The Plumbright Flat Face Straight Isolation Valve (15mm x 1/2 inch) is designed for professional plumbers and DIY enthusiasts who need a reliable shut-off point specifically for monobloc tap flexible connectors. Its primary benefit is providing localized control over water flow, allowing you to perform maintenance or repairs on a single faucet without shutting off the main water supply; however, users should ensure the washer is correctly seated during installation to prevent potential drips at the flat-face connection.

This valve is designed for hot and cold water services, not specifically for high-temperature central heating circuits.
Yes, but you must use a standard pipe insert inside the plastic pipe to ensure the compression fitting maintains its shape.
Yes, it is supplied as a complete unit with the necessary compression hardware.
When the slot on the valve head is perpendicular (at a 90-degree angle) to the direction of the pipe, the water is off.
The valve is rated for standard domestic water pressure; consult your local plumbing codes for specific installation requirements.
No, the flat-face connection relies on the rubber washer in the flexible hose to create the seal, not thread tape.
Tighten the nut by another quarter-turn. Do not overtighten, as this may distort the olive.
Check that the flexible tail washer is seated correctly and is not pinched or cracked.
Check for mineral buildup and apply a gentle, plumber-safe lubricant; do not use pliers on the slot head.
To install, ensure the 15mm pipe is cut cleanly and free from burrs. Slide the nut and olive onto the pipe before inserting the valve body. Tighten the compression nut firmly to ensure a water-tight seal on the copper pipe side. For the 1/2 inch side, attach your flexible tap connector; because this is a flat-faced valve, ensure the rubber washer inside the flexible tail is clean and undamaged. For maintenance, it is recommended to operate the valve once every six months to prevent lime scale buildup. If the valve becomes difficult to turn, avoid using excessive force; apply a small amount of silicone-based lubricant if necessary.
