3. PROBLEM: Length of flush too short (Short Flushing) or
Valve closes off immediately.
CAUSE: (a.) Piston Assembly is not hand-tight.
(b.) Enlarged Bypass orifice from corrosion or damage.
(c.) Urinal Piston in Closet Flushometer.

4. PROBLEM: Length of flush too long (Long Flushing) or
fails to close off.
CAUSE: (a.) Piston is not seating properly or Bypass orifice is
clogged because of foreign material, or Bypass orifice
is clogged by an invisible gelatinous film from “over-
treated” water.
(b.) Line pressure has dropped and is not sufficient to
force Relief Valve to seat.
(c.) Main Seat is fouled with debris or is worn.
SOLUTION: (a.) Disassemble the working parts and wash thoroughly.
NOTE: Size of the orifice in the Bypass is of utmost
importance for the proper metering of water into
the upper chamber of the valve. Do not enlarge or
damage this orifice. Replace Piston if cleaning does
not correct problem.
(b.) Shut off all control stops until pressure has been
restored, then open them again.
(c.) Clean or replace Main Seat.

CAUSE: (a.) The B-85 Seal may have deteriorated.
(b.) Handle Gasket has been omitted.
(c.) Valve Handle Bushing is worn.
(d.) Handle Trim Ring is reversed preventing gasket from
sealing (Crown II only).
SOLUTION: (a.) Install new B-85 Seal.
NOTE: The B-85 Seal will easily slide onto the
Bushing if it is wet.
(b.) Install A-31 Handle Gasket or Sloan Handle Repair Kit
(CR-1007).
