In response to Re: Pipe bang from sprinkler
: 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?

Try caping off half of the sprinklers. if this cures the banging, then you can either replace all the heads on that circut with low flow heads or split it into 2 circuts.
