Notes:
If digging bars are used for leverage, protect the pipe with at minimum, a 2" x 4" block in good condition.
Never “hammer” on pipe that does not seat. Check alignment, then apply pressure with a digging bar again. In difficult situations where pipe is
properly lubricated and aligned, use one digging bar to maintain pressure and a second bar to apply additional pressure.
In most cases, when pipe is properly seated, you will feel/hear a slight pop. If the spline will not easily insert into the hole, then the pipe has not
been seated properly.
