Recommended Action
A. If poor flush occurred for heavy waste
while using the short flush button, use the
long flush button.

was previously used, the tank may not
have refilled completely. Check the
position of the water supply shut-off
valve. If required, fully open the valve or
wait longer between flushes.
C. Check for clogged trapway or rim holes.
Clean if necessary.
D. Check for clogged soil pipe or vents. Clean
if necessary.
E. If poor flushes occur with full tanks and
clean trapway, rim holes, soil pipes, and
vents, then the pump may be the problem.
Check that the pump hoses are
undamaged and are properly installed.
F. Power interruptions or extreme low
voltage conditions can prevent pump
operations. Check that the proper electrical
power is applied to the pump.
G. If the problem persists, replace the pump.

valve head. Flush the lines.

plugged. Clear particles from valve seat.

the supply stop valve.

fill valve. If the fill valve was clogged,
install a filter in the supply line to prevent
recurring problems.

split. Replace the valve assembly.
