Repair Parts and Maintenance Guide

IMPORTANT: The CROWN

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/6.0 Lpf closets and

1.0 gpf/3.8 Lpf urinals) prohibit use of higher ﬂush volumes.

1. Valve DOES NOT function.

A. Control stop or main valve is closed. Open control stop or main valve.

B. Handle assembly is worn. Install Sloan handle repair kit, or replace

handle.

C. Relief valve is worn and sticking in UP position. Replace piston.

2. Insufﬁcient volume of water to adequately siphon ﬁxture.

A. Control stop not open enough. Adjust control stop for desired delivery

of water.

B. Urinal piston parts inside a closet valve. Replace piston parts with

proper closet piston.

C. Low consumption valve installed on a non-low consumption ﬁxture.

Replace with proper ﬂushometer. Crown

ﬂushometers are not

available with ﬂush volume higher than 1.6 gpf/6.0 Lpf.

D. Inadequate volume or pressure at supply. Increase water pressure or

supply (ﬂow) to valve. Consult factory for assistance.

3. Length of ﬂush too short (short ﬂushing) or valve closes off

immediately.

A. Piston assembly is not hand-tight. Screw the assembly hand-tight.

B. Enlarged bypass oriﬁce from corrosion or damage. Install NEW inside

parts kit to correct problem and update ﬂushometer.

C. Urinal piston in closet ﬂushometer. Replace piston with proper closet

piston.

D. Low consumption piston installed in non-low consumption ﬁxture.

Replace with proper ﬂushometer. Crown

ﬂushometers are not

available with ﬂush volume higher than 1.6 gpf (6.0 Lpf).

E. Handle assembly worn. Install Sloan handle repair kit.

4. Length of ﬂush too long (long ﬂushing) or fails to close off.

A. Piston is not seating properly or bypass oriﬁce is clogged because of

foreign material, or bypass oriﬁce is clogged by an invisible gelatinous

ﬁlm from “over-treated” water. Disassemble the working parts and

wash thoroughly. NOTE: Size of the oriﬁce in the bypass is of utmost

importance for 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. Line pressure has dropped and is not sufﬁcient to force relief valve to

seat. Shut off all control stops until pressure has been restored, then

open them again.

C. Main seat is fouled with debris or is worn. Clean or replace main seat.

5. Leaking at handle assembly.

A. The B-85 seal may have deteriorated. Install new B-85 seal.

NOTE: The B-85 seal will easily slide onto the bushing if it is wet.

B. Handle gasket has been omitted. Install A-31 handle gasket or Sloan

handle repair kit.

C. Valve handle bushing is worn. Install Sloan handle repair kit.

CARE AND CLEANING

DO NOT USE abrasive or chemical cleaners (including chlorine bleach) to

clean ﬂushometers that may dull the luster and attack the chrome or special

decorative ﬁnishes. Use ONLY mild soap and water, then wipe dry with

clean cloth or towel.

While cleaning the bathroom tile, the ﬂushometer should be protected from

any splattering of cleaner. Acids and cleaning ﬂuids will discolor or remove

chrome plating.
