I am going to be helping a friend install an underground sprinkler for his house. We sent off a drawing and other required data to a manufacturer for free design and material lists. I have two questions;
1. How to drill under the driveway to get control wires and pipe to the other side.
2. In Denver we used poly pipe but here in Houston PVC pipe is more common. Is one better that the other? I found poly pipe easier to work with.
