"There is not much to say. The lamp is very easy to install, lasts the specified year, and disinfects the RO water as it heads to your faucets. A subscription for it prevents you from scrambling for a new lamp when yours expires."
— Debra D. (5/5)
"My replacement bulb for my UV light came and is now installed. Great service supporting the light warranty and getting the new bulb sent to me. Tom"
— Thomas K. (5/5)
"We were able to replace the UV lamp ourselves, with US Water's guidance, saving on labor costs. Also set auto reorder schedule to stay on maintenance plan."
— Joe B. (5/5)
"This Ultraviolet Lamp works fine I believe but if your not using your water system for 6 months it has a counter by days that you cannot reset thus causing an alarm that goes off signaling that it is time to replace it once a year. So, I have to purchase two of these in one year to stop the alarm."
— Steven S. (3/5)
"Love the whole system. I also wanted to show how dirty my filter was after one year. . . notice the comparison to a clean one."
— Scott D. (5/5)
"Great product. Easy to replace. Comes with new 365 day key fob for controller"
— Tim S. (5/5)
"When the UV light reaches 9000 hours the bulbs controller tells you that it needs replaced. The part came quickly and installation was simple with few tools depending on your installation."
— Mike S. (5/5)
"Love my us water systems setup. Bought a uv light several months in advance and never opened the box until it was time to install. Upon opening the box the light was broken which happened during shipping. At first us water system didn’t want to replace it but after several calls and explaining what happened they eventually replaced it and retained one happy customer. Thanks US Water Systems"
— Duane B. (5/5)

— Jeff M. (5/5)
