TROUBLESHOOTING AND MAINTAINING THE SLOAN
SERIES 900™ HYDRAULIC FLUSHING SYSTEM
Push Button Actuator Assembly
I. Leakage occurs at the Push Button.
Cause: Damaged or worn Seals or lime build-up in the Actuator
Cartridge.
Solution:Replace with new HY-32-A Cartridge.
II. Flushometer does not flush and a small amount of leakage is visible
on the fixture.
Cause: Foreign material is lodged in the Cartridge.
Solution:Remove and inspect Cartridge for foreign material. Clean
Cartridge under running water.
Cause: Damaged or worn Seals or lime build-up in the Actuator
Cartridge.
Solution:Replace with new HY-32-A Cartridge.
Cause: Plastic Tubing installed incorrectly.
Solution:Install Plastic Tubing correctly.
Actuator Cartridge Removal at Push Button
Plastic Push Button:
1. Loosen the Set Screw in the Button Flange and remove the Button,
Flange and Spring from the Actuator Body.
2. Unscrew the Cartridge from the Actuator Body.
NOTE: An automatic Check Valve in the Actuator Body allows
removal of the Cartridge without turning off the water supply.
Metal Push Button:
1. Remove the Button or Actuator Assembly from the wall or the
fixture
2. Disassemble the Flange or Button Assembly from the Actuator
Body.
3. Unscrew the Cartridge from the Actuator Body.
NOTE: The Metal Push Button was designed to be vandal resistant
and must be removed from the wall before servicing.
Flushometer Actuator Assembly
I. The Flushometer does not flush or flushes only once and will not flush
a second time when the Button is pushed.
Cause: The Plunger is lodged in the Actuator Cartridge or the Plunger
bypass hole is clogged.
Solution:Remove the Actuator Housing and Cartridge from the
Flushometer. Clean under running water. If Cartridge Parts are
worn, deteriorated, or limed up and the problem persists after
cleaning, replace with new HY-83-A Cartridge (item 29).
Cause: Plastic Tubing installed incorrectly.
Solution:Install Plastic Tubing correctly.
Actuator Removal from the Flushometer
1. Turn off water at the Control Stop (item 11).
2. Unscrew the Housing Coupling Nut (item 26) from the Flushometer.
3. Remove the Valve Actuator Housing (item 22) from the Flushometer. The
Tubing (item 25) can be left intact.
4. Remove the Actuator Cartridge Assembly (item 29) from the
Flushometer Body. Care should be taken upon removal so that the
Actuator does not abruptly separate due to spring compression within. If
the Actuator Cartridge is lodged in the Body Cavity, grip the exposed
portion gently with a pair of channel-lock pliers and rotate back and
forth to loosen the “O” Ring seal.
5. Separate the Actuator Housing to reveal the Spring and Plunger. Inspect
for wear and, if necessary, replace with new Actuator Cartridge
Assembly (item 29).
Flushometer Service
I. The Flushometer does not function.
Cause: The Control Stop or main water supply valve is closed.
Solution:Open Control Stop or main water supply valve.
II. The volume of water is insufficient to adequately siphon the fixture.
Cause: The Control Stop is not open wide enough.
Solution:Open Control Stop for desired delivery of water.
Cause: Urinal Inside Parts installed incorrectly in a Closet Flushometer.
Solution:Replace with correct Closet Inside Parts kit (see item 7).
Cause: Inadequate volume or pressure at the water supply valve.
Solution:If no gauges are available to properly measure the supply
pressure or the volume of water at the Flushometer, completely
remove the entire Diaphragm Assembly (item 7). Open the
Control Stop and let water pass through the empty Flushometer
Body. Make sure that the water supply is adequate to siphon the
fixture. If this does not provide a satisfactory siphon, steps
should be taken to increase the water supply pressure and/or
volume.
III. The Flushometer closes off immediately.
Cause: The Diaphragm is ruptured or damaged.
Solution:Install new Inside Parts Kit (see item 7).
Cause: The bypass hole is enlarged from corrosion or damage.
Solution:Install new Inside Parts Kit (see item 7).
IV. The length of the flush is too short.
Cause: The Diaphragm (item 5) and the Guide Assembly (item 6A, B,
C, D or E) are not properly tightened.
Solution:Screw Diaphragm and Guide Assembly together and tighten by
hand (see diagram for item 7).
Cause: The bypass hole is enlarged from corrosion or damage.
Solution:Install new Inside Parts Kit (see item 7).
Cause: Urinal Inside Parts installed incorrectly in a Closet Flushometer.
Solution:Replace with correct Closet Inside Parts kit (see item 7).
V. The length of the flush is too long or continuous.
Cause: The Relief Valve of the Inside Parts Assembly (item 3A, B, C
or D) is not seating properly or the bypass hole is clogged with
foreign material or by a gelatinous film caused by “overtreated”
water.
Solution:Disassemble the working parts and wash under running water.
NOTE: THE SIZE OF THE DIAPHRAGM BYPASS ORIFICE IS OF UTMOST
IMPORTANCE. DO NOT ENLARGE OR DAMAGE THIS HOLE. DO NOT USE A
PIN OR OTHER SMALL OBJECT TO REMOVE DIRT FROM THIS ORIFICE.
Cause: Line pressure has dropped and is no longer sufficient enough to
force the Relief Valve to seat properly.
Solution:Close Control Stop until adequate pressure has been restored to
the line, then reopen Control Stop.
VI. Water splashes out from the fixture.
Cause: The water supply volume is more than required.
Solution:Throttle down Control Stop to reduce volume.
Cause: Lime has accumulated on the vortex or spreader hole of the
fixture.
Solution:Remove lime accumulation.
