    Water Supply Main Shutoff Valve installation
    The 2006 International Residential Code, P2903.9.1, Service Valve, States that the valve shall be of a full open type having nominal restriction to flow with provision for drainage such as a bleed orifice or installation of a separate drain valve. How are the plumbing experts handling the waste from the drain valve in a finished wall with an 10 X 10 access door? Is there a readily available valve that allows a hose attachment to the waste drain of the shutoff valve to avoid flooding the wall cavity and subsequently ruining the finished wall board from the drained water? Are the plumbing inspectors enforcing this code in your area? Are they allowing the valve with provision for drainage without a means to direct the drained water? Thanks in advance for your answers.

    If you notice the waste drain can be pointed to a better place.

    I agree, that in certain instances, like yours, it would be extremely nice to be able to direct the vent port.

    It does say in your quote that an "installation of a separate drain valve" is permissible.

    I did not find anything that I could connect to the port, so I silver soldered a piece of brass pipe to a modified cap. I attached a small valve to a piece of plastic tubing.

    This I've used for many years at home to drain an outdoor hose bib for the winter with a very complex connection. Now it's a simple process.

    In order for what you need to work, you need exactly the setup I created. I do like your idea, though.

    Raonoke: You are correct. Code constantly changes and we, as contractors, are not updated on Code changes as they take place. We only find out when inspector shows up for final inspection and disapproves the installation based on new Code.
