My kitchen sink randomly regurgitates water and small particles of food in both sinks to overflowing. I have tried using a plunger in both sinks. I took the under-the-counter plumbing apart and snaked down 25 feet without an obstruction, cleaning the pipes before re-attaching them. Now what can I do to fix this problem?

Is there a vent? If there is no vent the water will gurgle and take a while to drain. If you do not have a vent you can install a pop up vent under the sink. What the vent does is allows air to come behind the water to push the water down.

Hello nel249,

You have a blockage in the vent check your roof their should be a vent pipe sticking up for the kitchen and you snake it from there to clear the blockage, good luck.
