		Question
		What do I need to do to get my faucet certified using two A112.18.3-certified check valves?
		Answer
		When the backflow protection devices have already been certified, a faucet manufacturer needs only to identify the NEOPERL® check valve part numbers used in the faucet. The faucet will then be subjected to the tests normally required by A112.18.1, including backflow and back siphonage, but not the life test.
