3-Hours-The Plumbing and HVAC Guy on Plumbing

This session includes hands-on items

During this presentation Kenny Hart will examine some of the piping materials seen by home inspectors in the field and he’ll do it from a plumber’s point of view. He will discuss how the material is installed, some common installation mistakes and failures, and speak on issues that a tradesperson might be more familiar with, than home inspectors.

The final part of the session will focus on water heaters. Storage tank and tankless water heaters are both covered. Recent changes in water heaters are reviewed. Kenny will wrap the water heater portion with a review of what inspectors should see when they inspect the TPR valve and common, sometimes dangerous, installation mistakes.

Christina El-Hage is the Vice President of Sales at Priddy Chimney Sweeps, a local family-owned sweep and masonry business based in Beltsville, Maryland.  Christina has been with the company for over eighteen years, starting out as an office manager.  From this role her responsibilities grew, as did her industry knowledge:  she was one of the industry’s first certified female sweeps, earning her certification from the Chimney Safety Institute of America in 2007. 

With a family background in masonry and construction, the job was a natural fit.  Christina’s grandfather was a mason based in Rochester, New York, in whose firm, now known as Taylor Builders, Christina worked summers.  It was here where she learned about masonry and construction best practices.  She uses this experience today to help solve complex venting, water and masonry issues for residential as well as commercial customers. 

Christina’s true passion is interior design, and she enjoys helping Priddy’s customers and architect partners realize their room concepts, both with and without fireplaces.  In her off-hours, she spends time at Bethany beach with family or exploring other parts of Maryland’s Eastern Shore.  She has a daughter, Paris, and currently lives in Silver Spring, Maryland.
