WRAS-approved filtered water in an elegant Brushed Brass tap
The Clearwater Mariner MAL10BB combines normal hot and cold water with a separate filtered cold-water supply in one refined U-spout design. Its Brushed Brass PVD finish brings warmth to the kitchen, while WRAS approval provides clear reassurance that the exact model has been independently assessed for use with UK water supplies.

A simpler way to add filtered water at the sink
The right-hand lever mixes ordinary domestic hot and cold water. Filtered cold water is dispensed using the subtly hidden press-control on the left, keeping the Mariner’s profile exceptionally clean.
- Single mixer lever for normal hot and cold water
- Concealed press-control for filtered cold water
- Dedicated filtered-water route prevents internal mixing
- Single-hole installation avoids a separate drinking-water tap
Normal mixer water and filtered water remain distinct
The Mariner brings three water supplies into one tap without sending filtered water through the normal mixer route. Its discreet controls make the operation obvious while preserving the minimalist design.
Hot water
Mixed using the main right-hand lever.
Cold water
Mixed using the same right-hand lever.
Filtered water
Operated by the concealed left press-control.
Minimalist lines without sacrificing everyday practicality
The softly squared U-spout gives the Mariner a distinctive architectural shape, while the Brushed Brass PVD surface adds a warm, premium accent. The spout rotates through 360° for flexible positioning over larger or multi-bowl sinks.
- Brushed Brass PVD decorative finish
- Modern U-shaped spout with a subtle 12° outlet angle
- 360° swivel movement
- Non-pull-out construction with ceramic valve technology
WRAS approved for added confidence in UK installations
Clearwater identifies the Mariner MAL10BB as WRAS approved. This means the product has been independently assessed against the relevant requirements for water fittings used with UK public water supplies—not simply given an unverified marketing badge.

Frequently asked questions
Is the Clearwater Mariner MAL10BB WRAS approved?
Yes. Clearwater’s current manufacturer information identifies the Mariner MAL10BB as WRAS approved. This provides independent product approval, although the tap must still be installed correctly and in accordance with the supplied instructions.
How is the filtered water operated?
Filtered cold water is dispensed using the concealed press-control on the left side of the tap. The normal hot and cold mixer is controlled by the single lever on the right.
Does filtered water mix with ordinary tap water?
No. The filtered supply follows a dedicated internal route and remains separate from normal hot and cold mixer water.
Does the Mariner include a filter?
Yes. The current MAL10BB package includes the F6C1UF ultrafiltration cartridge, connectors and Pure FlowPro digital usage monitor.
Is the Mariner a pull-out tap?
No. This MAL10BB model has a fixed non-pull-out U-spout that swivels through 360°.
What pressure does the Mariner require?
The official instructions specify an operating range of 0.5–5 bar.
What is the maximum worktop thickness?
The dimensional drawing specifies a maximum mounting-surface thickness of 40 mm and a 35 mm tap hole.
How often should the filter be replaced?
Clearwater recommends replacement at around six months for normal household use. The cartridge must be changed at least every 12 months, and sooner if its capacity is reached or performance changes.
Can it work with a water softener or reverse-osmosis system?
The manufacturer permits compatible alternative filtration and softening arrangements, provided the pressure and connection requirements are met and the filtered line is not run above 4 litres per minute. Ask Regal Flow to check the proposed layout before ordering.
Need help checking compatibility?
Ask Regal Flow about water pressure, worktop thickness, filter replacement, sink clearance or installation planning before you order.
