I had a post a couple years back, and people liked the pictorial. I have updated my website and the previous link was no longer functioning.
So I am posting my BIAB pictorial, and the updated link.
It is a Kolsch from scratch. Enjoy:

I also edited the older post to have the new link.
Sorry if anyone could not find it...

Yes,
The pool filter has a diversion valve to use to empty the pool a bit after it rains, or to lower the water level for servicing. That has a standard hose valve and bib on it.
So while pool filter is running, you can use that hose bib just like a garden hose, only drawing water from the pool.
Then the water routed through the copper cooling coil is rerouted back into the pool instead of down the drain or into the street.
