How it works

Mount Bulldog over your existing levered quarter-turn ball valve (no pipe cutting for clamp-on models).
Place leak sensors at high-risk spots; when water is detected, Bulldog closes the main automatically.
Control locally or via your platform (Matter/Wi-Fi) or smart-home hub (Z-Wave).

Why it matters

Prevent damage: auto-shutoff limits remediation costs and insurance claims.
Remote control: close/open from the app or automations while travelling.
Retrofit-friendly: clamp-on robots use the valve you already have; integrated-valve kits available.

Leak protection FAQ

Will Bulldog fit my main water valve?

Bulldog is designed for levered quarter-turn ball valves (common 3/4″–1″; larger sizes available). Check clearance around the handle for clamp and rotation.

Do I need a smart-home hub?

No for Matter/Wi-Fi kits (EVC300/EVC400). Yes for Z-Wave (EVC200 & Jasco Z-Wave sensors) — use a compatible hub.

How many leak sensors can I add?

Bulldog Wi-Fi/Matter kits typically support multiple sensors (often up to 20; confirm per SKU). Place them at water heater, laundry, sinks, and the mechanical room.
