Looking for a value driven, alternative solution to your name brand “factory” replacement lamp? US Water Filters replacement lamps are made to the exact same stringent manufacturing protocols. The USWF-140109 is a replacement for VIQUA S810RL ultraviolet lamp used in the VIQUA S8Q-PA and SV8Q-PA systems and the discontinued SSM-37 system. Easy to install and maintain with replacement needed every 12 months. After 9,000 hours the UV light weakens and isn’t strong enough to properly treat your water. Replacing your lamp annually ensures optimal system performance. Safety Note: NEVER look directly at the UV lamp when it is powered on. Follow the instructions carefully to avoid injury to eyes and skin. Includes 2 replacement o-rings.

Ultraviolet light water treatment systems utilize special UV lamps that emit UV light at a wavelength that damages microorganisms cellular function neutralizing the microorganisms DNA and their ability to function and reproduce. Because the microorganisms cannot replicate they cannot infect other organisms they come in contact with. This disinfects the water without the need for chemicals which need to be precisely administered and carefully monitored. Once installed the UV lamp runs 24/7 constantly disinfecting the water that travels through it and only requires minimal annual maintenance to keep running.

Because UV light only travels in a straight line any shadow or obstruction will reduce its efficiency. This means it is important to filter your water before UV treatment to make sure suspended particles like silt and sand are removed. Hardness minerals can also build up on the quartz sleeve which may require cleaning during lamp changes, however if the incoming water is hard enough a water softener is also recommended for pretreatment to reduce this buildup.

Naturally sourced water should be professionally tested and treated before it is used for drinking, bathing, filling swimming and paddling pools, food preparation or cooking. A number of water treatment systems can be used to remove microbiological contaminants that may cause illness. Ultraviolet light disinfection is an effective, reliable, and chemical free water treatment system that can be used to disinfect water from most forms of microbiological contamination.
