Today, I’m going to write about a plumbing issue that is as easy to diagnose as counting “1-2-3,” or—more aptly—“A-B-C.”

I’m talking about “S-traps” and “P-traps.”  If you don’t know what these are, this video gives a nice overview. After watching this, you’ll better understand why you may want to consider making the switch from “S” to “P” in your home’s sinks.

I recently came across this very issue during an inspection on Fidalgo Island, where I found an “S-Trap” installed under the kitchen sink. As a result, I recommended the homeowner install a “P-Trap” in my report.
