Effective September 2007, the Texas State Legislature enacted into the Plumbing License Law additional wording to specifically include water heaters in their list of plumbing fixtures, required by law, to have a plumbing permit issued prior to installation. In addition, the law provides that such installations be done according to current codes by a Lucas TX licensed water heater technician and inspected by a licensed plumbing inspector.
