• Water supply lines need to allow proper water flow for each
fixture.
• Flush all lines of any debris before making connections.
• Do not use pipe sealant or plumbing grease on any fitting other

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.

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.
