Kitchen Plumbing Drainage Configuration
The piping under the kitchen sink seems to be less than effective. I’ve attached photos & would appreciate suggestions on how I can reconfigure. Thanks
arch not sure if it is your pictures or your drainage pipes are not sloping the right way. It appears as if your drain goes into the garbage disposal. You’d have to get that fixed for sure. Also, it looks like you are having some vent issues. Hard to see, but can you ty to tell us what the last component next to the wall is It does look like some kind of vent….
I have the same problem, can someone recommend me a good plumber. I'm tired of searching by my own
This is about as optimal as you can get. Everything is draining down. The possible exception is the disposer, the black pipe out of it seems about a 2 cm too long. Remove the connection and hacksaw off a bit and replace the connection.
Looking at that I would definitely recommend having it looked at by professionals. The biggest example that I have to give you is of me and my friend that both had a water leakage in the bathroom around the same time and I chose to have a team come and do a water pipe leakage repair, while he DIY-ed the entire thing and had it blow up in about a month. It definitely cost him a lot more than it did me because he had to change a lot more pipes after that.
@arch It looks like whoever did this wanted only one p-trap but clearly didn’t install it properly. Also since there was no external venting available, they used an internal air admittance valve which is not a problem but it does require you to check it's functionality occasionally as that could also be a culprit (if everything seemed to work well before).
Example of how it works:

Lastly, you know as everyone has told you, that slope is WAY wrong. Here is a sample photo of what it "should" look like:
