Frequently asked questions

How do leakage switches work?

VIWA Watersafe detects water leaks through sensors that react to contact with water. When a leak is detected, a signal is sent to the main unit, which immediately shuts off the water via the solenoid valve – before damage can occur.

Is it possible to connect multiple sensors to one system?

Yes, you can connect up to 99 wireless sensors to a single system. This makes it easy to cover all the risk zones in your home – such as the kitchen, bathroom, laundry room or under the dishwasher.

What happens in the event of an alarm?

In the event of an alarm, a signal is sent to the main unit, which automatically shuts off the water. At the same time, an alarm sounds and an indicator shows where the leak has been detected. You quickly gain control of the situation and can fix the problem before the damage becomes serious.

Can I install the system myself?

The main unit's solenoid valve must be installed by a qualified HVAC installer. For our wireless and our home packages, the sensors are already pre-programmed to their main unit. However, it is very easy to connect more sensors, door switches and signal amplifiers to an existing system yourself, without an HVAC installer.

Does the system need electricity to function?

Yes, the main unit is powered by electricity via the included power adapter. The wireless sensors are available in two versions, with battery operation (2xAAA) or with a power adapter. In our wired systems, the main unit and sensor are in a single unit and are powered by a power adapter.

What happens if the power goes out?

Depending on the type of solenoid valve you choose to install. We normally ship with "Normally open" which means that when there is no voltage to the solenoid valve, the solenoid valve is in the open position. This means that in the event of a power failure, the system will switch to the open position. However, our system can be programmed to be connected to a solenoid valve that is "Normally Closed" which means that voltage is required to the solenoid valve at all times to be open and allow water to flow.
However, this means higher wear on the solenoid valve.

Can I use VIWA Watersafe in holiday homes?

Absolutely. It is in holiday homes in particular that water leaks are often discovered too late. VIWA Watersafe reacts immediately and turns off the water even if no one is there.

Does the system work in all types of housing?

Yes, the system is available in several designs: for apartments, villas, townhouses or offices. We have both wireless and wired systems and different valve sizes depending on the pipe dimension.

Can I use the system for coffee machines in the office?

Yes! We have ready-made solutions for office environments where leaks from coffee machines or dishwashers, for example, can cause expensive damage. A small, smart system easily protects the entire kitchenette.

What is the difference between a wireless and wired system?

A wireless system has a main unit combined with a sensor that can receive signals from wireless sensors and door switches, which is suitable for properties where you want to secure multiple risk zones. The wireless main unit is normally installed on the incoming water line.

The wired system (those marked with a blue dot on the shell) consists only of a combined main unit and sensor to which it is not possible to connect any wireless sensors, which is suitable for a point-by-point installation.
