V230
Hard water
detected in the
outlet
Probable leakage between
inlet and outlet or on valve/
tank seal
High pressure drop is
causing the opening of the
by-pass
Inlet piston is out of
positison causing by-pass
between inlet and outlet
Bypass valve not closed
No brine draw Low water pressure at the
inlet
Screen on the manifold is
plugged by dirt
Plugged injector
Problems in salt/brine tank
A) Damage on the inlet internals - o-ring 1 , 2 or the
inlet piston may be damaged. Dismount the valve
visually check and eventually replace them if they
are damaged
B) The rise pipe o-ring may be damaged, disconnect
the valve form the tank and check the o-ring status.
If mixing is not desired replace the automatic by-pass
with a manual by-pass model.
In that case a leakage on the drain should be also
observed. Check for problems on the pilot circuit
otherwise. Check if the pilot pressure is 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.
Ensure that the bypass valve is closed.
Close the outlet of the valve; check that the pressure
gauge shows a pressure of at least 2 bars. If it is lower,
the pressure is insufficient. If the pressure is higher
than 2 bar, check whether the mechanical filter which is
installed before the injector is plugged by dirt. Remove it
and clean.
Remove manifold, remove screen and clean thoroughly.
Remove injector, thoroughly clean the holes in the
injector and remount it
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 without any leaks from any
fittings.
