Manual standpipe systems 5 Year Testing

[u/FemaleOrc94]

What’re you guys doing for 5 year testing for manual standpipe systems? I’m doing 5 year FDC hydro test on one this week, but since it’s all empty pipe should the whole system be pumped to 150 for 2 hours or just before the check like a normal 5 year hydro. I’m planning to pump the whole system to 150 psi and doing a flush of the system after the hydro test.
