Some common emergency overflow situations include the following:
1.Equipment malfunction overflow: For example, when a water heater, washing machine, or other plumbing equipment leaks or malfunctions, a floor drain can help discharge the overflowing water and prevent water from entering the interior of the building.
2.Overflow caused by natural disaster or natural disaster: In the case of rainstorm, flood or other natural disasters, the floor drain can play the role of drainage, helping to drain the excess water out of the building and reduce the water level inside the building.
3.Overflow caused by blocked drainage pipes: When the drainage pipes are blocked, the floor drain can serve as an emergency drainage outlet to reduce internal pressure in the pipes and prevent water from flowing back into the building.
Although floor drains can partially help prevent emergency overflow, for more severe flood situations, other measures still need to be taken, such as installing waterproof equipment and improving the waterproof capacity of buildings. In addition, regularly checking the condition of floor drains and ensuring their patency is also an important measure to prevent emergency overflow.
