This old radiator valve started to leak and make a mess on the home owners floor and wall.
A new lockshield valve was fitted, also cleaned up the mess for this really friendly customer.
What is a lockshield vavle?
A lockshield valve is the valve at one end of the radiator that is usually covered with a plastic cap.
Lockshield means that once adjusted, the valve is shielded with the plastic cap.
If the spindle is turned with the spanner it will adjust the flow of water through the radiator.
You would of seen some with numbers on in your own home?
