This is my third winter with 20 by 40 rectangular vinyl liner pool in CT. The deepest end is about 9 feet deep, the shallow end is 4 feet.
The first year was a disaster. I've bought the house close to the winter and before I know the ice was in pipes and a skimmer. Somehow the pool survived with no damage.
The second year I did some reasearch and drained it below skimmer and inlet and return lines. I dont have drain on a bottom , so it's one inlet port , one skimmer and two return line ports. All the ports are 4 inches below the skimmer . So, I've drained the pool at about 5 inches below inlet and return lines, added chemicals and put safety cover over it.
Everyrthing was just fine until we got several heavy snowfalls last year. The safety cover was caving really bad. Some anchors got pulled away and some spring clips got destroyed.
Not sure what to do this year.
- Should I drain it like last year and reinforce ancors and and springs ?
- Should I put some kind of inflatable bags to support safety cover?
- Should I keep the water in pool and just blow the lines and cover them?
I am lost a this point. Thank you for advice.
