Hard water
detected in the
outlet.
Probable leakage between inlet and
outlet or between the valve and tank
seal.
A Damage on the inlet internals

o-ring ( 1 ) and ( 2 ) or on the inlet
piston. Dismount the valve and
visually check these items.
Replace them if they are
damaged.
B The rise pipe o-ring may be
damaged, disconnect the valve
from the tank and check the

o-ring status.
High pressure drop is causing the
opening of the automatic bypass.
If mixing is not desired replace the
automatic bypass with a manual
bypass model.
Inlet piston is out of position causing
bypass between inlet and outlet.
In that case a leakage on the drain
should also be observed. Check for
problems on the pilot circuit otherwise
check if the pilot pressure is in
compliance with the valve
specifications. For twin pilot valves,
the screen inside the manifold may be
plugged by dirt causing pressure drop
on the pilot circuit. Remove and clean
it.
Bypass valve not closed. Ensure that the bypass valve is closed.
No brine draw.
Low water pressure at the inlet.
Close the outlet of the valve, check that
the pressure gauge shows a pressure
of at least 2 bar. If it is lower, the
pressure is insufficient. If the pressure
is higher than 2 bar, check the
mechanical filter which is installed
before the injector is plugged by dirt.
Remove it and clean.
Screen on the manifold is plugged by
dirt. Remove manifold and screen and
clean thoroughly.
Plugged injector.
Remove injector, thoroughly clean the
holes in the injector and remount it.
Problems in salt/brine tank.
Thoroughly check the connection
assembly to the brine tank:
A Check that there are no
obstructions in the connection
system.
B Check that there is a flow when the
float is in lower position.
C Check that there is no formation of
a salt bridge in the brine tank.
D Check that all components of the
brine valve operate efficiently.
