Elbow Action Single lever Wall Mixer with Euro Disc

Quick Answer: The Elbow Action Single lever Wall Mixer with Euro Disc is a wall-mounted mixer tap in which one elbow-operated lever sets both flow and temperature; the title names a Euro disc valve, which most likely means a European-pattern disc cartridge of the kind used in modern single-lever mixers.

The Disc Cartridge Inside a Wall Mixer

Modern single-lever mixers are built around a disc cartridge. Two hard ceramic plates, lapped very flat, sit face to face inside it; one is fixed and the other is moved by the lever. Openings in the plates line up by different amounts as the lever moves, which sets both the volume of water and the share drawn from the hot and cold inlets. Because the plates seal against each other rather than squeezing a rubber washer, a disc valve does not drip from washer wear, although grit or heavy scale can score the faces.

The listing does not explain the words ‘Euro Disc’. They most likely refer to a disc cartridge of the pattern described above, and the exact cartridge should be confirmed at enquiry so that replacements can be sourced later.

Being wall-mounted, this wall mixer with Euro disc takes its hot and cold supplies from pipes concealed in the wall and leaves the sink deck clear, which suits moulded polypropylene sinks that have no tap hole. Wall mixers are commonly connected on a pair of offset (crank) connectors that let the installer correct small differences in the spacing of the wall points. For a spout that can be swung between two bowls, see the Elbow Action Single lever Wall Mixer with Swinging Spout.

Specifications

Care & Handling

• Flush new pipework thoroughly before the mixer is connected; grit carried into a disc cartridge scores the ceramic faces.
• Where the water is hard, descale the aerator regularly and expect to service the cartridge sooner.
• Keep a note of the cartridge type so that a matching replacement can be ordered when it is needed.
• Clean the body with mild detergent and a soft cloth.

Applications

• Moulded polypropylene lab sinks without tap holes, where the fitting must come from the wall.
• Handwash stations in biology, microbiology and pharmacy labs that have a hot-water supply.
• Refurbishments that replace two separate wall taps with one hands-free mixer.
• Wash-up sinks where warm water helps to shift fats, waxes and ointment bases from glassware.

Why Choose LabEquip

Contractors fitting wall-plumbed lab sinks and institutions standardising on disc-valve mixers are the usual buyers. LabEquip includes this mixer in General Lab Products; ask about the cartridge and the wall-point spacing on the contact page.

Frequently Asked Questions

What is a Euro disc valve?

The listing does not define it. The term most likely means a European-pattern disc cartridge, in which two flat ceramic plates slide over each other to control flow and mixing. Ask for the cartridge details when ordering so that spares can be matched later.

Why do disc cartridges drip less than washer taps?

A washer tap seals by squeezing rubber onto a seat, and the rubber wears and hardens. Ceramic discs seal face to face and wear very slowly, so drips are less common unless grit or scale damages the discs.

Does a wall mixer need a tap hole in the sink?

No. The mixer is fixed to the wall and fed from pipes behind it, so the sink deck stays undrilled. This suits moulded plastic sinks and wall-hung basins.

What are crank connectors on a wall mixer?

They are short offset fittings screwed into the wall points. Turning them moves the mixer’s inlets closer together or further apart, so small errors in the spacing of the wall pipes can be corrected during fitting.

Can the cartridge be replaced without removing the mixer?

On most single-lever mixers the lever and cover are taken off and the cartridge is unscrewed from the body while the mixer stays on the wall. Shut off both supplies first.

Is this mixer suitable for hard water areas?

Yes, with care. Hard water leaves scale on the aerator and cartridge, so descale the outlet regularly and expect the cartridge to need servicing more often than in soft-water areas.
