1:600 Fall ?

[Emtpencil]

How do you calculate the 1:600 fall ?

[bigred]

For every 600 inches or cm your gutter is long it should drop by 1 inch or cm. Measure the length of the complete run in cm say and then divide that measurement by 600, and thats the difference in height between both ends. You obviously have start at the level point first and come down by your calculated amount.
