iSpring UVF55FS Whole House UV Water Filter with Smart Flow Sensor Switch, 55W, 12 GPM

This is my first time on a well, and I found that I had issues with both e-coli and also heavy metals. Nick has been fantastic in helping me to deal with my well water issues through the uvf55fs for ecoli and the whole house two stage filtering. These days I don’t expect much in the way of customer service but I Spring and especially Nick have gone above and beyond to help me. Thank you so much.

Always has worked well. Recently had a problem with uv and customer service was excellent. Sent me a new bulb at no cost, even though unit was not in warranty.

Cust support is great. Product is wonderful. Only hiccup was i had an old manual with the old ballast picture. They upgraded the ballast and some old manuals were already shipped out. 1 call to cust service and question solved. All good.

I have never had as much difficulty with leaking fittingS as I did with this unit. The brass fitting for the flow sensor would not stop dripping a slow drip. After three times refitting I finally stopped it with white pipe threading compound (a lot of it). I did not find the brackets particularly helpful as they seem to be a bit too small to fit unless you had it perfectly squared up. Finally, my ballast has a two position switch, not three as shown in the videos and there were no instructions provided on the operation of the switch. After some trial and error I figured out that when you see the 300 second countdown you are on auto.Overall it appears to work well. I would have given it 5 stars if proper instructions were provided and if the included two brass fitting rather than only one. ALSO CAN'T FIGURE OUT HOW TO REGISTER IT FOR WARRANTY.

Item shipped immediately, everything came in complete as advertised. Our glass tube was broken and upon discussing with Michele in customer service a replacement glass tube was sent out immediately. Michele was wonderful to work with. Only have had unit installed for a couple of days but very happy at this point.

I am new to installing these things, but disappointed. After setting up my system, resolving leaks, and having everything else work I was excited for this to work and finish the whole water system.I plugged in and all I get is beeps. I have no idea what is happening. I read the manual and beeping means to replace the tube. but why would I replace the tub when I just installed it lol? Now I gotta shutoff this part of the system, drain the water, and buy another tube? Even after following the instructions on proper handling and installing to my knowledge correctly?And even then, what if that isn't the issue? I buy another tube and all it does is keep beeping at me? Not worth it.Save your money buy somewhere else that actually works and doesn't just beep at you. We just have to take the loss right now and hope that in a few months when I do buy another quartz tube because the one came apparently isn't quality enough that it is the actual issue.But most likely we'll be prepared to just buy a better product.

I bought the UVF55FS for my rainwater system and it's working great! At first, I thought I'd wasted my money because, after completely flushing my entire system, a coliform bacteria test came out positive. It did it again after a second complete flush. I finally realized that bacteria are pretty sticky and some will inevitably remain stuck to the sides of the pipes, even after multiple attempts to wash them out. So I decided to fill the whole system with a strong concentration of chlorine bleach and I let it stand for 3 hours. Then I flushed the entire system out again until all traces of chlorine odor were gone. I continued using the system for washing but not drinking for a few days then retested for bacteria. This time, the test showed ZERO bacteria. I even let the test incubate for a couple extra days to be sure.One thing I'd recommend is NOT waste your money on the version that I did with the flow sensor. I think the flow sensor is a bad idea now that I've had some experience and more time to think about it. For one thing, the flow sensor will not turn the UV lamp on until flow rate rises to 0.66 GPM. So if you use this mode and you run some water at anything less that this rate, the bacteria-contaminated water entering the UV unit can pass right through without being sterilized. Another problem is that even when the lamp turns on, it will take it a while to come up to full intensity, allowing more unsterilized water to pass through. Yet another problem is that the lamp may not last as long if it's continuously cycled on and off. Therefore, I'm leaving mine on 100% of the time and expect to replace it in 1 year.A few corrections for the manual:On page 4, it incorrectly states the maximum water pressure allowed is 43 PSI. Page 3 apparently has the correct spec which is 85 PSI. It's also stated on page 12: 4 PSI min / 85 PSI max.On page 4, it says to make sure the inlet is at the bottom if you mount the unit vertically because they incorrectly say it will slow down water flow. It won't slow the flow regardless of putting the inlet at the top or bottom. The only way their statement could be true is if the bottom port was left open so water could fall out with no back-pressure. When installed in your home's water system, the difference between pressure-tank pressure and the back-pressure is what determines flow rate, not the orientation of the UV unit. Orientation doesn't effect this at all.On page 8, it says "Mode AUTO is highly recommended to protect the UV lamp.". Not true and definitely NOT recommended.On page 9, it says the "system is designed for continuous operation, and frequent switching will reduce ultraviolet radiation and service life." which directly contradicts the statement on page 8. I believe this statement on page 9 is correct and you should ignore the AUTO mode recommendation. Don't even purchase the version with the flow sensor so you won't have an AUTO mode in the first place!Note that if your home experiences a power outage, unless you use some kind of uninterruptable power supply, your UV sterilizer will be off and any bacteria and viruses can then pass into your potable water system when you turn on a faucet. Mine is on solar with battery storage so is much less of a problem but I still may add a UPS for the UV unit.Lastly, I DO highly recommend this unit after seeing the bacteria test results.

I ordered this UV Filter as the last leg of my Whole House Water Filtration system. It was working great until the Ballast with Flow Sensor stopped working a few months after the installation, which kept the UV bulb running 24/7 and reduced the life of the UV bulb. I contacted the iSpring customer service and spoke with Nick. He was super helpful. He shipped out a 3rd generation Ballast with Flow Sensor, along with 2 UVB55FS bulbs. The order was delivered within a few days and I replaced all the broken parts. So far everything is working great. I appreciate the help I got from Nick. Will definitely buy their products again in the future. Thank you Nick!
