Laundry room p-trap:
1. After washing, the p-trap is definitely filled. I have a cheapo USB sewer cam to confirm.
2. Within a few days--usually 4, the trap is dry enough to let fumes into the laundry room. This seems way too short, yes?
3. I'm tried flushing the nearest toilet to see if it is siphoning the laundry room trap. It isn't.
4. There is a vent. The vent appears to be clear--I didn't snake it but I did run a garden hose down it full blast from the roof.
5. The trap isn't leaking--I have the dry wall removed on the other side of the wall.
So....any other ideas besides the usual above? This is baffling me.
Thank you.
