Supply Line
An old friend hired someone to renovate his front and back lawn with new sod, install front and back sprinklers and do some cement work. I guess the guy screwed up the cement so bad that he was asked to leave. The cement work has been completed by someone else. The 1st installer started to run pvc pipes for the sprinklers, but I really can't figure out, what kind of plan he had. Anyway, I plan on tapping into the service line (1") in the front lawn, and running it to the back, under a sidewalk, about 6 ft wide. The previous installer had run 2 ea 3/4" pvc pipes under the sidewalk. Would it be better to (1) split the 1" line from the service line, thru both 3/4" lines and then rejoin them in the backyard; (2) just use 1 of the 3/4" lines and then go back up to 1"; or (3) attach a 1" line to one of the existing 3/4 lines with an adapter and try to drive it under the sidewalk? Realizing #3 is probably the most desireable, but requires the most work.
