Bacteria passes through the UV when it is not on and when power is  restored the homeowner assumes that everything is okay because the UV is  operational again. This may not be the case as bacteria have the  opportunity to replicate on the other side of the operating UV Light.\u003chr\u003e\u003cdiv\u003e  \u003cbr\u003e\u003cdiv align=\"center\"\u003e\n\u003cimg alt=\"Wahl H20 - UV System Risk \u0026amp; Water Contamination\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0646\/5018\/2767\/files\/img_proxy_5946f85c-7230-4a46-81ff-c69fec4c26c3.jpg?v=1754968698\" border=\"0\"\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv align=\"center\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv align=\"center\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cspan style=\"font-weight: bold; font-size: 18pt;\"\u003eFouled Quartz Sleeve \/ Dome\u003c\/span\u003e\u003cbr\u003eWater Quality can have an impact on the ability to see through  the Quartz Sleeve. For simplicity this can be illustrated using a common  light bulb analogy. If you paint a light bulb orange and turn it on,  there is power and the light is on but it will not shine very brightly. The  same analogy applies for a Quartz Sleeve, if Iron (orange staining)  exists in the water there can be a coating of the Quartz Sleeve and  diminish the strength of the UV Ray. The same applies for Water  Hardness (white scaling) and Sulphur (black film). Most UV Systems do not have a device to monitor the strength of the UV Ray and consumers may have an operational system with a fouled sleeve and bacteria passing through the system out into the home's water supply.\u003cbr\u003e\u003cdiv align=\"center\"\u003e\n\u003cimg alt=\"Importance of UV Sleeve Clarity\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0646\/5018\/2767\/files\/img_proxy_327aab78-99f8-4778-bc04-cc2ca8986cff.jpg?v=1754968681\" width=\"1000pxpxpx\" border=\"0\"\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cspan style=\"font-weight: bold; font-size: 18pt;\"\u003eSediment \"Shadowing\"\u003c\/span\u003e\u003cbr\u003eTurbid water (sediment) will also interfere with  the UV Ray as microorganisms can “hide\" in the particles and not be  inactivated inside the chamber.
