Problem: Combination Softener unit appear to be causing a high pressure drop in home water system.
1. Pressure drop may be due other factors. • Confirm pressure loss is due to the unit, and
not the result of distribution or well pump problem.
• Confirm pressure loss is due to unit by
checking flow while in BYPASS mode.
• Check that flow demand is not exceeding rated
flow rate of Combination Softener unit. These units
are supplied with a SERVICE LINE FLOW
CONTROL to ensure maximum effectiveness is
maintained. Attempting to exceed this flow control
rating will result in a pressure drop. Combination
Softener unit should be increased in size to
compensate for larger demand.
NOTE: Do not remove this FLOW CONTROL
from valve outlet. It will likely result in a
decrease in Combination Softener unit
performance.
2. Pressure loss may be due to fouling from • See troubleshooting notes above on dealing with

• Install multi-media filter or 5 micron cartridge filter
ahead of the unit to remove Silt and Turbidity.

• Check to see that BYPASS valve is not partially

• Check that pipelines after the unit are not lined
with organics that are slowly being stripped away.
Lines may require flushing.
• If all equipment and distribution sources of problem
have been eliminated, consult your water treatment
dealer, who may try to “polish” the remaining colour
after the the unit with an ACTIVATED CARBON
