1. An apparatus comprising:
a first tube segment having a first exterior surface and a first length;
a sensor cable; and
a first wrapping, wherein:
the sensor cable is disposed along the first exterior surface and runs the first length of the first tube segment;
the first wrapping forces the sensor cable against the first exterior surface with a first gap between the first exterior surface and the first wrapping such that liquid entering the first gap moves within the first gap and contacts the sensor cable; and
liquid contacting the sensor cable changes an electrical property of the sensor cable.
