Note:sump not shown Precise alignment and make-up The matched taper bell and spigot joint on the primary does not always result in a precise and predictable insertion depth.This variation results from: • Manufacturing tolerances in the bell • Differences in length of tapers prepared on the job site • Difference of insertion depth when dry fit and after adhesive has been applied. Flexible sump penetration fitting installation • Measure to the appropriate height for the center of the hole • Check the height from the ground making sure to allow for the desired slope for the piping in the station layout. • Mark the center • Measure and mark the center from side to side on the flat panel.For round sumps, see note below. • Using a 5-inch hole saw,cut a hole for the penetration fitting.
