K when we remodelled kitchen I installed a sink - similar design as previous so nothing really changed...
1. dual sink with disposal on the right
2. it is deeper
3. it is a granite sink to replace a steel sink.
4. house is 1992 - so it does have the vent on the roof.
5. traps appear clear.
6. even had septic looked at and emptied (it was time anyhow)
the side that has the problem is the disposal side. I've tried various suggested tricks off the web.
a. arm and hammer - and salt
b. gel drain cleaner
c. vinegar
(not all at the same time)
the top of the vent appears clear - cannot say if it's clear all the way down tho - need a huuuge ladder to get up to that side.
From my experience, a stink is usually caused by a problem with the trap. If the trap is a) in the right place in the pipe-line and b) has enough clean(ish) water in it, then the stink from the rest of the drain line will not intrude past it.
Is it possible that when replacing your sink, you threw off the angle of the pipes to- or from- the trap, causing it to not hold enough water? If there is now an air-space at the top of your trap, it can let in the stink from the drain line.
With the vent line going through your roof, I can't see that causing any smell, but I could be wrong I suppose - I'm a plumber only when needed around the house, not by trade ;-)
Due to the new depth of the sink I'm certain now this might be a yes - I'll check the angle of the trap - what would be my fix if the angle cannot change? can I get a deeper trap?
I think Zoo is on the right path, and I'm not a plumber either. One of the things I did regularly when I had a disposal was to do an almost final grind with lemon chunks, leaving just a small amount in the bottom of the disposal for a fresh smell... but it was not really because of a stink problem.
You should be able to make a deeper trap by adding a section of pipe.
You said the new sink is deeper - which means the 'incoming' side of the trap is probably too low. IIRC, most traps are 2 pieces - 1 U shaped 'trap' part, then a 90 angle off of there that leads to the drain line. You should be able to separate it there and add a small section of pipe to make the trap deeper and put the angle back closer to what it was.
Alternately, if you can reach the 'down' leg of the drain line, you can cut a piece out to make it shorter- but that part is usually in the wall.
