Plumbing Interview Question:

When I Run The CWM My Toilet Bubbles/Overflows or My Shower Overflows?

Submitted by: Administrator

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.
