I recently replaced the kitchen sink in my mobile home. I since have water coming up through the air gap. What's my problem?

Check to make sure your hose from the airgap to the sink isn't crimped or clogged. Did you install a disposal? If you installed a disposal did you remove the knockout plug? Does the sink drain fine otherwise? Post back and let us know what you think. GOOD LUCK, AC

Please give us some more details, do you have dish washer and garbage dispsal,if you don't have a dish washer then you don't need an Air Gap, get back to us, Thanks.

I guess it would not hurt for you to tell us why you needed to replace the first air gap.
