Rainwater harbours bacteria of all types but in some cases, much more harmful bacteria may be present in the tank. E-Coli is a common bacterium in tank water and is due mostly to Frogs in and around your tanks\/catchment. Ultraviolet sanitation works by breaking down the cell wall of a micro-organism allowing oxidation to occur which in turn prevents the bacteria from multiplying until it is finally eradicated. Ultraviolet filtration is a chemical-free solution to water sanitation creating no by-products in the water.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"margin: 0px 0px 12px; padding: 5px 0px; outline: none; border: none; text-decoration: none; animation: scale 0.7s ease-in-out; line-height: 24px; font-size: 13px; font-family: Roboto; color: #000000; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px;\"\u003e\u003cspan style=\"margin: 0px; padding: 0px; outline: currentcolor none medium; text-decoration: none; animation: 0.7s ease-in-out 0s 1 normal none running scale; display: block; font-size: 12pt; font-family: verdana, geneva, sans-serif;\"\u003e​We recommend adding the optional UV Thermal Relief Valve for any situation where the UV system is installed and water is not continuously running through the system.
