How to Read Vari-Pitch™
.
The patented Vari-Pitch™
vial was developed to assist in setting slope/pitch on
projects such as plumbing, driveways, patios, sidewalks,
landscaping, gutter installation and more. Whenever drainage
or flow of water is a factor in your next project, use an Empire level with the Var-Pitch™
vial.
.
Level Position See photo 1
Vial markings indicate
level and inches-per-foot-of-pitch from 1/8" to 1/2" per
foot in 1/8" increments; see images for raised slope
per foot. The bubble in the vial indicates level when
the right edge of the bubble is touching the "zero" line..
.
Pitch Position See photo 2
When right edge of
bubble touches the 1/4" mark, the pitch or slope runs
high to right, low to the left at a rate of 1/4" per
foot. Example: A 4 foot length of drain pipe would drop
1" from right to left, water flow to the left. Images
show increments of greater pitch.
