***I changed the title of the post since it appears that the Main Drain may be part of the problem I'm having***
Our pool was built in 1994. It is a free form pool. (See pic below). There are currently three returns in the shallow end, and one in the middle "section" but currently there are no returns in the deep end of the pool (just has the main drain).
1. Is it "normal" not to have a return in a section of the pool like that? The deep end gets NO circulation to speak of. We have a product called The Circulator in two of the returns, one in the shallow end and one in that single return in the middle section (if you look closely in the middle section, you can see a small white dot. That is the only return in the half of the pool) which does a great job of circulate the surrounding water, but that deep end really appears to get no circulation.
2. Does it make sense to have a return put in the deep end? I know it would entail cutting up the current deck, which doesn't bother me because I want to resurface that deck anyway.
Maybe we just need to keep brushing that deep end every day. That certainly would be cheaper, but is having a return to move that water around on a continual basis better?
I'm just tossing ideas around in my head (and here). My knowledge of all this is 'nil so if it is a stupid idea, be gentle to me in your responses!
