iSpring WGB21B 2-Stage Whole House Water Filtration System with 3/4 inch Push-Fit Braided Stainless Steel Hose Connectors and Ball Valve

We have horrible water where we live and after some research decided on the iSpring 2-stage filter system, which turned out to be a great choice for us. My wife and I are not plumbers and have very little plumbing experience but decided to do the install on our own. Our home is a newly built house and has Pex waterlines, which we had never worked with before. A little more research and we decided to use Shark-Bite connectors. Even though they are a little expensive, they looked the easiest to install for novice plumbers and matched the connectors that came with the filtration system. We took our time to make sure we had clean, even cuts on the Pex and used the Pex tool to make sure it was a smooth surface so we wouldn't have any leaks. Overall it took us about 4 hours to install the system. When it was installed, we were able to charge the system and were happy to have no leaks once it was pressurized. The happiness didn't last long as we quickly noticed the household water pressure dropped to basically zero. We thought maybe we installed something incorrectly, so we took out both filters and ran the system, and the pressure was normal. We then installed just the sediment filter, and the pressure was still normal. After installing the carbon filter, the pressure again dropped to basically zero. I did a little more research and saw online that carbon-block filters can cause a huge reduction in water pressure and that it might be better to use a granulated carbon filter instead, which I found really frustrating, and I wished I would have looked into that ahead of time. The next day I called iSpring customer service to tell them about my issue. The customer service agent was super nice and said sometimes the carbon filter can be blocked and that he would send out a new one and hopefully it would resolve the issue. I was sceptical but had nothing to lose at that point. We ran the system with only the sediment filter installed for a few days with no issues, and once the new carbon filter arrived as promised we installed it. We charged the system and had full water pressure throughout the house, and everything has been running 100% perfectly. The filters come sealed in plastic, and even though the filters had the same part number, the new one had a bigger/different label. We're not sure if the first filter was from a bad lot or if they redesigned something to make them work better. I'll be ordering some additional filters and will make sure they're the ones with the newer label.I'm giving the system 5 stars not only because I think it turned out to be a great product and easy to install but also because of the great customer service. They actually answer the phone and then sent a the new filter as soon as I described the issue.

This is the second ISpring filtration system we've bought in the last two months. We put one in our main house after discovering how bad our city water has been. The system is well made, the directions for install are very clearly written & it fit perfectly in the limited area we installed it in. We've been so impressed with the difference in our water quality that we purchased another system for our garage that also has an apartment. For what we paid for these systems, they are phenomenal!The rest of the story is that we've had a problem with the canisters sealing properly so I called into the ISpring customer service and got Nick on the phone. I explained what was going on and he immediately diagnosed the problem being that our installer had over-tightened the canisters causing the O-rings to flatten & therefore not seal right. This is no fault of ISpring Company, but Nick was just wonderful and is sending us new O-rings to replace the ones we damaged and gave me specific instructions on tightening the canisters going forward. He has also followed up with me regarding the replacement O-rings & wants to make sure when we get them that it takes care of the problem!The Customer Service we've received from Nick mirrors the quality of the system and I highly recommend both the system and the company. We could have spent hundreds of dollars more on other systems, but I doubt if we would have gotten better water filtration than we got with ISpring! We noticed immediately the difference in the taste of our water, the lack of white film on our glasses and sinks, and an absolute relief to dry, itchy skin & hair breakage from our showers!

I chose this filter system because my main concern with my water was chlorine and other pesticides when showering, washing hands, brushing teeth or washing cars. We have a separate under-sink 3-stage filter for drinking water that also removes heavy metals. Anyway, I was impressed by the 15 GPM rating on this item. Installation was a breeze with the included braided hoses. I used pex pipe and fittings that added another $75 in parts for my setup. After installation, I literally had no drop in water pressure! My incoming pressure usually hovers unregulated at just under 80 psi which is about the maximum you want for a residential application. Mostly it’s between 75-80 but on very rare occasions it may go up to 90 psi. According to the label on the filter canister it says it’s maximum operating pressure is 90 psi so I guess that saves me adding a regulator that would have limited me to 70 psi. I have to say I love the strong water flow that comes with 80 psi water. The largest GPM user I have is my water sprinkler, and after testing it there was no reduction in the distance it could spray. And immediately, we noticed no more smell from our faucet water. There was no aftertaste when rinsing after brushing. Also, filling the bathtub no longer smelled like we were at a pool. This item works just as it advertised. Couldn’t be happier for the price. Would recommend to everyone who doesn’t drink straight from the tap. If you plan on drinking from the tap, consider a 3-stage unit.

works great, easy to install. Watch the fittings on the braded hose, I had one that leaked and did not use it, just used pex to tap into it.

Acceptable shipping, good quality, detailed installation instructions, and it's working, the water quality is remarkable.

We have city water & this immediately improved the taste of our water. It was simple to install & only requires some basic DIY skills. There are plenty of youtube videos of people explaining the installation process if needed.
