Automatic water leak detection & shutoff for basements, utility rooms and rentals. Pair Bulldog valve robots with ELS leak sensors so a detected leak closes your main line in seconds.

Shop shutoff systems & sensors

• Bulldog valve robots in Z-Wave for hub control or Matter over Wi-Fi for broad ecosystem support.
• Integrated-valve kits for clean installs on common 3/4″–1″ mains.
• ELS100 leak sensors (multi-packs) for laundry, sinks, water heaters and sumps.
• Relay/dry-contact options for alarm panels and BMS integrations.

Why it matters

• Prevent damage: auto-shutoff on detection limits costly remediation.
• Remote control: close/open from the app or automations while travelling.
• No pipe cutting: clamp-on robots use the valve you already have.
