What do you think this open vertical pipe is for?

I bought the house with this pool a couple of years ago. I've figured out most of the plumbing by now but this open vertical pipe (the one in the front of the pic with two right angle corners attached to the top) continues to confuse me.

Is it a vent? Why would that be needed?

Is there a chance it is a connection to the main sewer line for disposing of backwash?

Or maybe it is a return line for a missing DE backwash filter to the main pool?

I have no idea.

Spa?

Spa?

Yes there is a hot tub, and it's elevated, probably about the height of this pipe. How would they be related?

It is the air inlet to the Hartford loop. When you run the spa, at elevated rpm, does air come out of the jets ?

... and do you feel suction at that open pipe when the spa is runnning with jets on?

The air intake should be pointed down, so stuff won't fall into it. Hopefully it's not glued and you can simply rotate it.

That makes sense. Have not run the spa jets yet - the pump for that line is busted and needs replaced, as does the water heater that would make the spa useful.

You have alot of pumps. I suspect you could replace some if not all with a single VS pump and some plumbing modification.

You are not wrong! Some of them are for simple water features which does seem like overkill. Also when more than one is running at the same time the noise gets pretty bad.

With that unnecessary power consumption, I feel bad for your neighbors too.
