Plumber Interview Question:

Tell me when I Run The CWM My Toilet Bubbles/Overflows or My Shower Overflows?

Submitted by: Muhammad

When the lowest plumbing fixture in the house overflows when another fixture (like a CWM) is draining; the septic tank needs to be pumped, there is a break in the sewer pipe outside the house or the main drain is plugged somewhere.
