Abstract (en)
[origin: EP3557154A1] A pipe abnormality detection system (100) is provided with: a pipe (110) which includes a flow inlet (111) into which water in a bathtub (200) flows, and a flow outlet (112) through which water flows out to the bathtub (200); a pump (121) which circulates the water between the pipe (110) and the bathtub (200); a pressure detection sensor (122) which detects the internal pressure of the pipe (110); and an output device (150) which outputs a signal indicating that an abnormality of the pipe (110) is detected when at least one among a difference between the pressure detected by the pressure detection sensor (122) when the pump (121) is stopped and the pressure detected by the pressure detection sensor (122) when the pump (121) is operating, and a rate of change in the difference relative to a rotational frequency of the pump (121), deviates from a predetermined range.
