I now how a water hammer in my house after irrigation was installed. We are on a well and this water hammer was not present before. The hammer is heard in the house each time the lawn valves go on. The company that put in the system doesn’t understand wells. I don’t know who to turn to since the water hammer is now happening in my house and not in the landscape area. What is the best way to go about a solution to fix this. What I really don’t know is what type of company who to call to fix this. The company must have experience of plumbing of Wells, Homes and irrigation system to handle this job. Any help would be appreciated. This is a drawing of the setup.
