Hi,

I am having a little issue and would appreciate your advice.

I own a condo with a double-sink kitchen.
My problem is that soon after we've done the dishes, the sink will gurgle and soap suds will back up into both sinks. It's only suds, no water and no smell.

There are no draining problems. The water flows just fine.
I tried Draino but that did not help. I doubt this is a pipe clog issue.

I saw on this site that an inline vent may help. Do you think this is worth a try?

Thank you!

You don't have a full clog but I bettcha you have a partial blockage that's producing backpressure that will cause those bubbles. Backpressure will produce bubbles while a clogged vent will attempt to vent through the trap and you will hear gurgles but not see any bubbles.
The solution,(before it gets worse) would be to remove the "J"bend from the trap and run a 3/8ths. Inch snake up into the wall,(see image). You will hit a bend about 8 inches in but once around that you should have only 5 or 6 more feet of snake to put in. After, flush the line with a tub full of hot water. Good luck, Tom

Thank you. I will try this out.
