Full details
The Plumbright Straight Isolating Valve (15mm x 1/2 inch) is an essential tool for homeowners and DIY enthusiasts looking to manage their plumbing system with greater control. It allows you to isolate individual water outlets for maintenance or repair without the need to shut off the main water supply to your entire home, though professional installation is recommended if you are uncomfortable working with pressurized water lines.

FAQs
Is this valve suitable for central heating systems?
Yes, this valve can be used on heating systems, but ensure that the temperature and pressure ratings align with your specific system requirements.
Do I need PTFE tape for this installation?
Compression fittings generally do not require PTFE tape as they rely on the compression olive for the seal; however, a small amount on the threads can sometimes provide extra peace of mind.
Can I install this on plastic piping?
Yes, but ensure you use the correct pipe insert (stiffener) inside the plastic pipe to prevent it from collapsing when the nut is tightened.
Which way is 'off'?
When the lever is perpendicular (at a 90-degree angle) to the pipe, the water is turned off. When it is parallel to the pipe, the water is on.
What is the maximum pressure rating?
The valve is rated for standard domestic water supply pressures; avoid using it in high-pressure commercial pump systems.
Troubleshooting
The valve is leaking from the nut connection
Tighten the compression nut slightly with an adjustable wrench, or ensure the olive is not damaged and properly seated.
The lever is difficult to turn
Apply a small amount of silicone-based plumber's grease to the stem or cycle the valve multiple times to break up minor limescale buildup.
Water continues to flow when in the 'off' position
The internal seal may be faulty; ensure the valve is fully turned to the stop position, otherwise the unit may need replacement.
Pros and Cons
Pros
- Prevents the need to drain the entire home plumbing system
- Standard dimensions ensure broad compatibility
- Simple manual operation
- Compact design fits into tight spaces
Cons
- Requires cutting into existing pipework to install
- May require PTFE tape for a watertight seal
- Not suitable for high-pressure industrial applications
Setup, Compatibility & Care
To install this valve, first ensure the main water supply is turned off. Use a pipe cutter to remove a section of the 15mm pipe, then fit the valve using appropriate compression fittings. Ensure the olive is seated correctly before tightening the nut to prevent leaks.
Compatibility: This valve is designed for 15mm copper or plastic piping and standard 1/2 inch tap connectors.
Care: Periodically test the lever by turning it to the 'off' position and back to 'on' once every six months. This prevents mineral deposits from causing the valve to seize over time.
