Here in Iowa the frost line is 4' so I am replacing this 4" CI pipe that has totally rotted out, with schedule 40 pvc , some of the CI was in the ground, out of 16' maybe 4' was in the ground and there is one heat run running through this crawl space but I don't think it's heated, and the crawl space is attached to the basement but not real accessible, I am only asking because this will get inspected, so do I need to bury it 48" in the crawlspace
