On my toilets, both fill tubes are connected to the OUTSIDE of the overflow tubes, so the stream of water is going directly to the tank.

I went ahead and directed the stream to now go into the overflow tube.

Will this help the performance of the toilets now?

  • You have two fill tubes?

Yes. That's how it's supposed to be.

You have water coming out by the tube which has the on/off mechanism and a small flexible pipe that is expected to send water inside the overflow tube to refill the bowl. Without that, the bowl is not likely to refill much, actually.

I uploaded a video on YouTube to show it in action.

    ...I think you mean bowl, not tank. Or pan, not cistern for our cross-ponders.
