Plumbing Alamo - How to get rid of a Bad Smell - Guaranteed Plumbing Co

It is a plumbing ventilation problem.

Plumbing works on gravity, water runs downward and air runs upward. Water and air cannot function separately in pipes. They need to work simultaneously.

In other words, if air is not escaping upwards through your pipes and out through your roof, water will not travel downwards causing all kinds of problems, such as back up flooding and foul air escaping through your home's interior exits (sink/bathtub drains).
How to Fix a Plumbing Ventilation Problem:
1. Clean out ALL of your "P Traps" (the rounded pipe under your interior drains). This will cost you nothing if done properly.
2. If you don't have "P Traps" because of the age of your home, it's time to upgrade. Install "P Traps" everywhere needed. Consult a professional plumber, if needed.
3. If that doesn't stop the problem, you may need a "Total Air Line Flush." Consult a professional plumber.
4. If that doesn't work, you may need to install "Backflow Preventers" in ALL your drain pipes.
