Troubleshooting
Symptom Cause Remedy
No flow or low
flow rate
partially closed isolation valve. Open isolation valve.
Instantaneous water heater
cycles on and off as flow rate or
pressure is too low.
Increase water flow rate or
pressure through system to
meet required minimum working
pressure of tap.
Head of water is below the
minimum distance required.
Refer to 'Specifications' on page
4.
Hot or cold water being drawn
off elsewhere causing pressure
changes or instantaneous boiler
temperature changes.
Do not use other water outlets
when using the taps.
Airlock or partial blockage in the
supply pipework.
Flush through pipework to
ensure removal of debris and
any airlocks.
Water dripping
from taps
This is normal for a short time
after using the taps.
This is caused by capilary action,
the build up of water in the tap
body.
If water continues to drip,
possible build up of debris/
limescale in ceramic disc valves.
Remove valves and clean, refer
to 'Maintenance' section on page
12 before removing the valve.
Taps do not
turn on
Closed isolation valve. Open isolation valve.
Water supplies to the tap turned
