Why Does My Toilet Smell Like Sulfur?

The vent stack is the main air circulator plumbing network- that maintains the air pressure and circulation of all faucets in your house.
A vent pipe is installed to allow the waste air or sewage air to pass easily through the vent stack and prevent the odor from coming back.
Many circumstances, like cyclones, high winds blowing, dust, bird nests, snowfall, etc, can block the vent pipe that runs through the roof.
Any object stuck in the vent pipe causes blockage and prevents the airflow, so the waste air that is going up returns to the faucets and creates a foul odor.
A clogged vent pipe eventually causes a toilet to overflow.

typically installs to prevent waste smell and air pressure. P trap almost works like a vent pipe but inside the house.
P-trap maintains an amount of water seal inside the P-bends. If you notice there is an extra plumbing system present below the sink, that P-trap.

To equalize the pressure, the air is drawn in from an outside vent while the water drains through the P-trap.
Heavy rain or snowfall, on the other hand, may impede the vent, causing the P trap seal to be pulled out by the flowing water.
You may notice a gurgling sound as air is pulled into the drainpipe, and you may smell like rotten eggs coming from that sink during this period.
The vacuum in the system will suck air from other drainage fittings if it doesn’t have exposure to the outside air.
If you stench sulfur smells after flushing the sink, it might be an indication of a bigger airing problem. Because flushing the toilet also dries out the water from the P trap at the same time.
An accumulation of trash might also cause problems. Due to capillary action induced by coils of fabric and hair along the pipe, water may eventually leak out of the P trap and cause the sewage odor release.
That’s why it’s essential to keep debris out of the P-trap.
