Hi
I installed a double bowl sink about 5 years ago.
A year or 2 in the bowl farthest from the trap had a rank odor, like something decaying.
It was detectable on the left but not as bad.
I will attach a pic for clarity.
The left bowl is closest to the trap.
The dishwasher hose has a loop/trap in it and it doesn't smell when you take a whiff inside so shouldn't be the DW.
The drain connection enters the cabinet about 6" to the left of the left hand sink through the back wall.
The left sink drain from the tailpiece takes a 90 straight back then 90 down into the top of a tee-wye and straight down to the trap.
The right sink takes a 90 straight back, then 90 left into the branch of the Tee-Wye with about 1/4" slope towards the trap.
When I installed the sink, I did this to create a little extra usable space, instead of connecting the 2 bowls directly inline.
I did take it apart once and there was some grease/gunk etc inside so I used my snake and cleaned out the inside which helped but not perfect.
Wondered if it could be siphoning the water out of the trap and what causes that? Although, the trap seems to have water in it when I disassembled it.
The drain runs back into the wall and down about 3ft then horizontally to the main 3".
The sink is used regularly so it's not an issue of the trap evaporating. It doesn't really smell like a stink pipe, more like rotting vegetables etc.
Thanks in advance for any input.
