Imagine a scenario with me. You opened up your wallet and poured out a bunch of money for an irrigation system so that you would have total control over watering your yard and plants. Or maybe you didn’t even have the irrigation system installed, yourself. Maybe you just bought the house, partly because the realtor mentioned that it has an automatic watering system.
That sounded awfully convenient at the time. Nobody wants to get all tangled up, dragging a hose and manual yard sprinkler around the yard. That would be both boring and frustrating — and worse, it’s WASTEFUL! When you turn on a hose sprinkler and walk away, you are nearly guaranteeing that you will forget that you turned it on in the first place, and you will end up wasting hundreds or thousands of gallons of water.
