I am a widow of senior years in Weimar Texas and this man blew the cap off of my sprinkler system (I watched him do it), then put a new one on, tested it and presented me with a bill (including the new cap) which I refused to pay. I've used him for a couple years and paid directly for his services....He sneaked back on my property and removed the new cap, which was trespassing! I intend to turn him in to the Better Business people if he does not return and replace the cap he blew off. Texas had no freezes this winter, besides the water main to my system had been turned off all winter. I am very disturbed about this and I do hope this causes others to concider a more knowledgeable person, to work on your sprinkler system. No I do not recommend Greg Cowart's "No Hoses Irrigation" to anyone!
