The installation of the UV sterilizer is pretty straightforward. I used 1" Pex-B with clamp style fittings, to match the 1" of the filter system. The system is exactly what I was looking for and performs as expected. As shipped by desertcart via FedEx, the UV bulb arrived shattered, and the damaged package was also missing the o-rings, but the rest of the system was ok, and I did not want to return the whole system. Luckily, desertcart was able to issue a partial refund for just the value of a replacement UV bulb. I ordered a replacement bulb and it arrived within a few days, this time undamaged. I also emailed Nick at iSpring customer service about the missing o-rings, and he immediately responded by email and shipped out a replacement set of o-rings which arrived very quickly via USPS. I call that very prompt and excellent customer service! A few more notes on the system: it has a smart controller with the bulb ballast integrated. This controller connects to the UV bulb, to the AC power, and also to the flow switch to turn the UV bulb on as soon as water flows. This is indicated by a green LED. When flow stops, the controller keeps the UV bulb on for another 5 min (300 sec) to avoid excessive bulb power-ons, which would reduce bulb life. After 300 sec, the bulb is turned off and this is actually shown via a 3-digit LED count-down on the controller, a nice feature! If within 300 sec the water flow is turned back on, the counter is reset to 300 sec. Overall, I really like this flow-through water sterilization system. It has a very high build quality, and is easy to install, and works in a fully automated, worry-free way. I would highly recommend this as an add-on to any home/whole house water filtration system. Review: Easy install, great support! - Super easy to install, but a little finicky with the threads (at least for mine). My first attempt at hand tightening the sensor switch had a small leaked, so I slowly tightened it further to get it to stop. Unfortunately, it appeared I ended up damaging the washer by over-tightening it, as I couldn't get the leak to stop. Sean at customer support was awesome. Sent me a replacement sensor and washer, which resolved the issue. On the other threaded connection, I used sharkbite fittings for my installation and found the brass (sharkbite) to stainless (iSprings) connection was a bit finicky. Had very slow leak using only pipe tape. Removed and cleaned everything and re-applied the teflon tape and added a layer of plumbers dope and it sealed up nicely. Highly recommend, especially if on a well system (as we are). ## Features - Whole House Water Treatment: As the upgraded version of UV water filter iSpring UVF55, UVF55FS is a last step to add to your whole house water filtration system and give you the peace of mind of knowing all of the water in your house can be treated at once - Upgraded Ballast with Flow Sensor Switch: Ensured actual treatment with water's long dwell time in the 37.5-inch 304SS reactor chamber; a 12 GPM flow rate and minimum pressure loss with 1-inch MNPT inlet/outlet design; a quality 55-watt UV lamp(UVB55FS) in durable quartz sleeve has a long bulb life of up to 9,000 hours; upgraded 55W ballast(UVT55FS) with smart flow sensor switch(3 modes: Auto, Move, Stop) makes it easy to control and monitor system performance.
