Hi, I would like to leave my household water on if I'm ever away for extended periods. I have a few items that occasionally use water such as a motion sensing sprinkler (few seconds) to scare critters from the garden. What I'm looking to do is detect any amount of constant flow (using an in-line flow sensor) from a pipe leak or burst, over an extended period (few minutes adjustable), and subsequently cut the power to my 120V water pump. Thank you in advance for your help.
