How do I unclog my double kitchen sink when the disposal shoots water back up into both sinks?
I have a major problem with my kitchen sink. It’s a double sink and on one side there’s a disposal. The other side doesn’t have a disposal. Both sides do not drain at all - unless I plunge the heck out of them. When I do run the disposal, the disposal side of the sink drains the water, but then it shoots right up into the second sink. After turning off the disposal, both sides become overflowed again. I’ve tried the liquid plummer, etc. stuff and my husband tried to snake it. What to do?

turn you water off and have your hubbie (or you can too) undo the pipes under the sink. Sounds like something is catching in the draining pipes. It will be REALLY messy when you undo the pipes but it may help the problem.
You can try taking off the trap and running a snake through it. If that does not work, go to the basement. In the area under the sink, look for a drain pipe with a clean out nut on it. un ***** that and try snaking from there.
use a short bowl or bucket under the trap to catch water and debris, unscrew trap connections first, then the rest of the drain plumbing. my guess is there’s buildup in the trap both sinks and the disposal drain into. it will stink, and be plenty nasty, so rubber gloves are a good option. take all drain plumbing pipes outside and spray them out with your garden hose. reconnect, and fill each side of the sink seperately and let drain. if this dosent work, disconnect pipe that runs back into the drainpipe in the wall and snake it as far as you can. still stumped? call a plumber.
Sounds like the problem is in the pipe that they both drain into. I’m not a plumber but what has worked for me is stopping one up tight, then using the plunger on the other side, that way, the pressure can’t just go to the other drain. Hope it helps!
