    Venting exterior sink
    I bought a house that has a sink outside by the grille. The sink drains very slowly. There is no vent on the drain line. Would this cause the extremely slow draining?

    If so, can I add a vent inside the cabinet, under the counter top?

    Yes, You can cut in a tee after the trap and just run a "local vent" up the wall -OR- you may add a AAV,(Air Admittance Valve) cheater vent,(see image) just after the trap. Both Studor and Oatey sell AAVs You may put those names into a search engine to find out more about them. Good luck, Tom
