Water Splashes When Toilet is Flushed

  • Transcript

    LESLIE: Now we’ve got Matt in Wisconsin who’s dealing with a splashy toilet. That is the worst: constantly cleaning a toilet seat. Tell us what’s going on.

    MATT: Well, when we flush the toilet, a good portion of air comes up through the trap, forcefully enough to cause the water to splash up onto the seat or the inside of the lid if it’s closed.

    TOM: Well, what really causes that, Matt, is a venting problem. Is this a new problem or has it always been this way?

    MATT: No, it’s just within the last couple of months.

    TOM: OK. So then what I suspect is that you’ve got a blockage somewhere. If your vent for that toilet is partially blocked, then the drain line is being starved with air. And if it’s starved with air, it’s going to try to gulp that air from somewhere else and that’s what’s causing the bubbles.

    MATT: OK.

    TOM: So, what you need to do is try to figure out where that obstruction is. And it’s going to be somewhere in the vent that is connected to the waste line under the toilet, if that helps you narrow it down a bit.

    MATT: Yes, it does. Thanks.

    TOM: You’re very welcome. Thanks so much for calling us at 888-MONEY-PIT.
