I just finished installing a 6 station sprinkler system. My stop and waste is about 6 feet away from my foundation. The system goes through a back flow preventer. I ran a 1 1/4" line around the back of the house to the rear valves. On one of the valves, when it shuts off, it causes pipe bang inside the house. What can I do?
