What is WFSU in plumbing?
What is WFSU in plumbing?
The Water Supply Fixture Unit – WFSU – is defined by the American Uniform Plumbing Code (UPC) and is used to calculate the demand in water supply systems. The conversion can only be used for one or a few fixtures. When many fixtures are added up the number must be compensated due to the intermittent use of fixtures.
How is Wfsu calculated?
The total wsfu required is calculated like this:
- WCs: 4 X 10 wsfu = 40 wsfu.
- 2 Lavs: 2 X 1.5 wsfu = 3 wsfu.
- Total wsfu: 40 + 3 = 43.
- π·πππππ=48β(48β46)β(45β43)(45β40) π·πππππ=47.2 gpm.
How do I convert WSFU to GPM?
- 1 WSFU = 1 GPM = 3.79 liter/min.
- 1 in = 25.4 mm.
