Synopsis

Plumbing and heating specialist Richard Trethewey guides a homeowner through the installation of a new, water-conserving "dual flush" toilet. Afterward, Trethewey joins host Kevin O'Connor, landscaping contractor Roger Cook, and general contractor Tom Silva as they pose the question: "What is it?" The team then moves outdoors to demonstrate the installation of an in-ground sprinkler system, a project accessible to homeowners of all skill levels.
