TROUBLESHOOTING
IF FILL VALVE SHUTS OFF BUT CONTINUES TO LEAK
SLOWLY, repeat Step 12.
IF FILL VALVE TURNS OFF AND ON DURING PERIODS OF
NON-USE, it is a signal you are wasting water because:
• The end of the refill tube is inserted into overflow pipe, below
water level in tank. Attach refill tube to overflow pipe using "S"
clip provided.
• The flush valve is leaking because it's worn, dirty or misaligned
with tank ball or flapper (replace with a new flapper).
IF FILL VALVE WON'T TURN ON OR SHUT OFF or REFILL
OF TANK WATER IS SLOW after valve has been in use for
some time, Fluidmaster Model 242 Replacement Seal may be
needed.
