Also, to anyone laying a sprinkler system. Don't run them ontop of one another! It's a pain if you ever have to maintenance it.
You might never need to use it, but PVC isn't exactly very expensive for a nice backup plan in the future.
Agreed.. When trenching, professionals should keep the pipe spacing within a trench of 1" and have no more then 3 pipes in a trench... As a repair aspect
Backup plans only last for so long as the person who installed it will tend to forget what he did exactly . Standard installation procedures are best to keep to
