Application
Designed for installation on potable water lines between the
backflow preventer or pressure reducing valve and the water
heater to protect against water thermal expansion. When
system pressure increases, water enters the tank’s polypro-
pylene lined water chamber which expands a diaphragm into
a pre-charged air chamber, keeping system pressure below
the relief valve setting.
