STEP 1: Check if the water level in your tank is set to the manufacturer’s water line. Adjust the fill valve by turning the body of the fill valve counterclockwise to unlock it.
STEP 2: Move the fill valve down to the marked waterline or half an inch below the top of the flush valve overflow tube. Once the fill valve is readjusted turn the body of the fill valve clockwise to lock back into place.
STEP 3: If the flapper is closing right after you flush, the chain has too much slack. Adjust the chain to have minimal slack and trim any excess chain.
STEP 4: Also, please ensure the chain is going as straight up and down as possible from the flush lever.
STEP 5: If these tips don’t resolve your issue, you may have an incorrect flapper and it needs to be replaced. Find a new flapper here.
