Review: 100 plus year old well water - This might be different unscientific take. These pics show my Airsense Cpap and the water by it or in it. Usually because my cpap requires distilled water, my well water here clouds up in one night in the humidifier and the heater pad is solid white. It's been well over a week without cleaning the chamber and look at the water. Still water and not a cloud. My refill glass is also 2 days old and no hardness. That's pretty good results and proof enough when you can go from every day cleaning to every other week or so..Pretty impressive for a 120 plus year old well and a easy to install device put in after my 5 micron sediment membrane. I researched and that was the most optimal for my really old house and well. Love it so far.
Review: Don't believe the nay-sayers, I was skeptical but it worked - 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!

## Features

- HOW IT WORKS: Yarna CWD48 is a Patented alternative water softner for homes that treats water with electric pulses generated within the electronic unit and controlled by a micro-chip! These pulses are transmitted via our Ultra Flat Impulse Bands which breakdown crystals that would otherwise buildup into limescale, which can break appliances.
- WHO BENEFITS FROM YARNA: Our customers report cleaner pipes and faucets, lower costs for descaling and heating, and better overall water quality using our whole house water softener system alternative. Depending on the current condition of your plumbing, it may take up to three months to observe a significant improvement
- EASY INSTALLATION: All you need is access to a minimum of 10" of free pipe space with a maximum pipe diameter of 4". Yarna whole house water descaler is completely DIY with no need for any tools or specialized help. Our whole house water descaler works with any type of piping up to 4" thick
- WHY DESCALING IS BETTER THAN SOFTENING: The Yarna CWD48 water softener descaling system won't eliminate beneficial minerals from water. Additionally, unlike traditional whole house water softeners, Yarna does not require the use of salt and does not allow water to be wasted

## Questions & Answers

**Q: Can this be used with a already installed water softener and if so is it better to be installed before or after the water softener?**
A: I have a salt water softener on my house hot water supply , and a water conditioner on the hot water heater exit into my house which works well.   I have purchased the "Capactive  Water Descaler" to put on to the main water in supply into the house, but have not installed it yet, because of the weather.

**Q: The pulse waves seem to be moving apart as they form. Is it working? I do not see any results yet :(**
A: Thank you for your question. We've made some modifications to the waveform of CWD48. The gaps of the waveform now are bigger compared to the previous one which is thinner and closer to each other.  But to further assess your unit, please send us a photo of your display screen showing the waveform. I'm sorry as well that you haven't seen the results yet. The results of using our device depend on many factors like the condition of your plumbing, how thick and hard the existing limescale deposits you have, the pH level of your water, its components and temperature... etc. And these factors vary per customer that's why some may see the results right away, while others may need a few more months to notice the best results. You just need to give the product enough time to work for you.

**Q: Will my tds & ec meter still show high hard water readings?**
A: It should lower quite a bit.

**Q: Can you insulate the water pipes over the bands ?**
A: Thank you for your question. Yes, you can still insulate your pipe over the coils/flat bands of the YARNA CWD48 Electronic Water Descaler. We only care that the copper bands are wrapped as tightly to the pipe as possible. That ensures that all the energy generated by the Yarna reaches the water and does what it is supposed to do. You can use any type of insulation over the coils, even the type that has aluminum foil on top. Should you have additional questions, please feel free to message us again.

### ⭐ This System Does Not Work!
*by S***E on July 15, 2025*

Why did you pick this product vs others?: At the end of 2019 I moved into my newly remodeled condo. I had heard about these electronic devices where you wrap wires around the incoming water pipe to make the water soft. At the time I thought this was a great idea to enjoy soft water without having to buy salt for a softener. Plus this option was less expensive than buying a complete soft water system. So I spent $350 and bought this unit. I installed it correctly. I used it for several years but hard water marks always built up on both my kitchen sink and bathroom sink. I was constantly having to clean it off. Then one day my shower head started making a singing noise. Then my toilet started doing the same thing. At this point I knew I was in trouble with my plumbing. Hard water buildup was causing this singing noise to come from both appliances. So the bottom line is - this device was doing absolutely nothing to soften my water! I ended up throwing this electronic de-scaler system in the garbage. Then I bought a real soft water system that uses softener salt and I have absolutely loved it! I no longer have hard water marks on both my kitchen sink and bathroom sink. So my advice is do not waste your money by buying this system but buy a real soft water system instead that works!
