I have a sulphur smell in my basement which I think is from the drain tile under the floor. I have a sump pit and the odor comes from there... its been dry and odorless from the pit for weeks and then after a recent rain... water (and the odor) has begun.
I have scrubbed and cleaned the pit itself. Even after that if you put your nose down there its obvious the smell is coming from the inlet pipe I presume. A laundry sink connects to the pit too. Laundry and softener discharge goes into it as well... so I don't know if I am smelling something as a result of that or if its the ground water that I am smelling. There are no traps in basement connected to the sewer.
The water running into the pit is clear, however, when I flushed out the line from the laundry sink with a high pressure nozzle I was getting lots of blackish water running into the pit which after awhile it to began running clear. Im not sure what to make of this.
How do I go about trying to rectify this?

Putrified laundry drain water can be one of the worst smells and is probably your source of odor.

After a day when their is no trickling into the pit the odor stops. It can stay like that for days/months. However, once it starts raining and water is flowing into the pit at a more consistent basis the odor starts. That's why I don't know if its the pipe I am a smelling or the water itself.
The floor drains in the basement lead to the pit, I flushed them with a hose for almost an hour... is there something I can do further in that regard?
I have a slotted cover for the basin. If I seal it tight I have learned I will need to vent it. What size hole/vent is needed? I dont want to add a pipe to the outdoors and if I simply vent it to the open space in the same room, would that defeat the purpose of sealing it up?

Doesn't need to be vented. You don't want it vented because ground gases, odors and radon.
