Protects your home from leaks and gives you control over your home’s water supply.


The Waterlock system automatically acts when it detects standing water associated with major leaks, instantly shutting off the mains water supply. It also alerts you to changes that indicate a slow drip leak through changes in temperature and humidity near the sensor.

In addition, the system gives you control of the mains water supply, allowing you to turn it off remotely when you are away using the Waterlock app, protecting the home and giving you peace of mind. It’s even compatible with Alexa.

The system can have up to 12 wireless sensors which can be placed in high risk areas around the home such as kitchens, bathrooms, utility rooms or boiler cupboards.


IMPORTANT: Before purchasing Waterlock  ensure the product is suitable for your home. Waterlock is compatible with 15mm or 22mm copper or plastic pipes (not lead) which are in good condition. There must be ample access to the stopcock and surrounding area for the system to be fitted.

To help you establish whether your home is suitable, please watch the pre-purchase video.
