Richard Trethewey, the plumbing and heating specialist, teams up with host Kevin O'Connor to swap out an outdated tank water heater for a modern, energy-efficient tankless model powered by propane. Later, Richard, Kevin, landscaping expert Roger Cook, and general contractor Tom Silva explore the question, "What is it?" Meanwhile, Roger assists a homeowner in leveling a sunken concrete walkway using a technique known as "mudjacking."
