In some situations, a blending valve option (3/4-inch or 1-inch) may
be desired. The amount of hardness blended back into the water
line is determined by the hardness of the incoming water and the
setting of the blending valve. Where extremely hard water is
present, the blending valve may only need to be “cracked” open.
Where the incoming water has relatively low levels of hardness, the
blending valve will need to be opened further.
The blending valve is located between the input and output
connections on the top of the bypass valve (Figure 18). It is
adjusted by placing a flat blade screwdriver in the slot provided and
turning clockwise to open. Total movement of the blending valve
from full closed to full open is 1/4 revolution.
Precise setting of the blending valve will require “trial and error”
testing. The initial setting should be conservative. Because of the
blending valve's ease of access and adjustment, the end user can
increase or decrease the setting according to their preference over a period of time.
Use of the Blending Valve
Use of the blending valve is not recommended where objectionable concentrations of ferrous iron or sediment are
present. Because the blending valve is mixing “raw” water with softened, any ferrous iron or sediment in the “raw”
water will also be blended and reintroduced into the softened water line.
Note:
If your system is installed for barium and/or radium reduction, the blending valve must remain in the fully
closed position at all times.
