Warning from Your Water Supplier
It is a criminal offence to use this tap with a mains water supply drawn directly from the supply pipe. This tap has an outlet on a flexible hose, which if immersed in water, could result in contaminated water being back-drawn into the pipework if the supply pressure dropped.
To prevent contamination and comply with UK plumbing regulations, both hot and cold water supplies to this tap must come from a storage cistern.
If distributing pipes from the storage cistern have other outlets, this tap's outlet must be lower than those other outlets.
If the water from the storage cistern is not suitable for drinking, a separate tap supplied with wholesome water must be provided for drinking purposes.
For more information, contact your Local Water Supplier's Water Regulations Department (see wras.co.uk) or the Water Regulations Advisory Scheme by email (info@wras.co.uk) or telephone: 0333 207 9030.
Installation
Step 1
Feed the pipes through the sink hole and place the tap body.

Step 2
Feed all pipes through the nut, screw onto the threaded pipe, and tighten screws to secure.

Step 3
❗ IMPORTANT: Fit isolation valves for future maintenance.
Connect the hot and cold water connections using the olive and compression nut.

Flexible Connecting Pipes
These pipes can accommodate various installation needs:
- Slight bend
- 90° angle
- Curved round
- Kinks (avoid sharp kinks)
- Twists (avoid excessive twisting)
Visuals demonstrate the flexibility of the connecting pipes, showing examples of a slight bend, a 90° angle, a curved round shape, and warnings against sharp kinks or excessive twists.

Troubleshooting
| Symptom | Cause | Remedy |
|---|---|---|
| Partially closed isolation valve. | Head of water is below the minimum distance required. | Open isolation valve. |
| No flow or low flow rate | 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 residual water tension, the build up of water in the tap body. |
| If water continues to drip, possibly due to the ceramic disc valves | Remove valves 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. | |
| Hose doesn't release/re-turn properly | Hose is blocked/kinked/twisted or snagged on other objects. | Isolate the water supply and check the hose for any blockages or defects. Ensure the area is clear so the hose can't get snagged on other objects. |
| 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. |
General Cleaning
Bristan products are made from premium materials with hand-polished, PVD, EPD, or electroplated finishes.
Clean your tap regularly with warm water, a mild pH-neutral liquid soap, and polish with a soft cloth. Rinse off any residues from soap, toothpaste, shampoos, and shower gels immediately to prevent blemishes.
Avoid household bleaches, harsh cleaners, abrasive cloths, scouring pads, scrub sponges, or steel wool, as they can damage the surface finish.
Some surfaces (e.g., nickel, pewter) may be affected by dyes in cloths. Avoid hanging cloths on spouts.
