Yes, the Derry Bold kit is specifically designed for standard 15mm pipework.
It is compatible with radiators that feature a 1/2 inch BSP connection, which is the standard size for most modern UK radiators.
While experienced DIYers may be comfortable with the process, it is recommended to use a qualified plumber to prevent leaks and ensure system pressure is maintained.
The lockshield is used to balance the radiator, ensuring the heating system distributes heat effectively throughout your home.
It is not recommended, as paint may interfere with the thermostatic sensor head's ability to detect ambient room temperature.
Check if the pin inside the TRV body is stuck. Remove the head and gently press the pin to ensure it moves freely.
Ensure the connection is tightened correctly or check that sufficient PTFE tape was applied to the threads during installation.
This often indicates the flow is reversed or the system needs balancing via the lockshield valve.
Installation should be performed by a qualified plumber to ensure a leak-free seal. The kit is designed for 15mm diameter copper pipework and uses the industry-standard 1/2 inch BSP thread for connecting to the radiator side.
