Found backflow preventer leaking water. The city is working on the waterlines in the neighborhood. Homeowner is going to put a cup under the backflow preventer. I turned the ball valve off to the feed of the system. If the bowl fills up with water, the backflow preventer has not reset and must be replaced. I am going to add an estimate for replacement of the pressure reducing valve backflow, preventer kit, just in case it needs to be replaced
