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 used in 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.
Problem
Possible 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 piston installed in closet valve.
2.) Replace urinal piston with proper closet piston.
3.)
Insufficient volume or pressure at
supply.
3.)
Consult fixture guide for minimum gallons
per minute flow and running pressure for
satisfactory performance.
Flush valve shuts off too
quick.
1.) Damaged piston.
1.) Install new P6200-EC, P6200-EU replacement
kit to remedy the problem.
2.)
Enlarged by-pass orifice.
2.) Install new P6200-EC, P6200-EU replacement
kit to remedy the problem.
Valve is short flushing
1.)
Enlarged by-pass orifice.
1.) Install new P6200-EC, P6200-EU replacement
kit to remedy the problem.
2.) Urinal piston installed in closet valve.
2.) Replace urinal piston with proper closet piston.
Valve is flushing too long
or not shutting off.
1.) Trip mechanism not seating properly
due to foreign material between trip
mechanism and seat.
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 mechanism to seal.
3.) Pressure is inadequate or has dropped below
minimum operating range. Steps should be
taken to increase the line pressure.
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 opening 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 chamber and
shock arrestors, loose pipes, improper size
pipes, etc. In these cases the building engineer
should be consulted.
Handle assembly leaking. 1.) 1.) Handle assembly is not tight.
1.) 1.) Tighten handle assembly.
