Construction method for preventing water supply branch tubes concealed laid in houses from civil damage

The invention discloses a construction method for preventing water supply branch tubes concealed laid in houses from civil damage. The method comprises steps as follows: establishing a concealed laying scheme for the water supply branch pipes in the houses, and performing concealed laying construction; formulating a water supply and pressure test scheme, and selecting a pressurizing point and a pressure observing position; supplying water for pressure test and pressure relief; numbering pressure gauges reserved in a pipe shaft, and setting a sign and disclosure; performing pressure observation and the like. The construction method has the advantages as follows: the operation is simple and easy to implement, the observation effect is relatively visual, and leaking points of the constructed water supply branch pipes damaged during civil construction are easily found, so that timely repair is facilitated; the leaking points can be found before laying of a mortar levelling layer and floor tiles is completed, inco
