Hi all, new pool owner here. I can't seem to figure out what all of my valves on controlling. Hopefully the pics are posted below. Sorry I can't provide better pics, the lattice around everything makes for tight quarters.
Anyway, here's what (I think) I know... (top to bottom). Pressure side: goes through chlorinator and into three-way valve which is currently flowing to the returns only. The other direction provides flow to the waterfall. In the second pic, you can see 2 smaller pipes that go into the ground between the 3-way valve and the return... hard to see, but those pipes each have an on-off valve and they each control a spray (I think that's the correct term) at either end of the pool. I'm pretty sure I have this side correct, yes?
So, moving on to the suction side... 2 pipes that come out of the ground, I can figure that out, skimmer and drain, right? But what the heck is the deal with the pipe connecting the return side to the suction side. My guess is that the top suction pipe is the drain. I guess that's the reason for the 3-ways connecting it to the return... so I can send return water out of the drain, maybe??? Why would I need to do that?
So then the suction line with the blue on-off valve I can deduce must be the skimmer.
The rest I am ok on, next one down (single smaller pipe that heads off to the right) is the suction for the booster pump, and the other small pipe on bottom that comes out of the ground and goes back in with the electronic valve is for the Levolor.
So did I get this all right? Also, there are 2 drains in my pool. My assumption is that one is the main drain and the other is connected to the suction side of the booster pump. Correct, or am I off base?
Sorry, I know this is way long, and if you're still reading at this point, I greatly appreciate it. Here are the pics (I hope).
