A condition known as “phantom flush” causes your toilet to turn on and off for a few seconds at random. A steady water leak from the tank into the bowl causes this, which is frequently caused by sediment build-up on the flapper or a broken flapper seat. The minerals in hard water clogged the flapper, stopping it from fully closing. The replenishing process is activated if more water seeps out of the tank, resulting in a “phantom flush.”

The following are some possibilities:

An Improperly Installed Flapper Chain

When the toilet is flushed, the flapper chain permits the flapper to raise up and down as needed. If the chain is not properly attached, the flapper’s capacity to completely close the hole will be hampered, resulting in a toilet that runs at random.

A Leak in the Fill Valve

After the toilet is flushed, the fill valve is in charge of refilling the tank. Water may remain to fill the tank if this valve is broken or leaking, causing the toilet to remain flushing. The toilet may be running at random due to a sluggish, periodic leak.

Not Enough Water

If the water level in the tank isn’t right, the toilet may flush at random The fill valve should be 1 to 2 inches below the water level. If it’s higher or lower than this, the off-balance will almost definitely result in a phantom flush.

A Faulty Toilet Handle

A lever that stays or doesn’t snap backup could potentially be the source of the problem. The lever can leak extra water into the tank if it does not return to the original place after flushing. This may lead the toilet to flush at odd times.
