Bought this for my home to deal with questionable city water. Sometimes it tastes weird/like chlorine and will leave our bathtub, sinks and toilets a wreck. Not to mention the horrible calcium build-up in the lines needed dealt with. After spending roughly $50 in parts (PVC), I set to work. The installation only took maybe two hours while taking my time. I also needed to reverse the flow of the filters, which the instructions to do so are provided. I've got to say, after everything was said and done, I was impressed with the immediate difference in the taste of my water. I had some of the "old stuff" just in case I needed it, and compared to drinking the water after the filtration system, the old stuff smelled and tasted like I was drinking water straight from a pool. After the filtration system? It actually tastes like nice refreshing water. Not only this, but I swear my skin feels better after showering to boot. The only hiccup I experienced was that one of the gauges wasn't working initially, but after a suggestion from customer support I found out it was 1 turn too tight. All gauges work correctly once I loosened it a full turn. While it may be too early to give it an honest, long-term review, I'm impressed with it so far. If you're looking to improve your water quality, you can't go wrong with this system.

Water quality in out area was very poor. Refused to drink it. Was tired of taking trips to the water refill station in the area and paying $4 for 10 gallons of water for our water machine every two weeks. I had it installed by my plumber with shutoff and bypass valves. Allows me to now turn the water off to the house at the filter. Makes changing the filters much easier also. We took the advice from another review and reinforced the gauge fittings. Blown away by the quality of our water now. Pure taste, hair and skin feels better, much better quality. I had this in my cart until prime day to save some money but is absolutely worth the full price. I just performed my first 6 month filter change, easy as shut the water off, unscrew the basin that contains the filter with the provided tool, dump, replace and tighten. As someone else noted, you may see a dip in water pressure. I did have the plumber slightly increase my water pressure to help with this. There are times where you may notice a drop still like when starting the shower. Just give it a min and it will catch back up. Its never a long lasting issue, at least in my experience. I think its something to do with the 3 large filters having to ill with water and then fill the line, so the system is playing catch up.

****I'm am a plumber for 12+ years now. Review after a year. Must read**** Was looking for somthing for my house (city water) to benefit all my appliances, specially my navien tankless, as well as all you're usual appliances. As well as me and the family. Was going back and forth on very expensive systems and lower end. And always keped coming back this this brand. I'm am not payed by the c.o. Just sharing my experiences so far. I'm going to go right down the line. In no order. Some being much top tear. *I have noticed, showers you feel cleaner. *baths for the kids,soaps more soapier. * water much clearer. *fish tank maintenance, water can be used straight out the tap without conditioners. *washer,and dishwasher, (higher end lg front load and dishwasher) don't smell as much/ berry little from sitting. * faucets,shower head ends. Less build up on the end just from standard buildup. * i am a car guy with detailing, 100% +++ soaps much better both normal and my pressure washer with the foam cannon. Basicly a 3 stage, spot free rince you have. Cars are much cleaner. *pressure washing the house, not much but definitely makes a small difference. More so on windows. * i do water the lawn alot in the summer, just switch the house on bi pass is temporarily and good to go. *wife will water her plants( not many just pots and what not) she claimed to be just more fuller. * drinking the water, you don't feel as thirsty, wanting more. I'm on a roof during the summer and my 1 gallon yetti staying ice cold. I don't seem to go back more to want more. Now when I run out and just fill it up on the job sight. It's night and day difference of just wanting more. I'm sure I have more thinking on it but worth the by.

I bought this system and had my plumber do the installation. Saved a few hundred dollars overall by not buying the whole system from local plumbing contractors. Well built system that doesn’t require a lot of room. Maintenance is once a year.
