Notes:

---|---|---|
1.
|
For fixtures not listed, factors may be assumed
by comparing the fixture to a listed one using water in similar quantities
and at similar rates.
| |
2.
|
For fixtures with both hot and cold water supplies,
the weights for maximum separate demands may be taken as 3/4 of the
total supply fixture unit value.
