Why this site exists

Professional water-supply engineering and household plumbing share the same physics but rarely the same vocabulary. Homeowners searching for help with a frozen pipe, a failing water heater, or a slow drain land on pages that are either too shallow or written without regard for the codes and first principles that govern the system. MyPlumbingPal exists to close that gap: engineering analysis that is grounded in plumbing codes (IPC, UPC, and equivalents worldwide) and field practice drawn from experienced plumbers — cited, reviewed, and updated.

Where my authority stops

I am a civil engineer, not a licensed residential plumber. The guides on this site reference U.S. plumbing codes (International Plumbing Code, Uniform Plumbing Code) and their international equivalents — those references are cited, not claimed as trade experience. For any work that requires a permit, a pressure test signed off by a licensing authority, or contact with your sewer or gas lines, call a licensed plumber in your jurisdiction. The guidance here is a starting point for understanding the problem, not a substitute for a tradesperson on site.
