No one is immune from such an accident as the bay of the neighbors' apartment. In order not to waste your nerve cells when flooding a neighbor's apartment and to keep costs to a minimum, act rationally and clearly.
If you flooded your neighbors, then, firstly, call an emergency dispatch specialist to take measures to eliminate the accident. This will minimize damage from flooding the neighbor's apartment.
Secondly, with the help of an employee of the emergency dispatch service, sort out the reasons for the incident of the gulf of the apartment. The accident may have occurred due to a technical problem, for example, improperly installed plumbing products or equipment that had manufacturing defects, or for another reason. If there are signs of a technical problem, be sure to save the broken parts. They will be needed to determine the cause of flooding during an independent examination.
It is also possible that the accident was your fault. For example, if you installed plumbing products or plumbing equipment with defects on your own, or violated SNiP norms during installation, which caused a leak. And also if you have not turned off the tap. In this case, ask a specialist to give you recommendations on how to eliminate all violations and how to protect yourself for the future.
Thirdly, if the neighbors' apartment was flooded through your fault, and you do not deny it, then meet with the neighbors from below and try to independently resolve the issue of compensation for damage from the gulf of the apartment through negotiations, without bringing the matter to court. If you think that your fault in what happened is not, then you need to conduct an independent examination and get its conclusion. It is necessary to refer to it in court.
Fourthly, if you are unable to resolve the situation with your neighbors through negotiations, and if your guilt is obvious, then you should be present when drawing up an act on the inspection of the damaged property. When inspecting, pay the attention of the commission members to the condition of the inspected apartment.
Fifth, if you do not agree with the amount of damage indicated in the apartment gulf assessment report, then you can apply in court for a forensic examination of the apartment gulf. In this case, it will be best if an experienced lawyer will represent your interests and prepare all the necessary documents.
