Clearing Up ‘Pools’

While the “Aging Pools” article (April 4) was very informative, there was one statement to which I take exception. I found the sentence, “Two leak-finding companies currently operate in Southern California, American Leak Detection and National Leak Detection,” to be misleading. It implies that these are the only two companies that provide this service. This is not true. I am self-employed in the leak detection business and have been so for the past eight years with 30 years experience in the swimming pool and spa industry.
