Can a double check valve reduce pressure?
Yes, one double check valve closure can reduce differential pressure across the other and create a complete, leak-proof seal. A double check valve, also known as a Double Check Assembly or DCA, is designed to prevent backflow and is usually installed in water systems to prevent contamination.
Are a backflow preventer and a check valve the same?

Not at all. A backflow preventer has a fail-safe design and is used to prevent water contamination in hazardous situations. A check valve is used in low-hazard situations and is used to prevent reverse flow.
