What type of testing procedure is required for dry pipe systems?

Hydrostatic testing is the appropriate procedure for dry pipe systems. This test involves filling the piping system with water and pressurizing it to ensure that it can withstand the pressure without any leaks. Hydrostatic testing is essential for validating the integrity and strength of the system after installation or maintenance work, ensuring it can handle the pressures that may be experienced during operation.

This testing method verifies that all joints, fittings, and the piping itself are secure and free from defects. It is a critical step in the inspection process, as dry pipe systems rely on stored water to be released during a fire event, and any potential weakness in the system could compromise safety and effectiveness.

While performance testing, functional testing, and visual inspection are important aspects of system maintenance and ensuring operational readiness, they do not specifically address the critical need to ensure the physical integrity of the piping under pressure, which is uniquely assessed through hydrostatic testing.
