    It looks like the indexing valve for an in-floor pool cleaning system. Did you see pop-up spray heads on the floor of the pool?

    yes i did actually. How does that thing work? is it something that needs to be opened for cleaning? or is it being in the ground a problem?

    Yes, you need to be able to service the valve. There's a whole gaggle of parts in those valves, along with gaskets, o-rings, etc. As long as the top part of the valve is above ground, the internal mechanism is accessible for repair.

    As far as operation goes, there is a disc inside with 4, 5, or 6 ports depending on the model. A spring loaded rotator or gear driven assembly advances the active port to allow supply-side water to activate the pop-up cleaners on each zone. It works very similar to an irrigation system, including the indexing valve. And the floor heads need repair or replacement from time to time as well.

    That photo looks like one of the most common valves around Central Florida, here is a link:
