Product shipped incomplete, held up installation! Was given the excuse of "mistakes happen" and was told missing parts would be shipped separately.

My family had a 40-year-old Culligan water softener that was still working but it exhausted the resin. I have put new resin in before but recommended to my family replacing it since parts haven't been made for that on in a decade maybe more. I was a Culligan service repairman for many years so when I started looking, I wanted a Flech control body which is very dependable, and 1-1/2 cubic foot unit with a meter. When I found this one it was highly recommended in the reviews and priced very well. When I ordered it, it comes with an adapter for 1" plumbing. I needed 3/4" so I place an extra order to buy the correct adapter. The company reached out to me and told me if I cancelled the extra order, they would remove the 1" and put in a 3/4" at no extra charge. When it arrived, it was very well packaged, it had the correct adapter. Installing it was easy. It was missing a fitting, I could have missed placed it, it appeared to be a standard 1/2" threaded fitting. I called the company AND A PERSON ANSWERED THE PHONE, I was shocked but very happy. She said they could overnight it but yes it was a standard fitting, so I just went to the hardware store and bought it. Programming was very easy, I had 1 question and again a person answered the phone, quickly answered the question. It has been in about a month, and everything is great. THANK YOU, THANK YOU

Excellent product. Works great, nice, soft water. Price is right. I hired a plumber for the piping which was a good idea. Added a faucet for car washing.

I had a Kenmore survey that went out, replaced it with this. I'm a jack of all trades, master of none, and this felt pretty easy. Took me about an hour to install the new lines, put this together, then set up. The manual that comes with it is set up kinda dummy proof, but its only going to get you in the ballpark, you'll need to know your water levels to get it dialed in. I have a friend who installs these and the settings he gave me were not too far off. The standard setup fills the tank much more than I'm used to seeing. Refill is on a timer and fill flow is pretty fast, so I had to adjust that down so that it's not filling too high. Our water is next level soft now, didn't realize how ineffective y last softener was until now. Also love how these are so easy to rebuild and replace instead of buying a whole new all in one system you get in retail stores. Can't sing the praises of this softener enough.

I paid a local plumber to install it for us, and it started out great. The water has a very slight salty taste and consumes about one 40lbs salt crystal bag every six weeks. After six months the unit stopped working and flashed "Err 0" when trying to run a regen cycle. After power cycling it started up okay before going back to "Err 0". I called the Fleck/Pentair customer service number in the warranty book and was told I need to order a new piston and valve spacer which are "wear items" not covered under warranty. UPDATE 6/28/22: Seller Aplus Water LLC were incredibly helpful, and sent a replacement valve at no cost. They sent a return shipping label for the failed valve so they can inspect with the manufacturer. They sent a link to an instructional video they had made, and with that I was able to replace the value in about an hour. It is once again working perfectly. Thank you Heather at APlus Water LLC for resolving this promptly and easily! We are again very happy with our purchase.
