Solar Water Heating; Electrical Safety Devices; Support Posts

Plumbing and heating expert Richard Trethewey heads to Salt Lake City, Utah, where he and a local contractor install a new solar water heating system. Then, up in the workshop, electrician Scott Caron shows host Kevin O'Connor a few devices designed to make residential electrical systems safer. Then, Kevin and general contractor Tom Silva head outside to replace the rotting support posts underneath a backyard deck.
