Customer service A++, product works perfectly, NO MORE STAINING
Very happy with this purchase and the assistance from their customer service. I received a damaged tank (not the sellers fault, it was damaged during g shipping). When I reached out to the seller they sent me a new tank without any trouble. A lot of respect for how much their customer service took pride in ensuring customer satisfaction is a top priority. As for the quality of the system, it works phenomenal!!! I used to have to change my double whole house filter every 2 weeks to keep up with all the staining my sinks and tubs would get from iron deposits. After installing this iron water filter my water is crystal clear and the double filters still look brand new 2 weeks later!!! Quality product. Superb customer service. Easy installation. Programming a little confusing but once again customer service was a phone call away to answer my question. I wish all companies operated at the quality that this one does.

Works excellent well worth the investment
Well worth the money. This is a great investment. Easy to install. Easy to program. The resulting water is incredible quality. Completely removes the brown/rusty water and prevents stains on fixtures. The water is crystal clear and no smells.

Not hard water , iron only well water excellent solution
Had a water softener and pre-filter 5micron , continuous maintenance , hassle with bags of salt in a very small area . Softener valve locked up and broke , never really solved iron problem , searched for alternatives for iron only problems without adding salt to water ( not needed, not hard water ). came across the 5600sxt air injection with natural catalyst that removes iron in suspension and also removes magnesium and some pesticides / chemicals through capture and backwash. Worth a shot because it can also be used with a salt reservoir if it was needed later , but it is not needed. Installed after pre-filter , added another clear body 20" post filter to be able to monitor condition of non dissolved solids . Performed initial setup as per instructions and after 24 hr set in first cycle then opened into system , instant success . NOTE: Installation , some plumbing knowledge is definitely needed. Water taste great , no discoloration at all and suprisingley not as loud as the softener used to be . The softener always left an oily film and strange flavor to the water , it tested fine but was not great . This new set up is much better than it ever was !

Careful not to use the default settings if you have a septic system.
This is a good product and is functioning as advertised. NOTE: If you have a septic field and use this unit in conjunction with a water softener do not rely on the default settings as this could overwhelm your drain field. The default settings are: regenerate daily for 15 minutes. This will potentially use between 75 to 120 gallons of water. If your water softener regenerates on the same day and uses a similar amount of water you could potentially drain over 200 gallons of water into your tank. Couple this with washing machine, dishwasher, toilet and showers and baths you will overwhelm your tank(s) which will stir up the waste and propel solids into your drain field. I have hard water with iron and have it set on every 2 days and 10 minutes with good results and no iron in toilets or laundry.

It actually works!
I bought this carbon filter setup with a healthy dose of scepticism, knowing that our water is about half iron. Well, maybe not half, but enough to stain our sinks and toilets in a few days if untreated, and it is distinctly orange out of the tap, even after going through 2 filters, a 5 micron and a 1 micron. I installed the system and let it soak with water for 24 hours as directed in the installation manual. I also drained my water heater and flushed it a few times. After the 24 hours and the tank had been flushed as per the directions I opened the bypass valves and the change was immediate, at least for the cold water. No sulfur smell and no orange color. The hot water looked very murky so I drained the tank again and flushed it twice, and then the hot water was perfect like the cold. Supposedly the carbon will last 5 years, and that is great. I do wish the company would include directions on how to empty the tank, how much carbon to put in it, what kind of carbon (I have found out what typy, and how to suspend the 1" pipe in the tank. I'll contact the company and get that squared away long before I need to replace the carbon. No more schlepping salt and dumping it in a softner and no more worrying about what water faucet to use when watering the gardt. Highly recommend!

Huge Water Quality Improvement for Well
We bought a house with a private well that had water very high in manganese. There was an old water softener in place that had bypassed years prior. When researching what to replace it with we settled on this unit. It arrived less than 5 days after ordering with everything in place and packaged well. It was very easy to hook up to plumbing that was already in place for the softener. APlus provided very detailed instructions with the unit on how to install the valve and get it programmed. Almost immediately after running it we noticed a substantial improvement in water quality. We no longer have rust staining water that smells and tastes bad. Overall we are extremely happy with this purchase and would highly recommend it as a cheaper, simpler, and more reliable alternative to the multi stage systems that may not actually do well at filtering out iron and manganese like this unit is intended to do.

Awesome easy installation. Connected right where the old one was, just needed some minor adjustments. Any home owner with some experience can install it. After the initial fill and soak of the resin it runs great. Our iron in unnoticeable in our water now. Delivered early too. Highly recommended.

Had a softener with a carbon filter, so much iron in the water still I had to clean the tub and toilet nearly daily I plumbed this filter before the softener and now my water is crystal clear! Been a month and zero trace of iron. I even took out my carbon filter as this filter took out the smell as well

Works great. Takes out the iron . All is crystal clear and I no longer see brown in the toilettes. Terrific service when I called Durawater to ask a question. I would buy again. Terrific.

system works great. easy to install and got immediate results. we now have clean toilet tanks and bowls compared to twice weekly cleaning without the filter. I had a question about the control head programming and the seller contacted me immediately with instructions on how to set it up for air injection filtration.

Used this unit for a rental property with a major iron problem. Tested at 10 ppm. Water would turn orange over night in toilet bowls. Easy to install and works great. No more iron problem at a much lower cost than other water shops could provide. Only reason I gave 4 stars instead of 5 was that the instructions provided are poor. Read other reviews and watched the video and no issues. Thought the unit was initially showing me an error code, but turned out this wasn't the case (actually was showing me number of days before next recharge). Company was very friendly and resolved issue. My only suggestion is to update your documentation, even if it is just the link to the installation video as this would be an improvement. I would buy again.
