Troubleshooting

Symptom

Cause(s)

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.

Head of water is below the minimum distance required.

Check the site has the required working  

pressures according to the specification.

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 or 

hoses.

Flush through pipework to ensure removal of  

debris and any airlocks.

Water supply failure

Investigate water supply. Check your plumbing 

and heating systems for any faults.

Hose is leaking due to aging/damaged O-Rings or  

Anti-Friction seals

Call Customer Services for replacement seals

Water 

dripping from 

taps

This is normal for a short time after using the taps.

This is caused by residual water tension,  

the build up of water in the tap body.

If water continues to drip, 

possibly due to the ceramic disc valves/cartridge

Remove valves/cartridge and clean, refer to  

'Maintenance' section before starting any  

maintenance.

Taps do not 

turn on

Closed isolation valve.

Open isolation valve.

Mains water supply turned off.

Turn on mains water supply.

Handset  

Pressure 

Changes

 Site water pressure is too high for the working  

pressures listed on the specification.

Install a Pressure Reducing Valve in order to 

achieve working levels of pressure.

Your fitting has a high quality finish and should be treated with care to preserve the visible surfaces.

All surfaces will wear if not cleaned correctly, the only safe way to clean your mixer tap is to wipe with a  

soft damp cloth. Stains can be removed using washing up liquid. All bath cleaning powders and liquids  

will damage the surface of your fitting, even the non-scratch cleaners.

Note:

   Never use abrasive detergents or disinfectants or those containing alcohol,  

 

hydrochloric acid or phosphoric acid.
