Replacing section of lawn sprinkler pipe

As I think more about it, maybe another approach will work.
There is 5 feet of pipe between the house and the walkway, 5 feet
under the walkway, and 12-15 feet more to the manifold.
1. I dig on both sides of the walkway until all the pipe is exposed.
2. I cut and remove the section between the walkway and the house,
and cover the exposed end to prevent soil from entering during step
5. 3. I cut the pipe on other side of the walkway, leaving a 1-foot
"stub," and remove the pipe all the way to the manifold.
4. I connect the replacement pipe to this stub with an ordinary
lawn-pipe connector that slips inside both ends. (I pour hot water on
the ends of the pipe to make inserting the connector easier.)
5. I simply push the new pipe under the walkway toward the house and
cut off the old section after it emerges.
Of course there will be the friction of the soil to overcome. But the
break is under the walkway, so before starting the above, I'll simply
turn on the water for a couple of seconds so the water coming out of
the break will act as a lubricant.
Have I overlooked something?

get a piece of 1" pvc thick walled pipe. glue a hose thread female
adapter to one end. put a hose thread male end on the other end.
dig a trench long enough on one side of the walk deep enough to get
below the walk and any stone base. hook a hose to the female end. use
a brass hose nozzle on the male end. turn water to hose on full
blast. adjust nozzle to get a powerful thin jet. insert pipe in
trench and aim nozzle under the walk. you'll probably jet a hole under
the walk in less than 30 minutes. remove both ends of the pipe and
use it either directly, or thread your new pipe through it.
