WATER LEVEL IN BOWL IS TOO LOW
• Make sure the refill hose is supplying water
down the overflow pipe.
• Water level in tank may be too low. Raise
water level to 1/2" below top of overflow pipe.
• Flapper may be closing too soon. Give flapper
chain approximately 1/2 " of slack. Adjust
flapper to higher setting.
• If your toilet is 3.5 gallons per flush or larger,
the flapper in this kit may not be the correct
flapper.Pick up a 501 Harsh Water flapper or
504 all rubber flapper by Fluidmaster.
CAUTION: Do not shove refill tube down
overflow pipe. This will cause loss of water
from tank. Make sure the end of the refill tube
is higher than the water level of the tank.
