The new house has just moved in, and there is water seepage in the corner near the air conditioner. The property said that the air conditioner heated the defrosting water.

This situation should be that the outdoor unit is not waterproof or the outdoor unit is not equipped with a bracket, which makes it impossible to install the outlet of the outdoor unit on the centralized drainage pipeline after the outdoor unit is directly placed on the ground.

This should have little to do with the wall. It may be that the mezzanine of the air-conditioning seat is not waterproof, or there is something wrong with the design. No floor drain or centralized drainage is installed on the outer frame, or only the condensed water drainage pipe of the inner frame is installed, and no drainage pipe crossing for heating condensed water and defrosting water is reserved.

If it is a collective event, this can be settled through consultation with the developer or the property, and it is recommended that the owners collectively defend their rights.
