Whistling sound coming from my plumbing system

Ask a Plumber

There’s a whistling sound that seems to come and go from my plumbing system. I can’t figure out the cause of it. What could be causing it?

  1. This type of sound you are describing is usually caused by a toilet fill valve that is slowly leaking. To locate the leak, remove the lid of each toilet tank and adjust the fill valve mechanism until it stops. Once you have found the noisy toilet, repair or replace the fill valve.

    There are many possible causes for this sound though. I would recommend recording the sound if possible and identifying when it typically occurs. For example flushing a toilet, dishwasher running or someone taking a shower.
