The present invention provides a water ingress detection system ( 1 ) suitable for use in indicating the ingress of water ( 12 ) onto a pipe ( 2 ) or vessel inside a casing ( 3 ), from outside. The system ( 1 ) comprises a deflector ( 4 ) secured to the underside ( 7 ) of the pipe ( 2 ) inside the casing ( 3 ) provided theron, a conduit ( 8 ) coupled to the deflector ( 4 ) for leading water ( 12 ) away from the pipe ( 2 ) to a water-sensing indicator device ( 13 ). The indicator device ( 13 ) has a signal output portion ( 17 ) disposed externally of the casing ( 3 ) for signalling the presence of water ( 11 ). The deflector ( 4 ) is formed and arranged for intercepting water ( 12 ) running along the exterior ( 7 ) of the pipe ( 2 ) inside the casing ( 3 ) and diverting it into the conduit ( 8 ), and the conduit ( 8 ) and water-sensing indicator device ( 13 ) can sense substantially only water ( 12 ) intercepted by the deflector ( 4 ). In further respects the present invention provides a pipe or vessel provided with a detection system of the invention, and a method of warning of the ingress of water onto a pipe or a vessel inside a casing from outside said casing, using a detection system of the invention.
