What does the refill tube do in a toilet tank?

The refill tube is an integral part of the system, as it tells the overflow tube how much water to input into the bowl. Without a properly functioning refill tube, the toilet bowl will either have no water, or overflow with too much water.

What is the black tube in toilet tank?

The overflow tube leads to the bowl. It prevents the tank from overflowing, by directing extra water to the bowl. Nothing prevents the bowl from overflowing, other than the fact that once the water level reaches a certain height the toilet flushes.

Is the fill tube supposed to go into the overflow tube?

The Refill Tube must be located above the Overflow Tube. If it’s pushed down into the Overflow Tube, it can siphon water from the tank into the bowl causing the Fill Valve to cycle on and off.

Should there be water in overflow tube?

The maximum water level in the tank should be about one inch below the overflow pipe. If the float valve doesn’t operate properly, the cold-water feed may not fully switch off, causing the water level to continue to rise above the overflow.

Where does the toilet overflow tube drain to?
