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 sys-
tem pressure increases, water enters the tank’s bladder which expands into the pre-charged air
chamber, keeping system pressure below the relief valve 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: If incoming water pressure is above 40 psi, the pre-charge pressure of the expansion tank should be adjusted to equal the incoming water pres-
sure, not to exceed 80 psi.
