How can I fix a plumbing issue between toilets in adjacent bathrooms?

Our house has 2 bathrooms where the toilets are back-to-back. When toilet #1 is flushed, the water in the bowl of toilet #2 moves. Water in bowl of toilet #1 does not move when toilet #2 is flushed. Is there an issue with the plumbing that I need to address?

    Hi KL, I would say thay are both using the same air return pipe but I would call some plumbing places and ask. You may find someone that will tell you.

    I only noticed this issue recently. Does mean something happened to caused this?

  • Hi, KL!

    I think that as long as both toilets are flushing the way they are supposed to and not backing up or overflowing, it isn't a cause for concern. It wouldn't hurt to call a plumber to check! I hope this helps!

    Thank you for all your responses. They are flushing fine. Will call plumber for advice.
