We have used L.E. Isley & Sons Plumbing since 1970 and usually they do a good job for us. This last time though, their service was only about average. We had a small leak in a three-inch pipe and they suggested that we get a mechanical engineer to take care of the problem. There was also some odor coming from the pipe. We ended up fixing it ourselves by simply having my son cap off the pipe. So, all they did this time was pretty much just diagnose the problem.
