How do you measure a radiator valve?
Radiator pipe centres is a measure of the distance between the two pipe inlets on your radiator. It is measured from the centre of one of the pipes to the centre of the other.

Do TRV heads fail?
The thermostatic action of TRVs can also fail, so they don’t close down the flow through the radiator when the room gets too warm. If the temperature calibration has slipped out of range, or the thermostatic action has failed completely, the valve will need to be changed.
