After the delivery of the house, if the owner finds it, he can make a claim, and the loss will be paid by the construction unit or deducted from the reserved maintenance fund for engineering quality problems. If a party fails to perform the liability for compensation, it may bring a lawsuit to the local people's court.

There are two ways to prevent electric leakage from harming human body:

1. Ground the metal shell of the electrical appliance. The grounding body can be an all-steel water pipe or a steel bar in the wall, which can make the contact better.

2. Install the leak switch. If the insulation of electrical appliances, live wires and neutral wires in the house is poor, even if there is a small leakage, the leakage switch will have protective action and the power supply will be disconnected. When the leakage device is eliminated, it can be switched on and sent. This is a very safe measure.
