Just installed a Sure Vent underneath our kitchen island sink. I added the T and 5-6 inch of pipe between the T and the sure vent.

Now water is filling up the sink and the sure vent pipe.

What did I do wrong?

  • Did you stuff a rag in the pipe to prevent smells or possibly dribbled some pipe cement in the drain and it spread over the water in the trap made a plastic plug I have seen that before.

    The sanitary Tee in your photo is installed UPSIDE DOWN. The curve should be going down to drain, not up to vent.

  • @alaskaman I didn't realize there was a side to install it. Do you think it's worth redoing it? Seems to work fine now but ...

The actual issue was the drain blocked. The Surevent was properly installed and just exposed even further the fact that our drain was clogged. A full bottle Drano and a few dead dolphins later we are good to go.
