How is a hydrostatic leak test performed on newly welded hydrant lines?

Question

We are installing new external yard hydrants at our manufacturing facility in Nashik. Our vendor is scheduling a hydrostatic test. What is the test pressure and duration required to certify the line?

FirePause Experts · Accepted Answer

According to IS 13039 guidelines, newly installed fire hydrant lines must undergo hydrostatic testing at a minimum pressure of **15 kg/cm²** (approx. 215 PSI) or 1.5 times the maximum working pressure (whichever is higher) for a minimum duration of **24 hours**. This ensures all welded joints and flanges can withstand pressure spikes without leaking. A detailed report must be signed by the licensed fire safety agency.
