I just purchased a home with a pool. While I have the chemistry down (thanks to this site) I'm finding I still have a few questions on the pump and filter I was hoping to get help on. Specifically:

The arrow points to a diverter valve which pumps the water to either filter A or B. Both use the same skimmer (there's only one), but return the water to the pool through a different return line. Why are there two filters and what is the purpose of the diverter valve?

This is right next to the pump and filter. The arrow points to a dial that I'm not sure the purpose of, but since the PVC pipe after it goes into the ground next to the pump I am assuming it's pool related. Any idea here?

Any thoughts would be appreciated. Otherwise, I'm enjoying my pool so far!
 
Welcome to the forum. :wave:

That Jandy energy filter is supposed to be some kind of pre-filter who's purpose remains kinda' unclear to me. I would take out the cartridge and not use it.

That's quite an installation you have. Does the mystery pipe go under the house? can you follow it?
 
Thanks!

I haven't been able to follow it yet since the crawlspace is covered with boxes, but plan on it shortly. It occurs to me it may be a shut off for the sprinklers as well.

As for the Jandy filter, is there typically any reason to have two filters in a pool?
 
I'd call Jandy, too, and/or search online in regards to that second filter. Never seen one like that before.

Pic 3 looks like a pool filler. That largish brass 'valve' thingy is a backflow device to prevent pool water from entering into your house water.

BTW, Welcome to TFP!! I see we are neighbors, too. :D
 
I searched around and saw another post which mentioned the Jandy filter being used for a pressure cleaner line. Perhaps that's a possibility, but I'll take the advice and call Jandy to see.

Thanks for the welcome, and I got a kick out of that main drain post. It makes me wonder what's in store for my pool :)
