Plaintiff’s assertion

On October 13, 2018, the Defendant performed the fire-fighting work (hereinafter “instant work”) at the Plaintiff’s “E Branch” site located in Seocheon-gu, Seocheon-gu, Seocheon-gu, Seoul.

However, even though the work should be done after cutting the valves and removing all water being drained in the pipes before the work, the Defendant did not check whether water being drained in the pipes was removed, and the Defendant’s negligence caused water leakage when the Defendant replaces the 5th hedging.

The plaintiff is expected to compensate for damages to the damaged company at the plaintiff's expense, replace the designated agencies, electrical construction, fire fighting and repair works, or repair works for the damaged company due to the above leakages, and the damage equivalent to the cost was suffered.

Therefore, the defendant is liable to compensate the plaintiff for the above damages amounting to 54,440,00 won.

Judgment

In the course of the Defendant’s work in this case, water spouts from pipes when replacing the 5th heading, and the fact that water spouts have occurred to the neighboring stores of the work site in this case is not recognized in full view of the purport of the entire pleadings or there is no dispute between the parties, as stated in subparagraphs 9-1 and 2.

However, in full view of the purport of the argument in Gap evidence No. 13, prior to the execution of the instant work, the defendant carried out the work of a building manager in the building pest control room to lock the valves and remove water in the pipe, and then delivered it to the defendant, and the fact that water leakage has not occurred until the defendant replaces four sprinklers.

According to these facts, the occurrence of water leakage in this case is due to the failure to remove water from the pipe of this case.
