Help with sink filling
The past few weeks, our kitchen sink started draining slowly and making a gurgling/gulping sound. Two days ago it stopped draining and the sinks started filling with water. It’s a double sink with a disposal on one side and sink basin on the other. If I turn the disposal on while both sinks have water, it will empty the disposal side, fill right back up and cause a gush of water in the other sink basin. I have taken apart both p traps which were clear and opened the clean out valve and snaked about 15 feet down and found no clog. Could this be an issue with venting and not getting enough air? I haven’t had the issue in any other sinks or toilets. Just the kitchen area. I attached a pic of the under sink plumbing. Any suggestions? Thanks
