Zooz ZAC36 Titan Water Valve Actuator

Image coming soon

Quick verdict

The ZAC36 clamps onto your existing ball valve and gives you Z-Wave control over your home's water supply. Pair it with a few ZSE42 leak sensors and Home Assistant, and you have automated water shutoff when a leak is detected. The price is premium, but it is insurance against catastrophic water damage.

Standout: Clamps onto your existing ball valve for automated Z-Wave water shutoff. No plumber, no pipe modifications.

Local control facts

Home Assistant: zwave_js integration, Local Push (home-assistant.io, checked Oct 10, 2026)
Z-Wave JS: in the device database, listed as Zooz ZAC36 (Titan Water Valve Actuator) (github.com, checked Oct 22, 2026)

Why it stands out

clamps onto your existing ball valve with no plumber needed for installation
ships with a wired leak probe that closes the valve by itself, even if the hub is offline or you have no Z-Wave controller at all
pairs with ZSE42 leak sensors for fully automated water shutoff on leak detection
strong motor handles ball valves up to 1.25-inch (per Zooz) ball valves, covering most residential mains

Reasons to hesitate

premium price, but cheaper than water damage
requires AC power, so it needs an outlet near your main water shutoff
bulky actuator motor sticks out from the valve, so tight spaces may be a problem

Best for

whole-home water shutoff automation paired with leak sensors
vacation homes or rental properties where a leak could go unnoticed for days

Avoid if

your water shutoff valve is not a standard ball valve, since the clamp may not fit
you do not have a power outlet near your main shutoff

Privacy and local-control notes

Fully local Z-Wave device. No cloud account needed. Your water valve control stays entirely on your local network.

Home Assistant support: supported · integration path: Z-Wave JS.
