Why are assemblies installed in parallel?

Assemblies are installed in parallel primarily to maintain service while testing or repairing. This setup allows one assembly to remain operational while the other is taken offline for maintenance. By doing so, the overall system can continue to function without interruption, ensuring that there is a continuous supply of water. This is particularly important in situations where backflow prevention is critical for health and safety, as it ensures that systems can be tested or repaired without risking water supply disruption.

The capability to keep systems operational is crucial in various applications, especially in commercial and industrial settings where a constant water supply is necessary. It allows for compliance with regulations and standards while ensuring that the integrity of the water supply system is maintained throughout necessary maintenance procedures.
