Why does my bathroom drain make a gurgling noise?
A blocked or improperly-vented drain needs to be repaired, preferably before there is an unsanitary sewage backup in the building. Gurgling drains can be fatally unsafe if the loss of water from a plumbing trap (due to inadequate venting) permits sewer gases to enter the building. Sewer gases contain explosive methane. McGeehan, Patrick.
What to do if you hear a gurgling sound in Your House?
Look in the attic for a plumbing drain line that passes vertically up from the floors below and out through the roof. If you can’t find one, the building may not have proper plumbing vents. Look outside for plumbing vent pipes poking up through the roof in one or more areas.

Why is there so much noise in my plumbing?
Apart from trapped air, noisy plumbing can be caused by a phenomenon known as water hammer. If you close a faucet quickly and hear a loud bang followed by repetitive but diminishing banging noises, it’s probably water hammer or “hydrostatic shock.” The weight of water rushing through pipes generates high velocity and momentum.
But in a more modern structure that uses plastic or copper drain piping these materials can transmit the sound of running water to the building interior. Builders can reduce sound transmission from plumbing lines by enclosing them in insulated chaseways.
What causes a hissing sound in a plumbing line?
The disrupted flow of water is caused by air in the line, i.e. air that is trapped inside the plumbing lines. Water flow impaired by air in the line is often described as having a ‘hissing’ or ‘hammering’ sound.
What makes the most noise in a bathroom?
Because bathrooms typically contain large areas of hard materials like tile and parallel walls, sound waves tend to “bounce around” the room. Lower, or bass sounds tend to be the most difficult to control as they resonate more off of large flat surfaces like walls and floors.
