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.

Pre-Filter Required

The most suitable replacement for this is the
