Question

My disposer shoots back up through the left side drain of my two-bowl kitchen sink when opperated. I have twin drains that tee into one common p-trap. Should I be using two p-traps (one under each drain to prevent the disposer from shooting back to the other side?

Thanks

No, what you have is good. The one area you may want to check is the tee going to the G/D. Take this piece off and look into it, there should be a deflector inside that causes the water to shoot down. If you don't have this inside, just a normal tee than the water is able to shoot up into the sink. Replace the tee with one made for G/D and your problem should be resolved.

Thanks Trying2help! I didnt realize that they even made such a tee for G/D. Im sure mine is a normal tee since I just replaced the plastic piping to metal piping recently. I will see if I can find a metal deflector tee.

Thanks!

It doesn't have to be metal, they come in PVC too.
