The idea for o5 Plumbing started decades ago with the childhood friendship of Eric Keigher and Chris Metzger. The two took different paths into the plumbing business: Chris went into the plumbing trade after high school and Eric become a plumber after a career in the U.S. military. After working for other big plumbing companies, both of them knew there was a better way to meet San Antonio’s residential plumbing needs. With each now in the second decade of their plumbing careers, they established o5 together to serve customers with expertise, integrity and honesty.
