How does flo distinguish a leak from normal use?

    Hi Robin, 

    In order to distinguish normal from abnormal, Flo uses a combination of sensors (flow, pressure, and temperature) in combination with proprietary machine learning. The machine learning enables us to essentially understand and assign fingerprints to the different types of common water events that happen in your home. When Flo sees something that doesn’t look like a normal event, that’s when you receive an alert notification and can take action or ignore. Most of these events are characterized by the flow sensor because it looks at the GPM (gallons per minute) and duration. The point of difference with our technology is that we use a pressure sensor to determine if there are any MicroLeaks in the system which typically you wouldn’t be able to find unless significant damage had occurred. With Flo, we do a daily test to ensure the home is leak free.

    Our device is able to capture flow rates as low as 0.3GPM. If your reverse osmosis system fills at a rate slower than this, it is possible that the health test (MicroLeak detection) will detect this as a small drip. If it fills at a rate of 0.3GPM or more it will register as water in use and restart the test later.

    The automatic shut off is based on the machine learning. A user is not able to set a duration shut off. With any catastrophic leak, there will be some time before Flo registers an unusual water flow event. This will be different for every home and is based on the regular water usage patterns. Flo will shut off the water to minimize damage to the home, rather than allowing it run for hours, or days.

    Just curious - do you have a Flo installed? I don't have any of those systems so can't say when it is called a leak. Mine has been installed for about a month now. It takes the first week to learn your habits. If I wash my car with the hose running, I will get an alert after about 20min. But maybe it would be different with your water usage?
