Protect your home from water leaks and water damage


Protect your home from water leaks and water damage with Waterlock, the leak protection and mains water shut-off system.

Waterlock gives customers peace of mind and control of their home’s water supply whether home or away. Unlike most systems on the market today, it not only detects standing water, low temperature and high humidity conditions, but can instantly shut off the mains water supply automatically without any manual intervention.

IMPORTANT: Before purchasing Waterlock, you must ensure that the product is suitable for your home. The system is only 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 our pre-purchase video before proceeding with your purchase.

This package is for self-installation.


Detection and action – Waterlock not only detects leaks but also closes the valve automatically. Leaks can be detected by the sensors placed around the home, either by the presence of standing water or an increase in humidity levels in the area. You can also remotely control the mains water with the valve using through the app.

The Waterlock app simply and remotely manage the home’s water supply. The app also provides notifications at the first sign of a leak, change in humidity or temperature.
