Hi this is Fernando we are here with Expert Village and now we are going over some of the problem areas that you may have. Here you see a curve contour around a cement post this is problematic because normally like in the back yard we have a huge landscaping here a metal obstruction to prevent us so we have to pull that out. Which would effect our sprinkler system and sometimes it take a little extra work with that pick Axe to go ahead and clear the land as you would like to. The key thing is by clearing the land properly you would be able to go ahead and enter the pvc piping and manipulate the piping to some level of degree. When the pipping could take small turns but if it is a sharp angle then you would go ahead and just cut it and put in a joiner. So here I am again removing the dirt and keeping everything free from the house to make sure that it is done properly. Loosing the dirt with a shovel and removing it is a easy way not really. I'm Fernando and this is Expert Village.
