In water-starved California, pool repairman Kevin Wallace might be viewed as a hero in a scuba suit.
The 63-year-old Wallace dives underwater in some of the best pools in Southern California to fix rust spots, rebar, structural cracks and drains, using a secret concoction of plaster-based compounds, sterilizing agents and hardeners. The mixture seals within an hour.
The best part? No draining of the pool is required.
That's music to the ears of Wallace's clients, who include homeowners, big businesses and public agencies like school districts.
