Product Information
Full details
The JG Speedfit Service Valve (15mm) is designed for plumbers and DIY enthusiasts needing a reliable way to control water flow to individual taps, particularly for maintenance or emergency repairs. Its primary benefit is the tool-free, push-fit installation and demounting, significantly speeding up plumbing tasks, especially in tight spaces. A key caveat is its unsuitability for central heating systems. This valve offers a secure, leak-proof connection for hot and cold water services when used with plastic or copper pipes, featuring a 1/4 turn screw for precise flow control.

Troubleshooting
Valve is leaking after installation

Verify the 1/4 turn screw is rotated fully clockwise. Check for any debris obstructing the valve mechanism. Ensure the valve is correctly installed on the pipe.
Difficulty in demounting the pipe
Ensure you are pushing the blue collet firmly towards the fitting body. If stuck, try gently twisting the pipe while applying pressure to the collet.
Valve not sealing properly
