The owner of this company will tell you to look at his web site - that he is a registered and licensed Texas Irrigator. He is not according to the TCEQ. He is a liar and a horrible repair tech. He broke more than he fixed on my property. I confronted him in his marijuana stupor about using used parts on my system and he said they work the same, but a used sprinkler head with old springs in it is not the same as a new one. This person is of very low character and has many false statements on his web site.
