I have 30 years of experience in the field of plumbing, with specific knowledge of hot water systems, scalds, product failures, injuries, water damage and fuel gas systems, explosions and fires. I have published on such topics as plumbing codes, product standards and plumbing system design. I have testified 20 times on topics such as plumbing design and installation errors that led to scald burns, plumbing product defects, personal injury and property damage related to plumbing, and mechanical and fire protection systems.
