In the deep end, I have three separate 2" pipe ends that are covered by standard drain covers. When the pool was emptied for a replaster, the drain covers were removed. Two of the drain covers were for the typical set of two 2" pvc pipe drain lines. But a nearby third one was capped off (inside threaded cap with the square male socket on top). Anyone know what that is? I would think that if it was or meant to be bypassed by the original PB, it would have been gunnited or plastered over.
My replaster PB thought it might be a pipe that runs straight down for some hydrostatic, water table reasons. I was thinking its a backup drain line, tho I see no evidence of a capped pipe sticking up out of the ground at my equipment pad area.
Anyway, just curious to know why its there and/or what function it might serve.
