The wife of my next door n'bor died and his daughters got married, so he and his mil moved to an apartment instead of the townhouse.
The new tenant has an inflatable pool in the backyard, and it has a couple tan-colored plastic things with lots of little holes in one one of them. I can't see the other one well, but it's not shaped the same.
What are these things? They're connected to the bottom. But the pool is only 6 to 12 or 18" deep, so I don't think they are decompression devices.
Amazon photos so far don't show them.
The pool comes with an electric inflator.
