The water pressure is measured by two water pressure gauges 7. For this measurement, before reading the water pressure gauge 73 after the main valve 2 is closed, the demand side 4
Close all faucets 8 in . In the illustrated example, the cutting edge of the water pressure gauge 7 is indicated by the indicator 9 and read. Based on the read water pressure gauge output, that is, the water pressure on the demand side 4 at the time of starting the inspection, a comparison water pressure value is set in the comparison water pressure setting device IO. for example.

する。Next, the test time is set in the timer 11 taking into consideration the length of the piping on the demand side. For example, 6 minutes is set as the test time. The indication of the indicator 9 (A1 representing ll'i), the signal representing the comparison water pressure value set to ratio 1 water pressure setting W3: ÷ 10, and the signal representing the elapse of the test time of the timer 11 = or comparator Added to 12. This comparator 12 responds to a signal from the timer 11 indicating the elapse of the test time and
1 is compared with the demand-side water pressure at that time, which represents the indicated value of the indicator 9 at the time of passing, and the comparison water pressure 4+ti, which is set in the comparison water pressure setting device 10, and the ratio is calculated. Based on the result, the presence or absence of water leakage is indicated on the display 13.

。For example, the water JLE on the demand side 4, which was 5 kg/cm2 at the start of the measurement, became 4.98 kg/am after a test time of 6 minutes despite the main tap 2 and all wooden plugs 8 being closed.
If the level is lower than 2, the comparator 12 indicates the presence of water leakage on the indicator 13, for example by lighting a red lamp 14. On the other hand, if the water pressure on the demand side 4 has not decreased to 4.98 kg/cm2 or less after the 6-minute test period has elapsed, the absence of water leakage is indicated on the display 13 and, for example, the green lamp 15 is turned on. This is shown by. If necessary, it is also possible to sound the buzzer 16 when there is a water leak.
