Field ServiceDiagnostics & Troubleshooting5CriticalHomeowner$ explicit

Plumbing vents are not properly installed (capped and terminating in attic) causing severe drainage issues, backups, and gurgling throughout the house.

Plumbers performed isolated tests but failed to diagnose the root cause—improper venting—until the 4th plumber, and even then, the solution (opening vents into attic) worsened the problem because vents don't exit the roof.
