I got a callback immediately. I told him my ex-husband was outside trying to "fix it" himself and I would call him back later that evening. I even had JEA come out and look at the main drain that night, to no avail, so I called Mr. O'Connor about 10:00 P.M. He told me he would be out by 10:00 A.M. the next day. He was very understanding about the late call, even came earlier than planned because he knew I was in dire straights with a main line back-up, not very pretty. He was quick, efficient, got the job done and even checked a bathroom I previously had problems with and told me it was fine. Very reasonably priced also.
