When testing flexible fittings, at what pressure should the test be conducted?

The appropriate pressure for testing flexible fittings in underground storage tank systems is generally 5 Psig. Conducting the test at this pressure ensures that the fittings can withstand potential operational pressures without being exposed to excessive stress. This testing approach is critical in preventing leaks, maintaining system integrity, and ensuring safety compliance with environmental regulations.

By performing the test at 5 Psig, technicians can effectively evaluate the performance and durability of flexible fittings under realistic operational scenarios. Testing at this pressure helps identify any weaknesses or potential failure points in the fittings before they are put into service. This standard practice minimizes risks related to leakage or failure, thereby protecting the environment and enhancing the reliability of the storage system.
