Symptoms
Probable Cause
Recommended Action
1. Poor flush.
A. Water level is too low.
B. Improper drain line
venting.
C. Poorly adjusted rod.
A. Raise the tank water level to the marked waterline.
Turn the white knob on the fill valve clockwise.
B. Install venting according to code.
C. Verify that the threaded rods behind the faceplate
make contact with the flush buttons. If they do not
make contact, thread the rods out to the correct length,
and tighten the nuts to lock the rods in place.
2. Fill valve does not shut
off.
A. Water level is too high.
B. Flush valve gasket or flush
valve are damaged.
C. Flush valve is sticking
open.
A. Lower the tank water level to the marked waterline.
Turn the white knob on the fill valve counterclockwise.
B. Replace the flush valve gasket or flush valve as
necessary.
C. Check the flush valve and actuating mechanism for
free movement. Push button actuators should raise the
levers and then spring back without force. Replace
components as necessary.
3. Leaks from behind the
bowl.
A. Gaskets are not positioned
correctly.

Reposition the gaskets if needed. Lubricate the gaskets
so they slide over the mating part they seal. Reinstall
the bowl, making sure the gaskets stay in the correct
position.

flex when used.
A. Insufficient support for the
frame.
A. Add additional support members, and mount the
frame with 3/8" or larger lag bolts.

the tank is closed.
B. There is an obstruction in
the water line.
C. Fill valve debris screen is
plugged.

B. Close the external water supply stop, then disconnect
the braided hose where it attaches to the fill valve. Turn
on the water supply and check the flow through the
hose. Inspect the entire water path for obstructions.
Clear any blockage.
