Fault 

Solution

Showering temperature is not hot enough.

Ensure the hot water supply is at a
constant temperature above 60˚C.
Check for air locks in the pipework.
Thermostatic cartridge movement limited
due to lime scale build up

The water goes cold during showering.

Insufficient stored hot water. 
When used with a combi boiler confirm
that the boiler is still firing.
Adjust the boiler to a minimum setting of
65˚C which may not necessarily be the
best flow rate.

When the water is set at cold, the
showering temperature is too hot.

The hot and cold supply connections have
been made in reverse.
Thermostatic cartridge movement limited
due to lime scale build up

The maximum showering temperature is
too hot or when set to hot water runs to
cold.

Check the commissioned maximum
temperature of the shower valve.
Check the connections to the valve have
not been made in reverse.
Thermostatic cartridge movement limited
due to lime scale build up

The flow of water from the shower valve is
low.

Check the filters are clean and the supply
pressure is above 0.2 bar.

No flow of water

Ensure the valve has not fail-safed and
check that there is hot and cold water flow
to the valve.
Ensure the check valves are not closed.

Shower is stiff to operate

Build-up of limescale on flow control
cartridge   - service and de-scale

Passing/dripping from outlet

Service flow control cartridge.
