COMPONENT
1. EWS Series. Inhibits scale formation and protects the
entire home and family from the health side-eects
and corrosiveness of chlorine, chloramine, VOCs,
THMs, and much more.
2. Heater Guard. Protects water heaters at the inlet.
Combined with an EWS system, it is the perfect
application for healthy, hassle-free water to the
whole home.
3. Softener. Will inhibit scale formation, however, the
water becomes aggressive and may have long-term
corrosive eects on your water heater.

3 BEST WAYS TO PROTECT YOUR HEATER

Under no circumstances does
the EWS Heater Guard change
or alter the proper application
and/or routine maintenance
required or recommended by the
manufacturer of any product.
‡The lter gauge is based
on a pressure dierential. It
can only be observed while
water is owing through the
Heater Guard and will only
move when lter cartridge has
been prematurely clogged or
restricted. The gauge is only a
precaution to prevent problems.
