- 9. Water Supply Fixture Unit (WSFU) WSFU are used to determine the water demand in water supply systems. One WFSU for a single unit corresponds to one GPM. 1 Water Supply Fixture Unit (WSFU) = 1 GPM Example. One water closet is valued at 6 fixture units Therefore, 1 WC × 6 FU WC × 1 GPM WSFU = 6GPM
