What is P-Trap in Water Closets?
It is the shape of the drain. Lay a P down with the curve down and that is the basic shape of the drain. This keeps water in the loop if the P to make a seal against sewer gas coming back up.

What is a plumbing trap?
When the pipe goes down, and back up, and back down again, the first "up-curve" is called the trap because when the water goes down the drain, not all of it goes back up and down again (thanks to gravity). So there is a little bit of water there and it prevents any gas/odors from coming back up the sewer pipe. Provided that the pressure on the sewer-side of the trap does not exceed atmospheric pressure on the drain-side, the water will not get forced back up. Provided that the water is not allowed to evaporate, there will always be water there. And provided that there is enough water such that the top of the inside curve of the up-turn is lower than the top of the trapped water level, the trapped water will seal out the sewer gas.
What causes sewer smell when air conditioner kicks on?
It could be that the condesate drain line has been connected to the wastewater/blackwater stack. The trap (hopefully installed) preventing sewer gas from moving up the condensate line may have dried out. If dry, sewer gasses are no longer blocked by the hydraulic seal... resulting in a nasty smell when the unit is turned on and the fan kicks in. Just a thought.
How do you identify a sewer gas smell in basement bathroom?
Most likely a drain has dried out and there is no water in the trap to stop the gas from coming up. Sink, shower, or main floor drain.
Can sewer gas that is coming from a backed up drain be dangerous to a baby?
Yes, if sewer gas is coming into your home from a backed up drain it can be very harmful to a baby and everyone else inside the home. It can cause hydrogen sulfide poisoning and asphyxiation.
Can a toilet be removed and the waste pipe be converted to a drain?
You could do that but you would need a trap to stop sewer gas from coming in. The toilet has the trap integrated into it. If you have access to underneath then you could add one.
Is the sewer gas coming from your drain dangerous?
Yes and it can cause headaches, cancer, and other health problems such as breathing and such!
What would cause a sewage smell to come from your bathtub shower after it is used if there is a septic tank?
check or have a plumber check p trap in drain line under shower. if leaking [losing water] it wont stop sewer gas from coming up the drain. probably the most likely cause.
What would cause a very strange odor coming from a shower drain?
sewer gas. either your trap has run dry from lack of use or is improperly or not vented causing your line to syphone. this will cause the water in the p-trap to syphone out allowing the sewer gas to ecsape.
How do you stop sewer gas coming to the shower?
A p-trap installed under the drain stops the sewer smell, unlees the piping is S-trapped. This makes the water from the p-trap get suctioned out by the velocity and grade of the drain.When the water in the trap portion of your drain evaporates, this removes the natural water seal and opens your home to disease carrying bugs and sewage gas smell. H2GOFlo and the theInterceptor-Plus replenishes this water periodically, creating the required barrier, that blocks off the back flow from the sewer system from having direct access into your home.

What would cause a sulfur smell in the hot water when the cold water does not smell?
It is probably sewer gas or something coming up from the drain.
Where can the sewer gas smell come from if it does not come from the drain of the ower- level on-a-slab shower?
One of the biggest culprits I have found for sewer gas smell is the floor drain many floor drains are seldom if ever used and if unused long enough the water in the trap will evaporate allowing sewer gas to enter the dwelling. this also applies to any trap which is not used regularly.
What could be wrong if there is a strong sewer gas smell whenever any of the faucets or shower is running and the water pressure has decreased significantly?
Is there a floor drain or any other drain nearby that is not used often? Sometimes the p-trap in a drain will dry out and allow sewer gas to escape. The smell becomes more intense when hot water goes down the drain.
Why would sewer gas smells start after an inexplicable leak under the utility sink in the basement which is now dry?
The trap in the drain line under the sink is dry. It should have water in it to stop the smell
