    Help identify a valve

    Can someone help me identify what the circled valve in the attached diagram does? I bought this home a year ago and can't determine the purpose of theis valve. Thanks in advance.

    It has to be a suction port somewhere in the pool. Look for a wall suction somewhere.

    That's very strange. If there wasn't already a "pool vacuum" port identified already, a wall suction vacuum connection would be what I would guess. But one of the valves clearly says "pool vacuum" already.

    Any chance it goes to the main drain?

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.
    A pool is like a pet - you have to feed it every day, even the days you don't want to play with it!
