We have a double sink. When we run water down the disposal side dirty water
comes up into the other sink. We have plunged both sides. Any help would
be much appreciated.

You have a clog somewhere past where the sink drains connect
together. To plunge properly you need to stop up the other drain.
Easier with 2 people so one can keep whatever you put in the other
drain down tight.

I have brought in a garden hose with a squeeze handle on it. Have one
person hold down the plug on the disposal side. Maybe even fill that sink
half full. Put rags around the disposal side to hold the seal on the hose.
Fill that half full also. Hit it with bursts of water. Watch underneath
because if the pipes are not tight, or they don't penetrate into the collar
far enough, they will blow off, and you'll have a mess. Tighten them first
WITH YOUR HANDS, NOTHING ELSE, as they are mostly plastic.

Let us know what works for you.

Do you have a dishwasher and sink mounted vent pipe attached to the
disposal?

Is this a new install? Depending on the install directions, sometimes
you have to knock a plug out so things vent and water drains. I
learned about this "knock-out" piece after the dishwasher backed up
into both sinks. Lucky it was a 15 minute fix..
