I have read the sticky and still have questions. In particular, the pool discussed in the sticky does not have a main drain so that is not discussed at all. I have a main drain. Also, my plan was to lower my water level to below the returns, but the sticky info is for those who do not lower their water level.

My plan was to lower my water level to below the returns, disconnect and store the pump, disconnect and drain the filter and put anti-freeze in the lines.

- how do I keep the main drain line from freezing without completely emptying the pool?
- Anything else I need to do?
