I installed a new garbage disposal today. Here is a photo of the plumbing:
It seems like there is some sewage/sewer smell coming from the garbage disposal, as though the P-trap were missing (which it is not).
Is the plumbing suitable?
I did notice that the dishwasher drain hose smelled pretty bad when I took it off the old garbage disposal. I do think the foul smell could be coming from that, so I plan on changing the hose tomorrow. But, I wanted to ask the pros here if the other plumbing was okay. (And yes, I do have a stopper on top of the garbage disposal strainer for the time being.)
Edit: My sink has an air gap, and the hoses are connected to it properly (one from dishwasher to air gap, and another from air gap to garbage disposal).
Edit: So, I did three things: (1) slowly ran water faucet to fill the P-trap, as perhaps the P-trap was not absolutely full for some reason (I ran the water a lot since replacing garbage disposal, so not sure why it would not have been full); (2) poured some bleach down air gap; I made sure it went to the hole that goes to the garbage disposal; and (3) ran dishwasher on sani clean cycle.
Smell seems to have gone away now.
