 Sent me, we don't have a sprinkler system per se. We have a hose timer connected to our outside faucets. Well, I understand. That's kind of a clock timer. You screw it into the outside faucet and then screw the hose into it and then have your sprinkler. So it comes on and off at preset times and certain times of the day and so on, which is great. Some of them are pretty sophisticated, actually. Sometimes we get a thunk.
