iSpring ED2000 Whole House Water Descaler, Alternative Electronic Salt-Free Hard Water Conditioner, Reduces Limescale Prevent Deposits Build-up, Different from a Water Softener

Installed easily using only zip ties - I didn't use the screws provided.Saw a reduction in sediment at the spigot nearest to the device, within about 1 week of installation. Noticed a reduction in sediment from faucets furthest from the device within a couple weeks of installation. I will still need to add an iron sediment removal device, as recommended, however the water quality has already visibly improved just with the use of this descaler. I recommend this product to others and would install it anywhere the water is hard, as a first step and before adding a water filter or softener.

Update 1 year in: still working like a charm, and now the faucets furthest away from the iSpring have developed some white calcium residue that we have to clean semi-regularly. It’s minimal, but noticeable. This is because they’re so far from the iSpring unit that its effectiveness is diminished, so I take it as further evidence that the unit works exactly as described. I shudder to think of all my faucets looking like that (or likely worse). I might buy a second and install it to mitigate this, but still one VERY happy customer!Original review: I purposely waited 7 months to write this review, to give this iSpring device a fair shot to either work, or…well, not. We built a new home, so new pipes, faucets, appliances, everything. We’re also on a well here, which was new for us to get used to. The well water is really good—basically filtered mineral water, healthy and pure right from the tap with a TDS of around 550. BUT!…that also means in our first month we began to notice white chalky deposits on our taps and shower heads, and some powder on the glasses/silverware after using the dishwasher. We learned it was due to our high TDS well water, and needed a way to protect our new home’s plumbing and appliances somehow. The conventional wisdom was to install a water softener, but besides the cost we also didn’t want to add salt to our excellent tap water. So I did some pretty exhaustive research and settled on this device instead. It seemed a little like science voodoo, but I figured if it didn’t show results in a month or so I’d return it and get the water softener if I had to.Well, it did show some results, and then some more. It seemed like magic at first, but the shower heads just stopped having powder and sediment building up. The dishwasher did the same, and the taps seemed to run clearer too. We noticed the water felt different when washing—at first we told ourselves we were imagining it, and maybe we were—but soap began to sud better, and washing hands or in the shower felt less “scaly” than before. Also less water spots on surfaces. Then it just kept happening like that, and seven months after install we have absolutely no powder on the dishwasher we use almost daily, the shower heads look the same as the day they were installed, and the water has a “softer” feel. It’s NOT actually softer at all—the TDS is about the same, and the six month water test at both the well and the tap are basically identical to when we first moved in. So I’ve experienced enough to say for us, this thing works—works like a magical charm!—money well spent and im so relieved not to have to put salt in my water and maintain a softener system. I also sleep better knowing the dishwasher, washing machine, and fridge won’t get gummed up with the great minerals that are in our well water.A few items I’ll note here that might be helpful (as others’ were for me as I researched this): our well water is moderately hard, and the hardness mostly comes from calcium and iron. I don’t know how effectively this device would work on other types of hard water. We also are fortunate to have an indoor water heater and a large crawl space, so I was able to install the device after the well pump but before the water heater (this protecting it as well, I hope). So the iSpring is covering both our cold and hot water, which may not be possible in all well system setups. The install wasn’t difficult, but wasn’t exactly simple either. At one point I had to call the customer service line, which was picked up promptly by someone like it was a cell number!…and after I recovered from my surprise at getting a real human right away, he talked me through the issue I had (direction of wire wrapping) and solved the problem in short order. Last, this is the 7 month mark only—I’ll return to update if issues start happening past 12 months. Since I have a brand new plumbing system, anything that occurs will be a good benchmark for the longevity of this product.Overall, I’m an iSpring convert—it works for us, and has made a huge difference in our water quality and confidence that our new really expensive appliances won’t get gummed up with mineral deposits. It still kind of seems like magic, but science can be like that…and, so what, it works! I’m a happy customer.

I had a conventional water softener which was aging and had stopped working efficiently. I didn't like the effect it had on the water, always salty and a little slimy feeling after a shower. Lots of option for Salt free but I wanted something inexpensive and low maintenance. This system was easy to install and with a few new SharkBytes and some 1-inch PVC was able to make set up loop for the ED2000. A few months will see if its doing the job looking at the showerheads and if they get crusty or not.

I put the system in 6 years ago and was very happy for the first 4 1/2 years. Then, after one of my regular filter changes, my water pressure dropped drastically. We're at the point where you can't wash your hands after flushing the toilet until the bowl has finished filling.I am 100% sure it's their filters because a) I've checked the pressure coming into the house, which is fine and b) when I use the bypass around the filters, there's no problems with pressure.I don't know if they started using a new manufacturer or what (BTW, this company was outed several years ago for putting "Made in USA" on filters that were actually being made in China), but they have ZERO customer service. There is no customer service number on their website and when you call the main number you get voicemail and calls are never returned. They do have a customer service email address listed on their website, but NEVER answer emails. Finding 3rd party replacement filters has been impossible.Do yourself a favor, if you're installing a whole house filtration system, AVOID iSpring and find a company that actually has customer service and/or has 3rd party replacement parts, so you're not locked into their parts when something goes wrong.I'm now faced with replacing this entire system after just 6 years.

This is exactly what we needed for our tankless water heater. The amount of build up that collected from just a month of use was crazy. This descaler is a tremendous help. I would definitely buy again and I recommend to all my family and friends.

Really works. Will be getting a second one because it home is quite large. Water heater went out and when we drained it all the calcium inside came out like jelly. The faucets have begun to lose the calcium buildup. Very impressive.
