Planning
- Ensure an appropriate piping design (sizing etc). This will eliminate issues arising from flow, pressure and water hammering.
- Where appropriate install necessary inline filters, water hammering arrestors and water pressure reducing valves (recommended pressure 2 to 4 bar). This will minimise future maintenance.
- Install an angle valve to enable ease of future maintenance.
Tempered Water
- An appropriate thermostatic mixing valve (TMV3) should be installed to ensure a safe regulated water temperature. These are available from SPL: BEN-TMV
Components

Faucet Installation Steps
- Install 1/2" angle valve, stop cock or equivalent.
- Flush lines thoroughly to pass any debris.
- Cut hole in mounting surface (if required): Ø 25mm min - Ø 35mm max.
- Pass threaded stem through top of mounting surface (refer to Fig 2).
- On the underside of the mounting surface fit the gasket and flanged nut. Tighten (refer to Fig 3).
- Connect stainless flex (not provided) (refer to Fig 4).
- Connect flex to 1/2" angle valve (refer to Fig 5).
- Turn on water supply and check all connections. Activate the tap several times to stabilise flow time (refer to Fig 6).
NOTE: Seal with silicon if required to create waterproof seal between the tap and mounting surface.
NOTE: Within normal water pressure ranges, the tap will self-regulate to flow for 8-12 seconds once the button is pushed.
Important
The installer is required to ensure the waterproof seal is appropriate between the tap and the mounting surface. If in doubt regarding the seal, install with a suitable silicon. In addition, the recessing area must be waterproof and have a drainage point, to eliminate potential water ingress.
Troubleshooting
Symptom | Possible Cause | Corrective Action |
---|---|---|
Water dribbles or trickles | a. Debris or hard water buildup in cartridge | a. Remove cartridge and clean internals including seals and time delay cups with a soft cloth & pin on internal groove. b. Replace if damaged (cartridge). |
Water flows too long or continual flow | a. Build up of foreign material or worn seal/seat b. Incorrect time delay cup installed | a. Remove cartridge and clean as per above. Check lip seal and seat are in good condition. Replace cartridge if damaged. b. Install different time delay cup 4/6 sec, 8/12sec, 12/16sec. |
Water doesn't flow long enough | a. Pressure too low? b. Aerator blocked? c. Incorrect time delay cup installed | a. Check pressure; 2 - 4bar recommended. b. Remove aerator and clean. c. Install different time delay cup as above. |
Water temperature too cold/hot (if tempered) | a. Source of hot/cold water and piping arrangement b. Pressure of hot water source c. Incorrect setting on TMV | a. Check source and pressure of hot and cold water. b. Eg. continuous water heater pressure. Balance the hot and cold pressure. c. Adjust mixed temperature on TMV. |
Maintenance
This product due to its design may need some maintenance. The regularity of this will depend on its usage and the water type. If in a hard water area maintenance may be required more often.
To maintain good working order, it is recommended to clean out the white plastic cup inside the tap/mixer, specifically the fine internal groove.
- To do this first turn off water supply.
- Remove handle/valve using a spanner.
- The valve will then pull from the tap/mixer.
- The white plastic cup may come away with the valve, if not simply remove it by pulling it from the body.
- Once removed, clean out cup and run down the groove using a pin to clear out dirt.
- When thoroughly cleaned, replace cup, valve and tighten.
- Clean faucet regularly using soapy water and a soft cloth or wet sponge.
- DO NOT clean faucet with any abrasive material or chlorine/acid-based cleaning product. This may damage the finishing of the faucet.
- DO NOT use grease on the internal cartridge.
