Why did you pick this product vs others?: Installed this water softener this weekend, replacing a different salt-free ION exchange system that wasn't softening anymore. The picture says it all. The test strip on the right is our very hard, untreated water. The test strip on the left is the same water after being treated. Pretty amazing. Will update if anything changes, but so far the build quality seems really good, the menu is easy to navigate, and the size is perfect for our limited space. My only nitpick is I wish it came with brass fittings. The plastic ones it comes with are pretty heavy duty, and I didn't have any issues with them, but at this price, brass fittings would be nice.

This is an amazing unit, compact but yet powerful in its softening ability. Top it off with amazing customer service, I would highly recommend Nick and his team as well as this softener. We had a glitch initially and when I called the phone was answered immediately and the tech team was able to resolve the issue within minutes. Thank you Ispring!

I just deleted my prior view. I won't go into a whole lot of irrelevant detail, other than to post this update: 1) My household water with the 50KG unit installed decreased water hardness from 10 gpg to less than 1 (almost unmeasurable) gpg. The unit works great! 2) If the unit arrives and is not upright (mine came strapped on crate on it's side), refuse shipment (see the manual). It's possible to put it into service, but you may be struggling to fix the unit to do so. 3) Test your water before and after the unit, using the "soap test", and/or a chemical test like the Hach 5b test, to be certain the unit is actually softening your water, as well as to provide proper gpg input of your hardwater, when you configure the unit's electronics. FORGET the TDS/PPM units advertised on Amazon for hard water testing. TDS and PPM won't tell you how your water had changed. It was accurate (i.e. 170 PPM) for testing the water hardness, but the "after" test said it was now 145PPM. Yet, the GPG dropped from about 10 gpg to less than 1 gpg (i.e. very soft water). 4) Installation: Use ** BOTH ** iSpring's video and the directions when installing. Reason? There are elements included in one that are missed in the other, and vise-versa. It should be easy to install and configure, but it just isn't. There are multiple, confusing steps for starting the initial resin tank wash, and first manual regeneration, that I found ... problematic. Kind of like learning a series of dance steps. There's a "balloon" (i.e. vinyl spacer) that needs to be removed - don't forget that. This 50KG unit required three, 40 lb bags of (Morton) salt pellets to start. (Maybe a fourth would have fit, but 3 bags gets you over 2/3's full.) 5) Installation #2). One question I never saw answered is what sort of supply thread fitting was required to mate your supply pipes to the 3/4" or 1" unit's poly connections. It's NPT. FEMALE NPT (i.e. FPT, FNPT).

We had a 16 year old water softener (major brand) that started having issues and we made several repairs but nothing fixed it. We did not want to spend lots of $$’s to replace. I did some research and we decided to try the iSpring model WCS50KG. For us the installation was fairly easy but we are very mechanical and the plumbing existed from the other softener we had. Getting the settings correct took 2 to 3 weeks. We wanted the same level of soft water (or softer) that we’ve had for 16 years. Everything is working correctly, water may be softer than the prior unit and it’s awesome. The unit comes set at maybe a midway point for water softness. We made adjustments and also set it up as if we have 5 people in the home. It’s been in service for about 5 to 6 weeks and we have had no issues. We also had some questions and reached out to the manufacturer. They were very responsive and helpful. Would definitely recommend this product.

I liked the relative ease of installation except for a blip in the manual that we went over with the service people. Phone was answered on the first ring and no waiting or button pushing to get to a very helpful person. Was not redirected to India. The only complaint i have is that not everyone has 1 inch supply lines, mine are 3/4 inch so I had to go to a store to find some reducers since they do not make hoses with 1 inch to 3/4 inch fittings (extra $32 spent). Would be nice if they offered either 1 inch or 3/4 fittings when ordering.

The unit was delivered on time. The customer technical supports are always available and knowledgeable to answer for any technical issues during installation, commissioning, and operation of the unit. The unit looks well built and made of good quality of materials. The interface panel is easy to navigate during the initial setup. I highly recommend this product.

We ordered this softener to replace the expensive Culligan rental we were using. Not only does it take up FAR less space, but it works very well, and will pay for itself in about 9 months. We've been using this for about one week now and are already noticing a big difference in our showers and how clean our clothes are coming out of the washing machine. I highly recommend this softener.
