It is strongly recommended (by all UV manufacturers) for maximum efficiency of your UV Sterilization, that you pre-filter your water with a 5 Micron sediment cartridge.
Do not connect plastic pipe or tubing directly to the UV system because the UV light will break down plastic over time. The best way to make the connection is with Dielectric Unions that allow for a connection from stainless steel to copper, that will not corrode.
Ultraviolet light is split into several different ranges: (near the visible light range) UV-A, UV-B, UV-C, Vacuum-UV (near the x-ray range). The UV-B range is what causes sunburn on humans. UV water purifiers use the UV-C range because of its germicidal abilities. In this range the light light will break molecular bonds in the DNA of viruses and bacteria, rendering them unable to reproduce and effectively killing them.
