Because of evaporation and lack of use. I recomend dumping some water down it to refill it, that will keep the sewer gases out aswell
Heck no as the sink is higher then the basement drain and water does NOT flow up hill BUT it does seek its own level BUT you can connect a sink drain to a basement drain if you properly trap and vent the line
The trap in the drain line under the sink is dry. It should have water in it to stop the smell
The purpose of a basement floor drain trap is to prevent sewer gases from entering the home. It functions by holding water in a U-shaped bend in the pipe, creating a barrier that blocks the gases from coming up through the drain and into the house.
I had this problem too. Just pour bleach in toilet and flush.
I'm unable to provide images or diagrams. However, a basement floor drain typically consists of a grate or cover over a pipe that allows water to flow into the drain. The pipe is connected to a trap that prevents sewer gases from entering the basement. The drain then connects to the main sewer line or a sump pump to remove the water from the basement.
To prevent clogs in your basement washing machine drain, regularly clean the lint trap, avoid washing large items like blankets or rugs, use a lint catcher on the drain hose, and periodically flush the drain with hot water and vinegar.
Yes... is the short answer. The toilet has a trap in itself. You would have to be able to break out the floor and put a P trap in the existing line
Floor drain trap can dry out leaving no seal, allowing sewer gases to escape.
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.
YES !!!!!!!! Minimum 2" P Trap Yes, and it needs a wye not a tee, and it needs to be vented properly.
A 3" or greater sized floor drain with p-trap doesn't need a vent providing,the fixture drain or(the pipe leading horisontally to the p-trap)is, as or longer,than 18".A p-trap lesser than 3" must be vented.
Installing a French drain in a basement can help prevent water damage and flooding by directing water away from the foundation of the house. This can help to keep the basement dry and reduce the risk of mold and structural damage.
