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 polypropylene lined water chamber which
expands a diaphragm into a pre-charged air chamber, keeping system pressure below
the relief vale setting.
Water pressure reducing valve (Model NR3)
Temperature & pressure relief valve (Model TP1100A)

Local codes shall govern installation requirements. Unless otherwise specified, the assembly shall be mounted on the cold water supply and at least 18”
from the cold water inlet to the heater.
NOTE: Pre-charge should be adjusted to match incoming water pressure (adjust pre-charge with no water pressure in tank). Not to exceed 80psi.
