There are two main types of anti-flooding systems for companies:
- wi-fi anti-flooding systems with sensors to be placed on the floor, where there is a greater risk of breakage, leaks or infiltrations;
- detectors installed along the water pipeline, which monitor the water flow.
These two types of anti-flooding systems perform different functions, but they can be used in a complementary way.
The wi-fi anti-flooding systems are also called passive systems. They include sensors that are sensitive to contact with water, which are positioned in areas that present a greater risk. When these sensors get wet, the system sends an alarm signal via wi-fi.
Among the disadvantages of most passive systems there is the fact that they do not automatically block the flow of water, but require an intervention for it. Moreover they are battery operated, and this latter must be checked regularly.
Instead, the “smart” water flow detectors are based on preset values and stop the flow itself as soon as they detect any anomaly. For this reason they are also called active systems.
Their effectiveness in preventing water damage is certainly greater, moreover they have the advantage of having a mainly mechanical operation, which does not require electrical power and is able to function even in the event of a blackout.
This type of anti-flooding systems (for companies but also for residential use) include the WATERBLOCK and E-WATERBLOCK devices designed by ELTEK Appliance.
