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? :confused:

Re: Noisy pipes when flushing?

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

Re: Noisy pipes when flushing?

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.
