Vibration is one of the major causes of fittings or fixings working loose and giving rise tc leaks. Other items contribute, such as poor fitting, or overheating, which causes seals first to bake and then crack.

• In the case of liquids: puddles will form

• In the case of gases: noise, smell or bubbles when tested with soapy water.
