Query: Not Reliable, don't buy this model, save your water.

used it one season and towards the end of last summer i noticed the shut off valve was allowing water to continously pass thru. Ouch, how much water did i waste last year? Its a new season and i forgot all about that valve. I set it up and was testing the program and realized after the valve closed water was still getting by. I had to post this so others don't make the same mistake.
