Home Flood Protection

Aside from burglary protection our alarm/HA system offers some other features;

Fire Monitoring: Individual smoke/heat detectors connected to the alarm system and monitored remotely.
Freeze Protection: If the temp drops below 6 degrees the alarm monitoring company is notified.
Hydro Status: If the power fails a zone is tripped.

To this I wanted to add proper flood protection.

All critical functions of our home setup are delegated to the alarm system as it has proven itself reliable. This way detection and notification are handled by the alarm system and any automated response is handled by the HA system. If the HA system fails a notification is still sent to the alarm system, and by extension me.

The proposed arrangement is to have two Water Detectors (these are fundamentally just two metal probes that trigger an alarm when water completes a circuit between them) installed – one under the water heater and the other by the supply lines in the laundry room. Water detected in either area will trigger an alarm which will in turn notify the HA system.

This will be augmented by a Zwave Motorized Controller for the main water shutoff valve. Once a water leak is detected the water for the house can be automatically shut off.

At least that’s how it should work in theory.

    With respect to, ‘This will be augmented by a Zwave Motorized Controller for the main water shutoff valve.’

    That’s interesting. I’d have expected the device to be installed inline with the water supply. But I suppose remotely manipulating the ball valve directly has the benefit of their only needing ‘one size’ for both 1/2″ and 3/4″ supply lines :-)

    This device has a few other benefits as well….should the device fail then it can be replaced without the need to engage in any plumbing activity, but most importantly the integral units weigh in at around $600 right now, almost 4x the price of these external actuators.

    It was simple economics – you know I’m not afraid of plumbing anymore.

    ;)
