"Does a UV system require any chemicals or anything else that I have to add??"
Most manufacturers recommend that you use a 5 micron (or smaller) sediment
filter before a UV unit. This is required because large particles provide
a haven for microorganisms that you are trying to destroy. Depending on the
turbidity of the water, multiple sediment filters
may also be required before the UV system. If color or suspended particles
are present, the transmission quality of any UV light is diminished. Where this is a problem, a
quality carbon filter may be needed after the sediment filter and before the UV unit.
"Is there anything I should do before installing an ultraviolet filter system??"
Before installing any UV (brand) unit, it's a good idea to start with a
clean system (water lines, water heater, etc.). Disinfect the entire downstream
system with chlorine or other disinfectant that is safe for piping and humans.
"How long does the UV bulb itself last?"
American Plumber recommends replacing the bulb once every 10 to 12 months. The bulb will last a lot longer then that, however its capacity for
neutralizing microbes diminishes after that length of time.
"I just installed a new filter cartridge and my water is cloudy/white?"
After you install a new filter (this is the case with any/all brands of filter cartridges) you should run it
for a few minutes. Generally cloudy or white water indicates air in the line and this is natural and normal with a
replacement of a cartridge. Air will enter in the housing, lines and cartridge.
Just run the water for a few minutes and the cloudy conditions will go away (unless you have VERY cold water in
which case it is the oxygen in the water that could be making the water look cloudy). It is always a good idea
to run the water free flowing for a few minutes after installing any brand or type of new filter cartridge.
