kccandfc Posted March 31, 2009 Report Share Posted March 31, 2009 Attached is picture of a charred dialectic union. I noted carbon debris and rusting on top of water heater and attributed this back drafting. Is the charring a sign of back-draft or another issue?

kurt Posted March 31, 2009 Report Share Posted March 31, 2009 That be backdraftin', mate. It's not "charring"; charring is reducing something to carbon or charcoal through incomplete combustion. That's just plain old rust and corrosion, caused by the corrosive moisture (I think it's the sulfur dioxide) in the combustion gas. Quote Link to comment Share on other sites More sharing options...
SonOfSwamp Posted March 31, 2009 Report Share Posted March 31, 2009 Just to keep things tidy and sensible: Dialectic. 1. of, pertaining to, or of the nature of logical argumentation. Dielectric. 1. a nonconducting substance; insulator. Because discriminating customers expect us to know the difference between logic and insulation, WJ Quote Link to comment Share on other sites More sharing options...
