Extended Product Information

FAQs

Can I use this with 15mm pipework?

No, this specific model is designed for 8mm pipework. Using it on 15mm pipes without professional reduction adapters will cause fitment issues.

Does this set include both valves for one radiator?

Yes, it includes one thermostatic valve head and one matching lockshield valve, which is the complete set required for one radiator.

What does the 1/2 BSP connection mean?

This is the standard thread size used for the connection point where the valve attaches to the radiator itself.

Can the thermostatic head be replaced if damaged?

Yes, the head can be unscrewed and replaced if necessary, provided you find a compatible replacement with the same connection thread.

Is the black finish durable?

The finish is designed for standard residential environments. To maintain it, avoid abrasive cleaners and harsh chemicals.

Troubleshooting

Radiator remains cold despite valve being turned up

Ensure the pin inside the valve body is not stuck. Remove the thermostatic head and gently press the metal pin to ensure it moves freely.

Visible water leak at the pipe connection

Check that the compression fitting is fully tightened. If the leak persists, re-apply PTFE tape to the threads and ensure the pipe is cut cleanly.

Valve feels loose on the radiator body

Verify that the valve is fully tightened onto the radiator tail piece and ensure the nut is securely seated.

Setup, Compatibility & Care

This valve set features a 1/2 BSP connection, which is the industry standard for most UK radiators. Installation should be carried out by a competent person or professional plumber to ensure a watertight seal. When installing, ensure that the thermostatic head is positioned in an area where it can sense air circulation, rather than behind heavy curtains or furniture, to prevent inaccurate temperature readings. For maintenance, wipe the valve body with a soft, dry cloth to preserve the black finish; avoid using abrasive chemicals or metal scourers that could damage the paint.
