In the Case of Water Leakage or Drainage Overflow

If the location of the leak has been identified, close the nearby shutoff valve or main valve to stop the flow of water. If the location of the shutoff valve is unknown, do not attempt unreasonable action; contact a specialized contractor promptly.

• Protect the area around the leak with towels or curing sheets to slow water penetration to the floor below
• If there is concern about an impact on electrical systems, turn off the breaker for the relevant area only when safety can be ensured. Avoid operating electrical equipment with wet hands or from flooded areas, and if there is any danger, contact a specialized contractor or the management company

Checking the locations of shutoff valves and main valves in the building during normal times will make the initial response smoother in an emergency.

In the Case of Pump Failure or Water Outage

If a water outage or overflow occurs due to failure of a water supply pump or drainage pump, the operations that the building manager can perform are limited. The most important action is to check the alarm details on the alarm panel and the indications on the control panel, and accurately communicate that situation to a specialized contractor. Unnecessary operation of power to the pump may further damage the equipment, so priority should be given to recording the situation and promptly contacting a contractor.

Notification and Records

Promptly make emergency announcements to residents and users in the affected area, and at the same time record the on-site situation with photos or videos. These records may be useful later when communicating with the contractor to identify the cause, and as documentation for insurance procedures when insurance coverage applies.

Emergency Measures and Clearing Blockages

In the case of water leakage, the contractor stops the water and carries out temporary repair of the damaged area to prevent the spread of secondary damage. For drainage blockages and overflows, a high-pressure washer or a drain cleaning cable machine (wire-type cleaning equipment) is used to clear the blockage and restore flow. In the case of pump failure, the contractor checks the control panel and carries out emergency measures with the aim of restoring the water supply as quickly as possible.

Identifying the Cause

In parallel with emergency measures, or after the measures have been completed, the condition inside the piping is checked. In the case of water leakage, the location and extent of corrosion or cracks are checked. In the case of a blockage, the presence of oil and grease deposits, foreign objects, or poor pipe gradient is checked. If this step is omitted, there is a risk that the problem will recur while the cause remains unresolved. If a more detailed diagnosis of the inside of the piping is required, please consult us separately regarding an inspection using an endoscope camera.

Restoration Confirmation

After the work is completed, water pressure checks, leakage checks, and flow checks are performed to confirm that the system is functioning properly. Having the work details and results compiled into a report with photos makes it easier to explain the situation to owners and condominium management associations.
