Lengthen or shorten chain until flapper stays open on
its own.
WHEN TOILET IS FLUSHED THE
SEALANT RING SEPARATES FROM
THE SEAT
• The surface is either not clean enough or wet. Purchase
a new SEALANT RING # 2602.

of tank are correctly set.

LEVER HOLE (B).
2. WATER LEVEL (C) is set below top of
Overflow Pipe (Fluidmaster recommends
1/2”).
3. THE CRITICAL LEVEL MARK / C.L. Mark

The default setting for the PerforMAX™ flapper is preset at (9) for larger tanks.
Start with the dial in the default setting and flush your toilet.
If your toilet is able to flush, adjust the dial down to the next setting, number (8) and flush again.
Continue to adjust dial down one setting until your toilet is unable to flush properly. When the flapper dial is on a
setting that does not allow for a proper flush, adjust the dial back up one setting.
HINT: The higher the number set in front of the chain connection, the longer the flapper will stay open. Turn
clockwise for greater flush volume. Turn counterclockwise for lower flush volume.
