Review: Great quality parts and system. WORTH IT! - WORKS INCREDIBLE! I have had for almost a year and we love it . I installed myself and re-order changing the direction from left to right.
Review: WGB32B iSpring Whole House Water Filtration System - We live in a small town that has experienced frequent periods of discolored water for decades. We'd see it in our toilets, sinks, and bath tubs, knowing it is in our food as well. It would last a couple days and be gone. We purchased a 10' x 10' x 30" kiddie pool for the grandchildren, set it up, filled it, and the water color was disgusting. It was almost the color of tea. We drained the pool, washed it out, and purchased a small filter that attaches to the garden hose. Refilled the pool again and the water was again discolored, but not as bad. Drained the pool again and put it away until we could resolve the water issue. We didn't need a water softener, nor did we want the purchase and upkeep expense for those types of systems. We did research online and found that iSpring filter units kept popping up as one of the top three best rated whole house filters. They're competitively priced and installation looked straight forward. We found the unit that we believed best suited our needs and purchased the model WGB32B unit off desertcart. This unit came with three filters; 5 micron particulate and two carbon filters. It arrived in a few days, and after reading the instructions I decided to install it myself. Our house has CPVC water piping so that made things easier. A trip to the hardware store for $50 worth of pipe and fittings and we were ready to be "plumbers". I first mounted the manifold unit (minus the filter housings) securely to the wall next to the main water supply line. Don't skimp on secure mounting as this unit is fairly heavy (maybe 40 lbs dry), even with out being full of water. I laid out the piping and fittings in the configuration I'd draw up before starting, cut the piping after some measuring, and "dry fit" (not glued, only hand fastened) everything together. After some adjustments, I shut off the water main, drained the pressure, and as much water that would drain. I cut into the CPVC main line at a predetermined place, drained residual water, dried the piping off, and started installing the piping and fittings, gluing them together starting at the main water pipe and working my way around the filter piping system. Once together, I allowed the glue to cure for an hour. While waiting for the glue to cure, I installed the cartridge filters into the housings and installed them onto the manifold, snugging them with the included wrench. After an hour, time for the leak test. I had all faucets in the house open. I slowly cracked open the main water inlet valve and slowly closed each faucet in the house. I could hear water filling the cartridges as the air was being pushed out of the system. Once the air was purged, and all faucets closed, the system came up to full house pressure. No leaks! I closed the filter bypass valve and we opened the closest faucet to the iSpring system and allowed water to flow for 10 minutes as instructed in the directions to flush out any carbon particles (didn't notice any visual carbon particles). Checked for leaks again. All good! We ran water in each faucet to flush the house system for about 15 minutes. Checked for leaks AGAIN. All good. Still not leaks. A couple installation notes: 1) For the threaded connections on either end of the manifold, I used 12 wraps of Teflon pipe tape AND a coat of good pipe sealant on top of the tape. The instructions said this could be a leak point, so I took no chances. I carefully tightened the adaptors into the ends of the manifold. I did not "bottom them out", but was a few ticks tighter than "snug". The manifold is a type of heavy plastic. I was using PVC fittings, but if you're using metal, be careful. Over tightening could crack the manifold. 2) As stated above, use heavy hardware to fasten the unit to the wall. I used a 2" x 10" board screwed into the wall studs with nine #9 x 3" deck screws, then lag bolted the manifold to the the board. The heavier the better. Do not use wall anchors in drywall! Do not use small screws such as drywall screws! If you have to, build a mounting bracket. 3) I installed a low point drain on my system. When it comes filter changing time, I wanted to be able to close the inlet and outlet filter valves, open the bypass valve, drain the pressure and and much water out of the manifold as possible. I can also use this as a low point drain for the house system if that's ever needed. I encourage you to do this as well. 4) I did not install union fittings in my system. This would allow removal of piping without the need to cut the pipe. If I had anything that I'd change, that would be it. I trusted my threaded sealant and gluing, but any leaks and I'd been cutting CPVC pipe out to fix the leak(s). We've only had our iSpring system up and running for one day, but we could tell a difference immediately. The water in our white porcelain toilets is actually CLEAR. It'll be interesting to see how long the particulate filter lasts in the conditions we experience with our city water. I expect 6 months with our city water condition. We shall see. I registered the iSpring system online. I received an email from Sean within an hour thanking me for the purchase and telling me to contact him with any questions I might have about the system in the future. So far, we couldn't be happier with the iSpring system. I am confident we made the right choice and look forward to not worrying about the water we use and consume.

## Features

- Protect Your Family and Household Appliance from Chlorine and More: Say goodbye to smelly, bad tasting water! The FC25B carbon block water filter is specially designed to remove up to 99% of chlorine from water as well as taste and odor compounds, cloudiness, and chemicals.

- Top-Notch Quality: Our FC25B CTO Carbon Block filters are made of high-quality coconut shell activated carbon for maximum filtration efficiency and filter life. Activated carbon is an effective adsorbent because it is a highly porous material and provides a large surface area to which contaminants may adsorb. This whole house water filter is tested by an independent third-party to meet NSF/ANSI standards.
- Peace of Mind Customer Service: Register online to activate your manufacturer and life-time free tech support from U. S. local support team. We stand behind our products and if you encounter any problems with any of our water filters please reach out to us immediately. We are happy to help!
- Please Note: The water filter cartridges are individually wrapped to ensure freshness. Please unwrap the cartridges before use. Unlike an RO membrane, the filters don’t reduce Total Dissolved Solids (TDS), and instead keeps healthy minerals in your water. If you are interested in a filter that removes TDS, consider our iSpring Reverse Osmosis (RO) systems.

## Questions & Answers

**Q: We are looking to install this in a seasonal cabin, can this be winterized?**
A: Hi Cate,

This unit should be protected from direct sunlight or freezing temperature.  Depending on the environment in the winter, the housings might become damaged. Please contact us with more details so we can better assist you.

**Q: I received this whole house filter and one of the cartridges is broken model fc25b. can i get a replacement of this broken cartridge?**
A: allfilters.com 
I used iSpring for a while and then the types of filters ordered was so confusing......and its all made in China.......unlike advertised. So I switched to allfilters....now keep in mind that they don’t send one at a time....but the price difference, the nonconfusion, sent by USPS and customer support won me over. ALL MADE IN THE USA! Allfilters also sells the canisters. When ordering filters go by the size ei: 4 1/2” x 20”

**Q: Do you still need a water softener with this if hardness is 250 ppm?**
A: Hi there, It's optional but would help p[rolong the life of the filters if you install one. We usually recommend a water softener with TDS higher than 700 PPM. Please let us know if you have other concerns. Stay safe!

**Q: What pressure gauge is recommended to install pre and post filter that will work with 3/4" PEX supply line?**
A: I use the one on a spin down pre filter and a 
3/4” shark bite with gauge post filter
