How deep do my irrigation pipes need to be?

A:

My recommendation is to bury sprinkler lines 8-12 inches. I usually try to keep a standard depth of 10" because it provides more safety if I need to do some type of ground work so I don't have to worry about hitting lines. A walk-behind rototiller generally won't go deeper than 8". From a freezing perspective, 7-8 should be fine since it's not frequent to have temperatures below freezing for extended durations. I would still winterize your lines by blowing them out with compressed air.
