Two Story Dollhouse, Self-Paced Online

Tradesman and Journeyman plumbing applicants in Texas must design and install the Drain, Waste & Vent (DWV) system for a two story miniature structure (residential for Tradesman, commercial for Journeyman) known as the “dollhouse.”  This course is an optional tool to prepare for that portion of the Texas Tradesman or Journeyman plumbing exams.
