Full Description

The ANSI/NSF Standard 61/ Section 9 protocol is critically evaluatedfrom the perspective of the leaching solution chemistry. A detailed examination revealsthat the test water is roughly representative of a typical water supply. However, somelower pH and lower alkalinity waters tend to be much more aggressive than the existingsection 9 water, which may cause utilities problems with first draw compliance for thelead and copper rule, even for products that are section 9 certified.
