For some reason my pipes have suddenly started thumping when I flush my toilets. The thumping seems to be coming from the location where the main enters the basement. I thought maybe the vacuum breaker on the sprinkler system was bad, which is directly adjacent to the where the main comes into the house, but the thumping continues even after I close the sectional valve that controls the lawn sprinklers which is upstream of the vacuum breaker. the pressure in the system has not increased (city water). Any thoughts \ tips | or suggestions on localizing the issue would be appreciated. Thank you.
