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:
Could it be the disposal? We have tried a plunger, draino and some special disposal cleaner all to no avail.
Thanks for any advice!!
