Product Information

Full details

The Plumbright Full Flow 15mm Angled Isolation Valve (Q70126) is designed for homeowners and professional plumbers who require a reliable, high-performance method for controlling water supply to specific fixtures. Its primary benefit is the full-bore design, which allows for maximum water pressure even when partially open, ensuring efficiency in your plumbing system; however, users should note that it requires a flathead screwdriver for operation rather than a manual handle, which may be less convenient for frequent adjustments.

FAQs

Does this valve restrict water flow?

No, it features a full-flow design that ensures there is no significant reduction in water pressure.

Can I use this with plastic pipe?

Yes, it is compatible with 15mm plastic pipe, provided you use the correct pipe inserts to ensure a solid connection.

Is this suitable for hot and cold water?

Yes, the valve is constructed to handle standard domestic hot and cold water supply systems.

How do I know if the valve is open or closed?

When the slot is aligned with the direction of the pipe, the valve is open. When it is turned 90 degrees (perpendicular to the pipe), it is closed.

What tools do I need for installation?

You will need a pair of adjustable wrenches for the compression fittings and a pipe cutter or hacksaw to prepare your 15mm piping.

Troubleshooting

Slight weeping from the compression joint

Tighten the compression nut by a quarter-turn using a wrench; if the leak persists, check that the pipe olive is seated correctly and undamaged.

Valve slot is difficult to turn

Ensure you are using the correct size flathead screwdriver and apply a small amount of plumber-grade silicone lubricant to the spindle.

Water continues to flow when valve is turned off

Ensure the valve has been rotated a full 90 degrees until the slot is perpendicular to the pipe flow.

Pros and Cons

Pros

  • Maintains excellent water flow rate due to full-bore design
  • Compact angled shape fits easily in tight spaces behind pedestals
  • Reliable shut-off mechanism prevents drips and leaks
  • Suitable for both professional contractors and DIY enthusiasts

Cons

  • Requires a tool (screwdriver) for operation
  • Not suitable for applications requiring frequent daily manual turning
  • Limited to 15mm pipe diameter systems

Setup, Compatibility & Care

To install, ensure your water supply is completely drained from the section of the pipe where the valve will be placed. The valve is compatible with standard 15mm rigid copper pipe or appropriate 15mm plastic piping systems (when used with correct inserts). Ensure that the compression nuts are tightened firmly onto the pipe olive to create a watertight seal. For care, keep the slot on the valve head free of debris. If the valve becomes stiff after several years, do not force it; apply a small amount of silicone-based lubricant to the spindle to assist with smooth rotation.
