What must be done before a standpipe system is connected to a water source?

Before connecting a standpipe system to a water source, flushing the system is crucial. Flushing helps clear any debris, sediment, or potential contaminants that may be present in the pipes before water is introduced into the system. This step ensures that the water supply entering the standpipe is clean and free from particles that could obstruct flow or damage the system components.

While pressure testing, dry testing, and backflow prevention are important aspects of overall system maintenance and compliance with safety standards, flushing specifically targets the need to prepare the system for optimal functionality and reliability when it is put into service. By ensuring the removal of impurities, flushing plays a vital role in maintaining the integrity and effectiveness of the fire protection system.
