Here is my dilemma,
First time pool owner here. I used the BBB method all summer and it worked amazing as expected So here we go: a little about my pool, I moved in in April and the pool was uncovered and drained below the first return (It has a dual return). The other return still had the hose connected with a plug installed. So after converting the pool to BBB the summer went fine no problems at all. I closed my pool in October, I drained it past the first return and left the hose connected with plug installed. Fast forward to today: I come home from work and notice that my pool is empty, I found that the plug that was in the second return came out and of course drained my pool. My question is, should I fill the pool back up or just wait until I open it in May? Right now my cover is installed and could fill with rain water. The weather has been below freezing for the last week. I was so looking forward to taking the cover off and posting some pictures of how well my opening went due to the BBB method used the season prior. Any information would be helpful in this matter, and thank you in advance.
