There was an old system on the ground originally but did not work. J and J services did a great job reconfiguring and installing my sprinkler system for 1/2 the price that other companies quoted. It works great! My only negative is that when installing the new pipes in the ground, they cut the grass away and placed it back instead of cutting the grass and flipping it to the side so that the roots were still in tact. All of the grass that they cut to place the pipes died so I have a trail of dead grass where the pipes are located. I had to remove the dead grass that wasn't rooted and add soil and sod and start from scratch to grow the grass.
