1. Lay string line or straight edge across the tank riser at finished grade height.
2. Cut the riser pipe so that the top edge will be 17-19" (430-480 mm) from finished grade. The
actual height (elevated grade) of the bucket will be 1.0" (25.4 mm) above finished grade to ensure
proper water run-off (sloped dome).
APT® AND UPP® PIPE: S L O P E
As a common recommended practice, underground piping can be sloped back to
underground tank for natural drainage of fuel inside pipe to drain back to the tank.
Franklin Electric does not require the sloping of APT® XP piping as a warranty or
installation requirement but recommends the sloping of pipe at 1/8th inch per foot as
a best practice. The sloping or non-sloping of piping is to be determined by Certified
APT® XP or UPP® installer at time of installation and reflect any local code or marketer
preference. Vapor return lines should have a slope of 1/4" per foot (2 m every 100 m)
and never less than 1/8" per ft (1 m every 100 m) back towards the tank farm, unless
in-line joints such as elbows are to be used. Trench corners should have a radius of 5
ft (1.5 m).
NOTE: Cut the riser pipe square/perpendicular to endure a flat sealing surface.

1. Remove an appropriate size section of concrete around the existing spill container.
The minimum recommended size is a 36" (914 mm) square around each spill container.
2. Remove existing spill container.
3. Excavate a 24" (610 mm) diameter by 24" (610 mm) deep (measured from top of riser)
around the riser pipe.
NOTES:
4. Check the height of the riser pipe compared to finished grade level. Lay a straight edge across
the excavated area and measure from grade to the top of the riser pipe. The riser pipe must be
between 17 - 19" (430 - 480 mm) below grade.
5. If the riser pipe is too long, it must be re-cut or replaced to obtain appropriate length.
