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.

urinal or closet.
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 pressure and/or supply.

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
chambers and shock arrestors, loose pipes, improper size pipes,
etc. In these cases the building engineer should be consulted.
