Chemical Resistance
Sustainability
The process of treating a water supply with
chlorine and ammonia is known as chloramina-
tion. The increased levels of chloramines found
in today’s potable water break down EPDM,
natural rubber, and nitrite rubber parts causing
premature failure. The AquaVantage
®
diaphragm
kit is made of chloramine resistant thermoplastics
and theroplastic elastomers that are engineered
to withstand the chemicals found in municipal
water supplies. The TPE elastomer used for
AquaVantage components has proven to with-
stand prolonged exposure to the same chemicals
that cut short the life of other diaphragm kits.
AquaVantage’s superior chemical resistance
provides the building owner with consistent
fixture/flush valve performance and reliable
water savings.
Casting Composition
Corrosion Resistance
AquaVantage flush valves are manufactured
from a special proprietary alloy formulated by
Zurn engineering to take advantage of low lead
content while ensuring the highest structural
integrity in tensile strength and yield strength.
The AquaVantage alloy also takes into consid-
eration the effects of dezincification on brass
castings. Testing shows the Zurn alloy is equal
to red brass for dezincification resistance.

Chemical Resistance
IMR independent laboratory test reports state “The Zurn diaphragms exhibited much greater
resistance to the monochloramine test solution than the Permex
®
diaphragms. The material
properties (hardness, mass, and volume) of the Zurn diaphragms exhibited a slow linear rate
of change. In contrast, the Permex
1
diaphragm material properties deteriorate rapidly after
156 hours of test exposure.” *ASTM D6284
Casting Composition
IMR independent laboratory test reports state “The Zurn valve body material performed as
well as the semi-red brass body under dezincification testing. Both the Zurn and semi-red
brass body materials were free of dezincification and meet the dezincification requirements
of a category 11 alloy per AS 2345-1992.” **
