There is a machine that cuts a slit, lays the pipe in and covers it
all in one pass. That makes the pipe part easy. It might not work up
there if you have the same "bank run gravel" type soil we had on the
PG side of the river tho.
How do you keep it from freezing?
I have air fittings in the valve supply lines. In the fall I turn off
the water supply, hook up an air compressor, and let the sprinkler
system controller cycle compressed air through each zone for a few
minutes each.
Say it ain't so.....
