Why won't the flapper in the toilet close?

The problem is caused by too much slack in the lifting chain that connects the flush lever to the flapper. When the chain has too much slack, it cannot lift the flapper high enough to allow the full amount of water to flow down through the flush valve; it closes prematurely, thereby stopping the flush.

Similarly, you may ask, how do I make my toilet flapper stay open longer?

Open the tank and test the tension on the flapper chain by pulling up on the center. You shouldn't be able to pull it up more than about 1/2 inch before the flapper starts to rise. Alternatively, push down on the flush handle to test the tension. The flapper should start to rise before the handle is halfway down.

Subsequently, question is, how do you fix a weak toilet flush? Using a toilet bowl cleaner, for example Lime-A-Way® or Clorox®, hold the flapper open and pour 1–2 cups of cleaning solution down the flush valve opening. Be careful to not let any cleaner spill over into the tank. If it does, wipe it up immediately. Let the toilet sit unused for several hours or overnight.

Also to know, how do you fix a toilet that runs intermittently?

  1. Turn off the water supply to the toilet tank.
  2. Open the toilet tank lid.
  3. Unlatch the flapper chain from the clip on the back side of the flush lever.
  4. Reach into the toilet tank and pull up on the flapper arms.
  5. Place the replacement flapper over the toilet tank drain, right side up.

Why does my toilet have a weak flush?

Toilets usually lack flushing power because the waste pipe, siphon jet, or rim jets are partially clogged, or the water level in the tank or bowl is too low. In those cases, clear the blockage and adjust the system to correct the water levels.
