Important:
• All plumbing is to be installed according to state and local
codes and regulations.
• Water supply lines need to allow proper water flow for each
fixture.
• Flush all lines of any debris before making connections.
•Donot use pipe sealantorplumbing grease on anyfittingother
then the control stop inlet.
The Aquaflush valve is designed to operate under various
water pressures with a recommended range between 10 and
100 psi (69 to 689 kPa). Each Zurn valve is tested for proper
performance at the factory before being shipped. Consult the
product pages of the catalog for available flow options.
Most low consumption fixtures (1.28 and 1.6 gallon) require
a minimum of 25 psi running pressure through the valve to
obtain proper evacuation. Please be sure to consult fixture
manufacturer on minimum running water supply requirements
for proper evacuation.
Wheninstalling your quality Zurnvalve it is recom mend ed that
to protect the polished finish you do not use a toothed wrench.
This will cause gouges and scratches on your valve.

1.Install stop valve assembly using proper size supply
escutcheon and sweat solder adapter kit if applicable (see
1). Thread sealing compounds should be used on male NPT
threads only.
Aquaflush®Installation Instructions
3.Insert the flush valve tailpiece into the stop valve and hand
tighten the lock nut to the stop valve. Plumb the entire unit
(see 3).
4. Determinethe length of vacuum breakertube required tojoin
theflushvalveandfixturespud. Cut the vacuum breaker tube,
if re quired, to this length (see 4a). Assemble the vacuum
breaker tube assembly and spud nut assembly to the flush
valve and fixture spud (see 4b).
5. Hand tighten spud nut and vacuum breaker tube nut to fixture and flush valve. Adjust the valve assembly for plumb. Tighten
fixture spud nut, vacuum breaker tube nut and lock nut with a wrench.
2. Prior to inserting the flush valve tailpiece into stop valve, be
certain that the O-ring seal is located in O-ring seal groove at
the end of the tailpiece and the locking nut and locking snap
ring are located as shown below (see 2). Care should be
taken not to damage the O-ring when inserting the tailpiece
intothe stop valve. If lubricationis needed, wettingthe O-ring
with water will be sufficient.

FV250 Rev. A 7/25/18 Page 5
6. When all flush valves are connected to the fixtures and water
pressureisavailable,itisrecommendedthatthesupply piping
beflushedtoremovedirt,pipechips,etc.fromsystem. Before
the water is turned on, be sure all stop valves to the flush
valves are closed off tight. The stop valves can be opened
and closed by using the adjusting screw located at the center
of the stop valve cap, behind the stop snap cap screw cover
if already installed (see 6a). Stop valve adjustments can only
be made by using the adjusting screw. It is not neces sary
to remove the stop valve cap when making adjustments.
If for any reason it becomes necessary to remove the
stop valve cap, be certain the water is shut off at the
main supply valve.
Aquaflush®Installation Instructions
This procedure should also be followed when the system
has been drained for some time, as occurs in athletic fields,
recreation parks, etc.
7. The Aquaflush flush valves are preset for fixture volume as
marked on the valve cartons. The valve does not require
regulation for vari a tion in water pressure within its operating
range. To set the flush valve for proper operation, gradually
adjust the stop valve open, using the adjusting screw, while
actuatingthevalve until the rate ofwaterflowintothe fixture is
notexcessive,yetissufficientenoughtoadequately evacuate
the waste. The final setting for urinals should be such that
the fixture will not overflow when the valve is actuated in
succession. The stop snap cap screw cov er should be
secured after final adjustments have been made.
Use the following procedure to flush out the supply piping:
A. Remove the main valve body cover.
B.Remove the working partsfromthe flush valve (shownin6b).
C.Replace the main valve bodycover and plasticcover without
reinstalling the working parts.
D. Open the stop valve by using the stop adjusting screw, and
flush out all debris from pipe and connections.
E. Shut stop, open cover, replace the working parts, replace
plastic cover and main valve body cover and tighten.

Care of Chrome Plated Surfaces
The suggested cleaning of chrome plated surfaces is simply to clean them with mild 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 system, remove the stop valve cap and stop valve
internals to allow the water to drain from the flush valve itself.
*See previous page for numerical references.
Aquaflush®Trouble Shooting Guide
Problem Cause* Corrective Action*
Valve will not operate. 1.) Stop valve is closed.
2.) Supply valve is closed. 1.) Open stop valve. 2.) Open supply valve.
Insufficient volume of wa-
ter to adequately siphon
fixture.
"1.) Stop valve is not open enough.
2.) Urinal trip mechanism installed in wrong kit, urinal
for closet.
3.) Insufficient volume or pressure at supply.
1.) Open stop valve for desired volume of water.
2.) Replace urinal part with proper closet valve part.
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 (see page 5). Should this prove
unsatisfactory, steps should be taken to increase the
pressure and/or supply.
Flush valve shuts off too
quickly. 1.) Damaged or punctured diaphragm.
2.) Enlarged by-pass orifice. "
1.) Install new P6000-EUR or P6000-ECR replacement
kit to remedy the problem. (#12 thru #17)
2.) Install new P6000-EUR or P6000-ECR replacement
kit to remedy the problem. (#12 thru #17) "
Valve is short flushing. 1.) Diaphragm kit is not matched to the fixture.
2.) Urinal trip mechanism (black #12) is in the closet
flush valve.
"1.) Install the proper P6000-EUR or P6000-ECR
replacement kit to remedy the problem. (#12 thru #17)
2.) Install closet trip mechanism (white #12).
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.
2.) By-pass orifice is plugged or partially plugged.
3.) Line pressure is not adequate to force trip
mechanism to seal.
4.) Cracked cover. (#11)
1.) Disassemble parts and rinse thoroughly.
2.) Examine by-pass orifice and clean if necessary
being certain not to enlarge orifice opening.
3.) Pressure is inadequate or has dropped below
minimum operating range. Steps should be taken to
increase the line pressure.
4.) Replace cover with new one.
Water splashes out of
fixture. 1.) Supply volume is more than is necessary. 2.) Lime accumulation on vortex or spreader holes of
fixture.
1.) Adjust downward on control stop.
2.) Remove the lime build up.
Flush is not considered
quiet. 1.) Control stop may not be adjusted for quiet opera- tion.
2.) Fixture may be contributing to noise.
3.) Piping system may be source of noise.
1.) Adjust the control stop for quiet operation keeping in
mind the fixture evacuation requirements.
2.) Check noise created by fixture by placing a cover
over the bowl opening to separate valve noise from
bowl noise. If it is deter-mined the fixture is too noisy
consult with fixture manufacturer.
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.
Handle assembly leaking. 1.) Handle assembly is not tight. 1.) Tighten handle assembly.
