What is this fitting for?

This was installed but PB. I have no idea what it does or what it's for but I am hoping it is something to do with ground water removal? I recently posted a thread about my pool vinyl liner floating. PB came out and pumped ground water out from behind liner. We had a few wrinkles left on the bottom that I just could not overlook. About 10 days later they came out and got the wrinkles out via draining into bladders. The guys that did the work said there was no more water behind the liner and questioned what this "capped fitting" was for. They thought it perhaps was something for ground water removal, maybe?? *fingers crossed*. This is not for water feature, I have that, the plumbing for it is just not in the picture.

Are you asking about the capped off pipe on the far left?

My guess would be a spare line that could be used for a dedicated vacuum cleaner.

Yes the capped fitting on the far left. I don't think its for vacuum as I have a booster pump and associated piping for side wall cleaner

g,

You need to ask your pool builder... All we can do is guess..

I suspect you are correct in thinking it is a drain point, but we have no way to tell for sure.

Thanks,

That’s certainly a creative manifold.

Under-pool/dewatering/remediater / well point/mudsucker - or whatever they are called in your region
that’s where I place my bet.

Yes I heard back from the PB and they said during construction there was ground water. They installed this line to pump it out. Kind of like a French drain. Hmmm, in RARE cases as during a hurricane I wonder if I can use this to remove ground water before floating occurs. PB said they used a diaphragm pump.

Our pool guy reccomends draining every other month or so to keep the ground water down. Definitely before a storm! We connect 1hp motor and it drains for days.
Commonly called a well point around here.
