Great Water Softener
We have had this system over a month now and love the way our water feels. Setup was pretty easy. Hardest part is getting the media in the assembly. If there is one thing to complain about it is that we go through more salt than i thought it would. However, the water feels great and the system basically does everything on it's own. Also, the customer support from Isopure has been great answering any questions i have had.

After 23 years of using two different Culligan water softener systems at two homes, I grew tired of how expensive they are. In addition, the Ontario, CA branch service representative never returned my call regarding my broken and now discarded control valve. I discovered Isopure Water about two years ago in selling reverse osmosis (RO) filters for my Culligan RO system at 33 - 50 percent less, which have been working great. I had to replace my RO storage tank about one year ago, which was 50 percent less than Culligan's with one from Isopure Water, which has been flawless as well. When my control valve stopped working after 13 years, ion exchange resin approaching its useful life, and no call back from Culligan, I decided to check options at Isopure Water. Tai at Isopure Water called me back in about two hours and based on my Culligan size suggested a comparable Fleck water softener. With some connectors from the local hardware store, I was able to easily re-plumb my piping to accommodate the Fleck, that was originally plumbed for the Culligan system. No pipe sweating needed. The Fleck has been working great. My only issue is the salt storage drum/container. It seems to be a modified 32 gallon round trash can with very thin walls. With my 13 year old Culligan storage container, the walls are thicker. Besides the thinner salt storage container, I would not hesitate in buying another Fleck. Isopure Water has been great to work with and Tai has been very responsive.

Nice softener - Great Customer Service
We picked this unit up at their store which was harder to find than I thought. It's a small store front but a good selection of items inside. I didn't realize they shipped most of their items but they allowed me to order and pick up this softener. They even helped me program it before I took it. I did my shopping and they were well priced but not the cheapest online. Did some digging and found out that their quality of items used were actually better than some of those cheaper companies. My plumber didn't have any problems installing it - probably took less than 1 hour since most of the lines were there. I would definitely recommend them to anyone who is buying one.

outstanding water softner
I installed the unit about month ago. The installation and programming were easy. The softner is treating my well water with 39 grains hardnesss with soluble iron. The softner has worked great. The water is perfect very soft and no iron. I was so impressed with this unit and my experience with isopurewater that I order a reverse osmosis unit from them. The RO unit has also been outstanding and so has isopure's customer service.

Questions & Answers

Q: What is the difference between an upflow and a downflow water softener? I'm replacing a softener with the mineral tank and timer in the basement and the brine tank located in the garage on the main level approximately 15' away and 5' above the control valves.
Asked by:  - 2/6/2014 (Submit an answer)
A: First off, you NEVER want an upflow softener. Upflow and downflow refer to the actual flow of water through the resin when it is in service mode. You always want a downflow valve. If you want, we created a clip of how a downflow softener should be on the "Water Softener" category page under the tab "How does a water softener work".

The only time a softener valve runs in a upflow motion is during a backwash. This is done to lift the bed and remove the sediment in the softener.

Downflow (during service mode) is required to force the water to come in contact with the resin in order for it to exchange the hardness ions in the water with salt ions.

I hope this answer helps you.

Q: Can you explain the difference between the metered and the digitial readout? I wanted the one where it automatically detects the water/salt and regenerates automatically instead of everyday at 2:00 a.m. Thanks
Asked by:  - 10/19/2014 (Submit an answer)
A: There are a few minor differences. Both valves will regenerate on demand (neither will regenerate every day at 2:00 am unless you set it that way). The digital valve has more control on the functions of each setting. A mechanical valve can only control the number of gallons used before regeneration (max at 2100 gallons), time and salt. The digital doesn't really have a max number of Gallons before regeneration and you can control a few extra settings such as hardness, and back wash minutes. Other than that, they are practically the same valve.
