Field of the Invention: The present invention relates to a system and method that provides remote access to the lock with its special lock structure applied to water treatment devices and allows for only the authorized service accessing the interior of the device under user supervision.

The invention relates to a system and method that prevents floods caused by the water treatment device or the pressure of the mains water and provides information to the user by measuring the amount of water entering the water treatment device and the pollution rate.

State of the Art:

The water treatment device ensures to obtain drinking water by filtering the tap water and purifying the same from all harmful substances therein. The filters of the water treatment device must be replaced with new ones periodically. However, people, who are not authorized service personnel, replace said filters with the filters that are not original and lack certain materials, cause the installed filter not to fulfill its task. Water filters that cannot fulfill their task reduce the quality of water and may negatively affect human health. The water to be consumed from the water treatment devices with filters that fail to perform their tasks causes users to get sick, poisoned or even death. Thus, it is very important to prevent access to water treatment devices other than the authorized service.

Sellers who introduce themselves as authorized services cause users to make mistake by giving users fair prices. Non-original filters mounted to water treatment devices cause deterioration in the taste of the water. Moreover, non-original filters cause the water treatment device to be fall out of the warranty scope. The resulting problems may lead to an infamous impression of water treatment device companies on users and cause them to be stuck in a difficult situation. After water cut is experienced in the existing water treatment devices, the relevant public institution (Municipality) sends the water by increasing the pressure while the water is returned. The amount of pressurized water supplied to the houses leads to water overflow by causing cracks in the pipes of the water treatment device. Moreover, water floods may occur in the houses due to the loosened parts used over time, because of the problems arising from the production of the water treatment device. Such conditions lead to great financial losses.

Users who are not able to see the contamination of the water entering the water treatment device have doubts regarding the time when to change their filters. Users have to drink unhealthy water by continuing to use the filters they have forgotten to replace. Besides, people who have difficulty in seeing have also difficulty in reading the information on the water treatment device.
