Only if you want to smell the fumes all the time. Code says it should be through the roof or above the edge of the roof.

Depending on which code your using, I normally vent a trap with in 2 ft of the fixture and I place the trap no further then 2 ft from the fixture EXCEPT for floor drain as I can install them with in 15 ft of a vented line

The trap should be before the vent. The trap is used to maintain a watter barrier to prevent waste water and sewer gasses from entering the home. The vent is use after the trap to allow the water to flow freely in the pipe with out drawing the water from the trap.


Why would there be a sewer gas smell in the basement landing whenever the downstairs toilet which backs up to landing the is flushed?

If there's a basement floor drain close by, sometimes the all the water can evaporate out of the trap. This can allow sewer smells into the house. Just run some water thruough the floor drain to fill the trap back up. Ditto for any drain that doesn't get used very often. More input from FAQ Farmers: * Maybe the vent in the wall isn't connected properly or came apart. I would think you'd have a sewer smell all the time but maybe it just gets bad enough when things get stirred up to notice. * Vent pipes are a major source of sewer odors. Vent pipe filters eliminate these odors while removing greenhouse gases. Used zeocarbon is then put back into the soil.


Sewer smell in the basement when it rains?

Could be caused by a couple of things. If you have an onsite septic system (tank and drain field) the tank may be full, and the rainwater is causing it's contents to backup the main drain back in to the house. A vent pipe could be plugged, which causes the sewer gas to back up. If you are hooked to a public sewer, there may be a blockage in the main drain out to the line in the street. Have a plumbing contractor check it out. It can be very dangerous.
