    Post Noisy pipes when flushing?

    Once the toilet is flushed in our upstairs full bath, the pipes make this terrible fog horn sounding noise when filling the tank back. Please help?

    Sometimes a faulty vacuum breaker on the water line will cause this

    The exact thing is happening in our house...in the upstairs bath, when you flush the toilet....15-30 seconds later a lound noise, kind of like a horn or muffled alarm is heard throughout the house. Did you confirm the cause of the problem? I am on the verge of calling a plumber.

    It's either the fill valve, replace with fluidmaster 200,(most likely) or there is debris lodged behind the shut-off valve to the water closet.

    Yup, a common problem with fill valves just replace the ballcock with a new fluid master and your good. Easy to do and fairly cheap.
