TROUBLESHOOTING CHART
SYMPTOMS PROBABLE CAUSES CORRECTIVE ACTION
1. Fill valve turns on/off by itself
without toilet being flushed.
A. No slack in flapper chain assembly, holding
flapper off seat.
A. Adjust flapper chain assembly for proper
slack.
B. Flush valve flapper ball worn, dirty or
misaligned with flush valve seat; or seat cor-
roded so flapper will not seat.
B. Inspect, clean and, if necessary, replace
flapper ball and/or seat.
2. Fill valve continues to run,
allowing water to enter tank.
A. Foreign particles lodged under the float
valveseal(locatedunderllvalvecap).
A.Shutoffwatersupply;removellvalve
cap assembly by rotating 1/8 turn counter-
clockwise. Cover uncappedlower valve unit
with an inverted cup (holding it to prevent
overspray), and turn water on and off a few
times.Cleanllvalvesealsurface(located
underoatvalvecap).Replacellvalvecap
assembly by engaging lugs and rotating 1/8
turnclockwise.Turnwateron.Installlterin
supply line to prevent recurring problems.
B. Fill valve seal (located under float valve cap)
may be cracked or split.
B. Replace seal.
C. Tank water level set above overflow level. C.Duringllcycle,holdfloatunderwaterafew
secondstoallowittollwithwaterballast.
Adjust float by adjust the cross-shaped
thread on float rod and sliding float up or
down on float rod until water level is at
marked water line.
D.Waterleakingpastflushball. D.Replaceflushball.
E. Trip lever binding, holding flush ball open. E. Turn trip lever nut clockwise to loosen until
trip lever on longer binds.
3. Incorrect water level height. A. Valve float cup does not contain enough
water to provide required ballast.
A.Duringllcycle,holdfloatunderwaterafew
secondstoallowittollwithwaterballast.
B. Float height incorrect. B. Adjust the cross-shaoed thread on float rod
until water level is at marked water line.
4.Longornoisytankllcycle. A. Plugged valve inlet or supply line. A. Perform Corrective Action 2.A.
5. Poor flush A. Water level is too low. A. Adjus tank waterlevel.
B. Trapway or rim holes are obstructed. B. Unclog trapway; clean rim holes.
C. Soil pipe or vent is obstructed. C. Clean obstruction from soil pipe or vent.
D.Supplyshut-offvalvenotfullyopen. D.Opensupplyshut-offvalve.
6. Toilet overflows. A. Toilet trapway is obstructed. A. Use plunger to unclog.
