what is minimum water level before the sensor will detect a leak? Looks like it cannot be mounted flush with the floor

This needs a slightly longer answer :). First, the sensor detects water as soon as water touches both the electroplated conductors at the bottom of the sensor. But there are two plastic bars to the side of these conductors which raise them about 1/16th of an inch from the floor. So, the quick answer would be that it takes around 1/16th of an inch of water or more for the sensor to trigger an alarm. Now, about flush mounting to the floor: The gap using the plastic bars is provided for a reason. In most cases, floors hold some moisture under normal circumstances. Even when they seem to be dry. But if you were to place the electrodes flush on ground, they could very well pick up this moisture and start sending alerts, which would appear as false alerts. Hence the small gap.Having said that, if you have an application where you not for sure this is not the case and the floor (or any surface of interest where you want to place the sensor) is completely dry in normal cases, you can shave off the plastic side bars to the point where the metal clips touch the floor. Then, any moisture/ water on the surface will trigger the sensor right away, without having to wait for the level to rise to 1/16th inch or more. Hope this answers the question :)

If I lose power at home, wouldn't I lose the router that provides access to the network to send an email / text?

Think of it as a feature:) On two occasions we've lost power and had to leave our house. When the power comes back, I get a notification that the sensor is again reachable which tells me the power is back and we can go home!

Is it possible to set up the system so that the alarm does not go off but you still get a text/email?

Absolutely. The audible alert is programmable in 3 ways. 1. Trigger normally, keep beeping. 2. Trigger normally, snooze after set time period, 3. Turned OFF. You can change these settings any time, from the cloud interface on your phone or computer.
