Bob meets up with plumber Ted Moxham and Kinetico rep Dave Krupinski in the basement where Ted is installing a Kinetico water purification system. 85% of all homes in America have hard water, so even though the Medford house has processed city water, it's still important to treat both the hardness and the chlorine content. Chlorine can dry hair and skin and prematurely fade clothes. The Kinetico system can solve the problem of sediment buildup in the pipes. Over time calcium from hard water scales inside the pipe significantly reducing plumbing size and thus lowering water volume throughout the house. This same clogging can also occur inside water-using appliances reducing their efficiency and causing unnecessary repairs. Kinetico's two component whole house water management system can effectively treat these problems. It has a dechlorinator and softener that treats the general purpose water that flows throughout the house and a reverse osmosis multi-stage filtration system that further purifies your drinking water. The water softener uses a regenerant salt that cleans the tank of any residue hardness and then flushes it down the drain. The Medford system also features Kinetico's new Quick Flo tank which speeds up the delivering of water through the reverse osmosis filter Regular maintenance includes periodically putting salt into the system and replacing the pre-filter and the pulse filter on the reverse osmosis system annually.

Bob meets with Neil Sugarman to check out the water conditioning system and then goes on a tour of the Kinetico plant in Cleveland to see how the water conditioning system is made.

Bob visits the historic neighborhoods and parks of St. Petersburg, Florida, starting with Roser Park, known as "the neighborhood a cookie built" because its founder, Charlie Roser, had sold his company Fig Newton to the National Biscuit Company before developing Roser Park in the early teens. In the 1920s Roser Park was considered one of the most attractive residential developments in all of Florida. Many of the historic buildings are still standing and brick walkwaysbuilt of Augusta block line Booker creek. The Old Southeast development was built a little later and boasts Lansing Park on Tampa Bay. This is a purely residential park designed for fishing and recreation, but sitting only a few miles from the high-rises of downtown St Petersburg where Bob points out the Salvador Dali museum, big businesses, colorful restaurants, an open-air post office designed by Edward Tomlinson, St Peters Episcopal church, and The Coliseum. Old Northeast neighborhood encompasses Crescent Lake Park and boasts an eclectic mix of historic building styles from around the country, including bungalows, Colonials, Federal Revivals, Mediterranean villas, Florida crackers, and Prairie-style homes. The North Shore features parks with public access to the water and high property values. To the north of St.Petersburg lies Snell Isle, developed by C. Perry Snell with the intention of producing a truly upscale residential area. It features statues imported from Europe and beautiful large homes.

Back in the basement, Bob explains how the Kinetico water purification system works. The system uses kinetic energy created by the flow of the water itself to filter out minerals, such as iron oxide, calcium and magnesium that produce hard water. The system has two purification tanks with one working while the other is cleansing itself. The tanks are filled with resin beads that attract mineral particles. When the beads are full, they are recharged with sodium ions and the minerals are washed out of the system. The second part of the system deals with eliminating arsenic content and other mineral particles from drinking and cooking water. First the water is filtered to remove sediment and particulate that may have made it through. Then the reverse osmosis filter gets rid of miniscule remaining particles and trace elements. The water then passes to a storage tank where it circulates until it is needed in the kitchen. On demand, it passes through a carbon filter to eliminate any unpleasant tastes that might still remain.
