Double Check Assemblies (DCA)


Double check valve assemblies (DCVA) are the most commonly approved type of device for inline underground sprinkler systems and a good choice for interior or underground installations. These backflow preventers are less susceptible to frost damage because they are usually installed below ground or in a basement making sprinkler system winterization much simpler.
