Is this a side wall suction port or something else?

Hi TFP Community,

I am wondering if anyone may know what this capped hole is on the side of my pool. I thought maybe it was a side wall suction port for a suction cleaner, but when I uncapped it I feel no suction on it. I tested each one of my intake/drain lines separately with the pump on high to see if I felt any suction. I wanted to see if it was maybe reliant on it being on high with only 1 port open or something. No dice either. I opened up all of my working returns/jets and nothing was coming out of that either. I do have a non-functional spa pump with 4 returns in the spa attached to it, but this hole is in the main pool. The only thing I can think of at this point is that this hole is somehow connected to that non-functioning spa pump circuit as well or it's a clogged side suction port.

Any thoughts?

Thanks

It is probably a cleaner port or was one at one time. It may have been abandoned or perhaps there is a valve somewhere that controls it.

Don't open it out curiosity. In case there water in there that may be algae infested. If it's not bothering you let live.

Thank you for the response. That's pretty much what I've come to as well. Unfortunately all the valves I can find are accounted for. Oh well lol.

If it was a suction port for a cleaner it was probably powered by a booster pump. If you have no obvious spot on your equipment pad where a pump may have been, the other possibility is that it was a leaky return line that has been capped off.
