iSpring Whole House Water Filter System, Highly Reduces up to 99% Chlorine, Sediment, Taste, Odor, 3-Stage Water Filtration System w/Clear 1st-Stage Housing, Model: WCB32C, 3/4" Inlet/Outlet

**2022 UPDATE** The head unit started leaking outside through one of the screws on top. Definitely a crack of some sort. I called support to ask if there was anything I can do to fix it and Nick said they would replace the unit entirely. I was floored at the level of customer service. You literally do not get this kind of care/support anywhere. Thanks goes to Nick and the iSpring team! First off, shout out to Don who works at ispring for helping me out. TL;DR - Great Unit, Don at iSpring was extremely excellent, if I had a chance to do-over, i might have gone for the bigger unit (most likely will if I ever replace this one) I bought this unit in 2019, but didn't install it until I moved into my current house. Boy oh boy was it a nightmare getting in. I'm a DIYer and love a good challenge. I'll spare my details, but basically I had to change where I mounted it because of the location of the water line coming in and the space around it. Note* I did not install a bypass, but rather an inline-leg. So to change the filters I have to shut the water off at the house. I'm fine with that, but others may not be. Once installed tho, the water chambers filled nicely. Water started flowing. About 2 mins later, the unit started leaking at the in/out female connector. That was my fault, not enough Teflon. But the male/male connectors in between also started dripping. I called support and spoke with Don who was very informative and helpful. He suggested different Teflon (Blue Monster - excellent stuff more on that later). He was also shocked about the leak in between the filters so he said he would send a replacement head unit. Unit arrived and unfortunately it was a new model type where the filters were closer together so I had to cut my pipe up a bit to make it fit. Teflon Blue Monster, YMMV, but I put 6 wraps on it and put the male connector in, then backed it out to put 4 more wraps on it. The 6 wraps formed this nice plastic sheath/coating on the male connector so I knew it would make an excellent seal this time (the original Teflon I used was like 4 wraps of cheap lowes stuff, and it disintegrated as it came out). New unit in place, turn the water back on. No leaks on the in/out connection. However, the male/male connector in between the filter did start to have water form up. I took pictures and sent them over to Don. I opted for compensation of 1 set of new filters as I would rather not have to install another head unit. IF/When the leak progresses , I'll see if I can wrap the connector units with blue monster as well. Water taste is great, I love that it's 0 waste and the whole house has nice clean water. It's so comforting to know that even my toilets are filled with purified filtered gold. Hopefully this is helpful. If you take nothing else away, know that my case is unique. I don't think it happens often. But iSpring WILL take very good care of you.

Why did you pick this product vs others?: I am building an off-grid tiny home (Ohana) in Maui for my father in law. Materials and equipment are expensive and hard to find here, if ever in stock. So ordering this filter system from Amazon is a life saver, and cheaper then I could ever find direct on island. I installed the iSpring WCB32C filter in my pump house over the weekend and got the pumps running for the first time under pressure. I only had the smallest leak from one of the canisters. I quickly discovered a small nick on the one O-ring that likely is causing he small drip. I could only see it by pulling the O-ring out and inspecting it very closely. When I bent the rubber on the O-ring slightly I could see the crack in the rubber open up. I likely would not have noticed it if I did not bend the rubber during inspection because it was so small . I could have pinched it slightly while screwing the canisters on the base if it was not seated correctly, or it could have been a minor flaw in the O-ring, hard to say. Either way Nick with customer service was super friendly and fast to order me a replacement. I emailed them on Sunday and got the response first thing Monday morning. In the meantime, I just have a can under the one filter to catch any slow drips until the replacement arrives. I am confident when the replacement O-ring shows up this week it will fix my problem and the filter will work perfect for what my father in law needs out here. Since our water comes from a rain catchment, it is important to filter and have no issues with drinking through this iSpring system. The filter quality is more than enough for what we need. Some people advertise and talk about the newer ultraviolet filtration systems now, but don't really understand the need being that a lot of us grew up on water catchment with simple filter systems. As long as you make your tanks are clean and have a pre-filter system to ensure this, we never experienced or ever heard of anyone else having any health issues. I just feel like the UV systems are another thing used to scare the public into using a product that is overkill or something above and beyond what they truly need for health. The filtration systems iSpring offers is more than enough to maintain a safe lifestyle. If I had to offer advice for anyone ordering this system, just check the O-rings very carefully before you install and it might save a step. Also, I should have dipped the O-rings in water before screwing the canisters onto the base so that they were a little more lubricated and hopefully don't pinch along the edges as it gets tightened up.

Overall I am very happy with this purchase. We live under 20 miles from the Ohio train derailment so as an added precaution, adding an inline whole house water filter just makes sense. Our drinking and cooking water has always come from a 5 stage reverse osmosis system and this 3 stage filter shares the same types of filters as the first 3 stages of our reverse osmosis system (minus the actual reverse osmosis membrane and post filter). The good... Shares same first 3 stages of filtration as the reverse osmosis systems. Ease of installation for me was pretty easy but that will absolutely depend on the installers abilities as well as access to your main water line. Fortunately for me, the house once had a water softener so there was a bypass valve already in place. I simply had to tie the filter in and open the valve. Tap water tastes fine but again, this is going to be subjective. I am used to reverse osmosis water and I intend to continue using reverse osmosis for drinking. As with any inline filter, everything downstream should benefit including water heater and appliances. Another benefit is that my reverse osmosis systems are essentially 8 stages instead of 5 and I expect the filters to last longer so there should be a little bit of savings in that aspect. Filters are relatively inexpensive and readily available. The bad... My only complaint is somewhat trivial. I plumbed my water into this unit with PVC. I used a 90 degree adapter right at the filter inlet and outlet. The metal frame of the unit was in the way of being able to fully tighten the fittings and had to be removed, then reinstalled once fittings were in. If you use PVC, DO NOT use Teflon tape. It will leak! Instructions say to use 2-15 wraps of teflon tape. Just use thread sealant and save yourself the headache. Overall... I'm happy with the unit. Just a little reassurance that your water is being filtered, sediment, chlorine and other items are being removed/reduced. I expect appliances to last a bit longer, the water to be a bit healthier and to that, there really is no downside.

Amazing whole home water filter. Very easy to install. I had a small issue with the o rings and Sean from support quickly sent the right parts i needed. So happy to have clean water for my whole home in such a durable easy to maintain package.

Update 2.7.22. These filter housings are the worst I have ever installed. It took 3 attempts to stop the leakage from the female threaded housing. I used triple-thick Teflon tape and T2 Dope reinforced with fibers. I wrapped the triple thick tape 7 times and then applied a thick layer of pipe dope (the best they make of both). Let it sit for a few hours (though not required) and installed the 3 filter housings. Turned on the water and dang two of them leaked (though slightly). I tightened them a quarter turn and it appeared to stop the leak. An hour later a droplet appeared on both, I turned it a 1/8th of a turn tighter., so far so good, no leaking. If it leaks again, I will take apart the two fittings, put 8-10 wraps of the TRIPLE thick Teflon, and apply the pipe dope. Take my advice and follow my instructions or buy a different filter system. (my buddy a machinist said "the manufacturer made a defective threaded housing unit"). Besides that, I have plumbed dozens of homes and commercial projects, and never have I experienced such a poor-quality product. Needs to be recalled as defective. Update 2.5.22 7.36 pm. Took apart 6 threaded connections, used plumbers dope sealant and reconnected fittings, allowed dope sealant to set up for 1.5 hours, though the sealant does not require any drying time. Dang, It LEAKED again! I am again taking it apart and am going to use both Teflon tape and the dope sealant. ISpring unit is really poorly designed at the female thread connection. The first review today was @ 5.30 pm. I read the warnings from others installing this unit and the seller's recommendations. I wrapped the threaded connections 10 times with Teflon tape (the good Teflon stuff) I Turned on the water and dang all 6 threaded connections at the ISpring filter housings leaked.
