Finding water on your floor is never a good surprise.
But detecting a leak is only the beginning.
A good water leak protection system should answer another question:
What happens next?
With a connected system, the process can move from detection to response.

Step 1: The Sensor Detects Water
A water leak sensor is placed near a location where water could cause damage.
For example:
-
Under a sink
-
Near a washing machine
-
Beside a water heater
-
Near a toilet
-
In a basement
When water reaches the sensor, it detects the leak.
This is why sensor placement matters.
A sensor can't protect an area it can't reach.
Step 2: The System Sends the Signal
Once water is detected, the information needs to reach the part of the system that can respond.
With AIWSH Q20 Pro, the leak detector and main valve communicate through ROLA wireless transmission.
The important part isn't the technical name.
It's what the connection allows the system to do:
The leak detector can communicate with the main valve without needing a wire running between them.
Step 3: The Main Valve Can Shut Off the Water
This is where leak detection becomes automatic water protection.
The main valve controls the home's water supply.
When the system receives the leak signal, the valve can close automatically.
That means you don't have to be standing next to the main water valve when the leak happens.

Step 4: The Alarm Lets You Know
Stopping the water is important.
Knowing that something happened is important too.
The Q20 Pro system also provides an audible alarm when a leak is detected, helping draw attention to the problem.
You can then inspect the area and determine what needs to be fixed.
Why This Matters When You're Not Home
Think about a washing machine running while you're at work.
Or a water heater developing a leak overnight.
Or a bathroom leak starting while you're away for the weekend.
You may not be there to see the first drop of water.
A connected leak detection and automatic shut-off system is designed to respond without requiring you to discover the leak first.

Detection and Shut-Off Are Different Jobs
It's easy to think a water leak detector and an automatic shut-off valve are the same thing.
They're not.
The detector finds the water.
The valve controls the water supply.
When they work together, the system can move from:
Detect → Signal → Respond → Shut Off
That's the bigger idea behind whole-home water leak protection.
