IMPORTANT: The
GEM Flushometer is engineered for quiet
operation. Excessive water flow creates noise, while
too little water flow may not satisfy the needs of
the fixture. Proper adjustment is made when plumbing
fixture is cleansed after each flush without splashing
water out from the lip AND a quiet flushing cycle is
achieved.
Never open Control Stop to where the flow from the valve
exceeds the flow capability of the fixture. In the event
of a valve failure, the fixture must be able to accommodate
a continuous flow from the valve. |

ATTENTION
INSTALLERS: With
the exception of the control stop inlet, DO NOT USE
pipe sealant or plumbing grease on any valve component
or coupling! To protect the chrome or special finish of
Sloan Flushometers, DO NOT USE toothed tools to install or
service these valves. Use our A-50 Super Wrench or other
smooth-jawed wrench to secure couplings. Regulations for
low consumption fixtures (1.6 gpf closets and 1.0 gpf urinals)
prohibit use of higher flush volumes. |

| |
A) Control
Stop not open enough. |
| |
B) Urinal
piston parts inside a closet valve. |
| |

PROBLEM: |
|
|
LENGTH
OF FLUSH TOO SHORT, 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 |
|
D) Low
consumption piston installed in non-low consumption fixture. |
|
E) Handle
assembly worn. |
|
|
SOLUTION: |
|
|
A) Screw
the assembly hand-tight. |
|
B) Install
new inside parts kit to correct problem and update flushometer. |

PROBLEM: |
|
| |
LENGTH
OF FLUSH TOO LONG OR FAILS TO CLOSE OFF |
|
| |
CAUSE: |
|
| |
A) Piston
is not seating properly, 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) A
3.5 GPF closet piston has been used in a 1 or 1.5 GPF urinal
or on a 1.6 GPF toilet. |
| |
D) 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 by-pass is of utmost importance in 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) Replace
with proper piston. |
|
D) Clean
or replace main seat. |

PROBLEM: |
|
|
LEAKING AT HANDLE ASSEMBLY |
|
|
|
CAUSE: |
|
|
A) The
B-39 seal may have deteriorated. |
|
|
B) Handle gasket has
been omitted. |
|
|
C) Valve handle bushing
is worn |
|
|
|
SOLUTION: |
|
|
A) Install
new B-39 seal. NOTE: The B-85 seal will easily slide onto the
bushing if it is wet. |
|
|
B) Install
G-35 handle gasket or Sloan Handle Repair Kit G-50-A. |
|
|
C) Install Sloan Handle Repair Kit G-50-A, or
replace handle. |
