I have a brandnew sprinkler system. the neighborhood water went out and here was my backflowdevice sqirting water out for 3 hours .Is that normal. I had water comming to the house at a very little rate and it was squirting out of the backflow in a pretty big amount,and that for 3 hours.Once the waterproblem in the nieghborhood was fixed it stopped squirting out of the overflow.Help ..doesnt that get expensive having water running for 3 hours?
Thanks
