I have a set of 5 control values above ground with each zone's pipe
about 1 1/2 feet under the ground. Due to a leak, I just dug up all
of the dirt in between the pipes and replaced all of it.
So, the question is, is there any disadvantages to leaving these pipes
alone and not putting the dirt back in? It took me a better part of
the day to dig out the hard clay soil, rock, etc. and I don't want to
go searching for a leak 5 to 10 years down the line.
As for an underground sprinkler box, the one's that I saw at Orchard
Supply were way to small.
