When I flush my toilet, the shower leaks for a duration of time afterward. The leaks stop after the tank is filled. I seem to hear it more at night than during day time. Plumber doesn't know what's causes the leak. However, I don't remember that he actually flushed the commode or open the sink faucet.

Do you know what might be causing it or advise of a source for info? HELP - the NOISE is driving me nuts.
Thank you so much. GT

Shower and Toilets are two independent fixtures. Flushing toilet should not make shower leak. I suggest you call a licensed plumber and have him to take a look at it
