Why does the depth of a pipe matter?

The depth of the pipe burial matters because that will affect how effectively the weight will be distributed. Keep the pipe too close to the surface and it will have to support too much weight. You’re not giving the surrounding soil enough of an opportunity to manage the burden.

Can PVC pipes break?

PVC pipes can support a decent amount of weight, but they are still susceptible to breaking. They will need additional support especially if they’re being asked to bear the weight of a vehicle. That’s where the soil comes in. If the soil is tightly packed, it can absorb some of the weight being placed on the PVC pipe.
