Troubleshooting
Valve
Symptom
Likely cause
Action/Remedy
Outlet temperature too cold
• No hot water reaching valve
• Filter block
• If the fault has been present
since the valve was installed it
is possible that the inlets were
installed incorrectly
• The water supply will be colder
in winter months due to outside
temperature
• Check the water supply for any
blockages
•
Remove filters and clean
• Check installation-Hot on the left /cold
on the right
• It may be necessary to adjust the hot
supply. i.e. increase the hot water
temperature setting on boiler
Outlet temperature too hot
• No cold water reaching valve
• Filter block
• If the fault has been present

• The water supply will be hotter in
summer months due to outside
temperature
• Check the water supply for any
blockages
•

Only hot or cold water from
valve outlet
• Possible that the inlets have been
installed the incorrect way around
• If only cold water is coming out of
the mixer it is possible there is a
cartridge fault
• Filters blocked
• Remove the thermostatic cartridge and
service.
• Remove the temperature handle by
removing the end cap and center
retaining screw turn the flow of water
on fully and turn the cartridge spindle
anti -clockwise to increase the water
temperature and clockwise to decrease
the water temperature
Poor Flow Rate
•
Insufficient water pressure
• Filters partially blocked
• Flow valve not fully opening
• The required minimum water pressure is
0.5bar (5Mpa)
•
Remove filter and clean
• Remove and check the condition of the
flow valve
Water leaking from shower head
when the valve is turned off/
closed
• This can be normal for a short
period time after the shower has
been used
• Check that the pressures do
not exceed of that stated for the
product
• Flow valve leaking
• N/A
• If pressures are too high adjust as
necessary, refer to technical data
• Remove and check the condition of the
flow valv
Water leaking from shower valve
/controls
•
Leaking from flow valve
• Leaking from thermostatic
cartridge
• Check that the pressures do not
exceed that stated for the product
• Remove and check the condition of the
flow valve.
• Remove and check the condition of the
thermostatic cartridge.
• Check that the pressures do not exceed
that stated. If pressures are too high
adjust as necessary. Refer to technical
data
