Help with Kitchen Drain

Hello. Got a kitchen drain issue and I was hoping for some advise. I have a double sink, disposer on the left, rinse sink on the right. We have been experiencing slow draining on the disposal side and it especially sucks when washes pots and stuff on that side. As it backs up, if I turn on the disposal and pushes it right through. I was told by a neighbor that the drain from the disposal to the trap may be clogged or that it needs more of a down angle. I took a picture here:

It ain't clogged. I do notice the the drain from the disposal is going down, but that the hole assembly on that side is lower than the main drain into the wall. Is this OK? It is kinda hard to see in the picture. To move the "T" up above the main drain would require the disposal to drain "up" into the "T" and this doesn't sound right either. The right side that goes straight into the trap drains fine.

Could it be the disposal? We have tried a plunger, draino and some special disposal cleaner all to no avail.

Thanks for any advice!!

As long as the disposal outlet is a hair above the wall exit, it should work, but it's not the best arrangement. To really fix it you'd have to lower the wall exit point.

The TEE likely has a "baffle" built in. That can restrict flow by quite a lot. You could experiment by sawing the baffle out, but with this arrangement you may get water from the right side backing into the disposal.

A lot of work, but you could put 2 traps in, with a WYE at the wall. That would/should help the flow a lot.

Could be that the "graters" on the side wall of the disposer are partially clogged from waste build-up. Something easy to try -- turn on the disposer and with the water running feed in a bunch of ice cubes. I usually run an entire bin of ice through.

Disposals need a nice smooth slightly downhill outlet to a wye drain fitting. That's not what you have. Seems to me your plumbing system needs to be redone by someone with more tools in his bag than a hacksaw and a screwdriver. This project would benefit from some professional help at best, or highy skilled DIY at the least. Good luck.

I did that once and it broke through the outer shell of the disposer. Water went everywhere. Had to install a new disposer. Grind the ice up first.

If it has worked in the past and this is a recent development, then you should not have to change any of the plumbing. Have you taken the drain apart? You've got some threaded connections there that would be easy to take off and inspect for large clogs. The ice idea is good to help unclog, but sometimes, with things like chicken skin, it still won't help unclog it.
