I wanted to post some pics and hopefully get some advice before this is final. I am installing four 4x20 Fafco panels in parallel on a flat roof while my pool is being remodeled. You can see the entire post here - inground-total-redo-going-for-broke-t41950.html
The pool has 1 skimmer, 1 drain, 2 return eyes. It looks like the return line continues around the pool making a full circle back through letter B in picture.
The pool builder made connections today and I will continue from there when I'm sure things are ok.
Here is what I think is going on:
A) Water from pump and filter traveling to the right
B) Return line circle from around pool making a loop
C) Return to pool
D) Cold line to solar (New today)
E) Hot line from solar (New today)
F) Never used or plumbed Polaris pipe
(F is not connected to C)
(the buried pipe to the left of the actual letter D is old drainage pipe)
At the siding covered wall where the pipes go up you can just barely see I've installed the cold side check valve. I will install a 3 way diverter valve above it. Then heated and non diverted water will come back down E.
My main question is does there need to be a total separation at the pipes and elbows of D and E where I have the yellow line? This would make all return water pass through D, then divert whatever % to solar and to return.
If there is no separation then it seems like return water from A and B will go to C and not make it to solar.
These guys are going to want to cover this up soon and work on other stuff so quick advice is very much appreciated.
