Aquaflush Trouble Shooting Guide
Care of Chrome plated surfaces.
The suggested cleaning of chrome plated surfaces is simply to clean them with soap and water then dry. Commercial cleaning compounds are
never recommended.
Seasonal use.
Valves usein installations subject to shut down because of cold and freezing conditions should be maintained in the following manner. After the
main supply has been shut off and the water drained from the systim, remove the stop valve cap and stop internals to allow the water to drain from
the flush valve itself.
*see previous for numerical references.
Problem
Cause*
Corrective Action*
Valve will not operate.
1.)
Stop valve is closed.
1.)
Open stop valve.
2.)
Supply valve is closed.
2.)
Open supply valve.
Insufficient volume of water
to adequately siphon fixture.
1.)
Stop valve is not open enough.
1.)
Open stop valve for desired volume of water.
2.)
Urinal trip mechanism installed in wrong kit,
urinal or closet
2.)
Replace urinal part with proper closet valve part.
3.)
Insufficient volume or pressure at supply.
3.)
If gauges are not available to measure supply pressure or volume of
water at the valve, completely remove the working parts and open
the stop valve to allow water to pass through the empty valve. If the
supply is adequate to siphon the fixture, the guide ring (#16) may be
removed from the guide assembly to provide additional flow. Should
this prove unsatisfactory, steps should be taken to increase the pres-
sure and/or supply.
Flush valve shuts off too
quickly.
1.)
Damaged or punctured diaphragm.
1.)
Install new P6000-EUR replacement kit to remedy the problem.
2.)
Enlarged by-pass orifice.
2.)
Install new P6000-ECR, P6000-EUR replacement kit to remedy the
problem.
Valve is short flushing.
1.)
Cylinder guide assembly and diaphragm assem-
bly are not tight.
1.)
Screw the two assemblies hand tight.
2.)
Enlarged by-pass orifice.
2.)
Install new P6000-ECR, P6000-EUR replacement kit to remedy the
problem
3.)
Urinal trip mechanism (black #12) in closet flush
valves.
3.)
Install closet trip mechanism(white) .
Valve is flushing too long or
not shutting off.
1.)
Trip mechanism not seating properly due to
foreign material between trip mechanism and
retainer disc.
1.)
Disassemble parts and rinse thoroughly.
2.)
By-pass orifice is plugged or partially plugged.
2.)
Examine by-pass orifice and clean if necessary being certain not to
enlarge orifice opening.
3.)
Line pressure is not adequate to force trip mech-
anism to seal.
3.)
Pressure is inadequate or has dropped below minimum operating
range. Steps should be taken to increase the line pressure.
4.)
Cracked cover.
4.)
Replace cover with new one.
Water splashes out of fixture.
1.)
Supply volume is more than is necessary.
1.)
Adjust downward on control stop.
2.)
Lime accumulation on vortex or spreader holes
of fixture.
2.)
Remove the lime build up.
Flush is not considered quiet.
1.)
Control stop may not be adjusted for quiet
operation.
1.)
Adjust the control stop for quiet operation keeping in mind the fixture
evacuation requirements.
2.)
Fixture may be contributing to noise.
2.)
Check noise created by fixture by placing a cover over the bowl open-
ing to separate valve noise from bowl noise. If it is determined the
fixture is too noisy consult with fixture manufacturer.
3.)
Piping system may be source of noise
3.)
High pressure in the system can sometimes be controlled by the stop
valve. Other sources of noise may be the absence of air chambers and
shock arrestors, loose pipes, improper size pipes, etc. In these cases
the building engineer should be consulted.
Chattering noise in flush
valve.
1.)
Segment diaphragm (#14) has been installed
upside down.
1.)
Reposition segment diaphragm as instructed by the markings on the
diaphragm (”this side down”).
2.)
The inside cover has been distorted by freezing
or abuse.
2.)
Replace both inside plastic cover and outside brass cover.
Handle assembly leaking.
1.)
Handle assembly is not tight.
1.)
Tighten handle assembly.
