Hi Waste I have a few questions.
1. If you dont lower below returns and plug after it bubbles,how do you get antifreze in. Last pool guy just poured antifreeze straight in. Also I was wondering if I added at the chlorine feeder (never use) would it get there.The line that comes from it angles up to the jandy valve so I dont know if it would get there.
2. I have a d.e. filter. When I blow out the lines do I take the Drain plug out too. Also do you recommend taking it apart every year and clean the grid. The Pool builder did the first year. The pool guy that I used last year said not to.
3. Saw a pool store advertising a chemical to add when you backwash that prevents pump from rusting over winter. What do you think.

Thanks
