    I successfully installed a new kitchen faucet today, and for good measure replaced the airgap.

    I thought I had done everything right but when I ran the dishwasher, during the rinse cycle water started pouring out of the gap vent. I could see that some water was properly draining into the disposer, however. But there was enough water coming up through the vent cap to make a mess. The water was hot and clean.

    Below the sink, the air gap has one stem going straight down which I connected with the existing hose to the disposer and a second stem coming off at an angle which I connected to smaller line running to the dishwasher.

    Any suggestions as to the cause? Thanks in advance for your help.

    air gap

    The most likely reasons are that you either bent the hose to the disposer, or the new air gap is longer so the hose to the disposer has a dip in it.

    Still leaking

    I carefully checked the hoses, no kinks. I even realigned the hoses slightly to minimize any bends from the gap to the disposer. It is still backing up through the vent. I then went and fished out the old air gap from the trash and reinstalled that model figuring going back to the way it was before would do it, or maybe I just had a bad product. Still, the water backed up.

    Time to call a professional - too bad something silly like this is the reason I call a plumber. If he laughs his a-- off at me, I'll deserve it. I'm about to turn my toolbox in.
