers had crust on them that eventually came off - somewhat encouraged by manually wiping these areas and stirring up the calcium deposits from the bottom of the tank to be flushed out. The actual bowl is cleaner also.Shower doors: After years of taking a shower without a softener and then using the Yarna unit we noticed that parts of the shower doors (glass and brass) were losing the calcium deposits (being washed off without any effort on my part). We then started using CLR (1.5" paint brush in a cottage cheese container) and then Kaboom to clean these doors even on cultured marble. I personally like CLR a bit better (used at 50% and Kaboom at 100%) but both work! Both have some 'slickness' to them but it's very minor when you're working in the shower/bath stalls. The shower doors, floor, brass etc all look 90% better but I'm still working on them. Crevices and screw heads take a bit more time.Water taste: Removes salty taste and makes water taste more 'normal'. This may be a personal preference.Cooking: Nothing changed except there's no calcium deposits that occur nor is there any residual 'salt' added.Health: Hard to determine but, with the Yarna unit, we're drinking water without the additives.I would easily rebuy! Actually thought about a 2nd one but I’m told it’s not needed. I don't know how long it will take to fully do our pipes. I don't know of any downsides unless you desire the salt and 'slicker' water.

I was very skeptical this would work but thought I would give it a shot for the ease of installation and the cost. Prior to purchasing I read many reviews stating that these devices scientifically can't work and that they are just a scam. Well, I can confidently say that these nay-sayers were wrong even though they sounded very credible in their reviews.About 2 years ago my wife and I moved into a house on its own well, with all original plumbing since it was built in 1992. The water from the well was tested to be good when we bought the house and the previous owners raved about how good the water tasted, we agreed after drinking it. Although the water tasted great, it definitely had a lot of minerals in that caused a great amount of build up on all the faucets and also in the drains, causing flow issues. Even after we replaced the shower heads and remodeled the kitchen we had white mineral build-up within a month on the new shower heads and faucets, plugging the small spray holes and disrupting the flow.After installing this device I instantly noticed an improvement of the water feeling softer in when showering and washing dishes. It definitely lathers better and leaves your skin feeling less dried out. We have had salt water softeners in the past and it made the water feel very similar.After a few days it cleared out all the newer faucets/shower heads and started to break down the build up on the older original faucets. It even caused a leak in the the drain plumbing under one of the sinks because it broke down the mineral build up in the drain around one of the old seals (I was able to fix it by just taking out the sink drain and trap, cleaning it, and just reinstalling it). Additionally, the dishwasher is not leaving spots anymore and the stainless steel sinks have less spots.After a about week we've noticed all faucets are flowing better and and the old fixtures from 1992 are shedding lots of mineral build up. We can now delay replacing them until we do the bathroom remodels we have planned for the future. The kitchen faucets now spray as they are intended to without any plugged holes.We originally installed this device with the hope of cleaning out the mineral deposits in our plumbing that has built up over the years and hopefully restore some water pressure, and after the results I have already seen I am confident that this will accomplish that. Even though the device does not remove the minerals like a salt softener it definitely descales pipes and improves the quality of the water for our use. DON'T BELIEVE the people that say its a scam or the guys who says he's an electrical engineer and his wife has a few chemistry degrees and call it a pseudoscience scam. The proof is in the results!The only regret I have is not getting the next bigger model that is rated at pipe sizes larger than 1". I assumed my pipe feeding my pressure tank was only 1" but realized it was 1 1/4" when I went to install it. Instead of returning it for the larger one, I just installed it after the pressure tank where the pipe is smaller because I didn't want to spend any more money and I was very skeptical of it working anyway. Unfortunately I won't be able to descale the water going into the pressure tank unless I buy the CWD30, I may end up buying one later on since I am now a believer!Don't be afraid to buy this product this if your goal is to descale your pipes/fixtures, it will do that. Hopefully it will also improve your the quality of your water as it did mine.I typically don't leave reviews like this, but I would have appreciated a review like this when I was researching this product. I hope it can help someone else!
