Run pipe under footing or through stone wall?
I would like to run pipe from my basement well pump to a hydrant in the yard. I could run the pipe out the basement wall built in 1904 of fieldstone, OR run it to an adjacent heated 24-inch crawlspace and under the footings there, 48 inches below grade.
I am not sure which would be more difficult. There is not much room in the crawlspace to dig a hole deep enough, even though the outside is accessible. Is there a trick to send a pipe underneath on one side and up on the other?
Or, in the basement, would a rotary hammer work to make a hole through 18 inches of stone and mortar?
I am also prepared to hammer and chisel through the stone if that's the best option - I have done that before.
What is the best way?
