Seeing is believing. How does sewer gas enter the home when an "S" trap is used? Why does the TPR valve drip on some water heaters and how does an expansion tank stop it? Using an animated slideshow, classroom demonstrations and video of field demonstrations, Kenny shows what happens when plumbing systems and devices fail. Come early and sit up front. The videos and animated slideshow are fun. The classroom demonstrations are a blast! *Florida students: Upon successful completion of modules, email certificate of completion to ASHI Education at education@ashi.org. Credits will be filed electronically to FL by ASHI.  FL #1165;
