To prevent this from happening keep a cover pump on the winter cover and pump water off of it when you see it accumulating.
No ice,, and a pump stays on the cover as long as the temperature is above freezing. It was from the 6 to 7 inchs of rain we got a couple of weeks ago in a short span. I had the pool company come out and put the liner back in and put in the liner lock and also plumb in the french drain ( which they should have done in the first place). Then 4 days after they finished we got another 5 to 6 inchs of rain in 24 hours with 4 of it in one night. It floated the liner up with big bubbles but it stayed locked in the track. I have pumped what looks like at least hundreds if not thousands of gallons of water from under the liner. It is so filthy I can't see the bottom to know if I have it all out but am now running the filter non-stop. Any ideas on how to speed up the cleaning without pumping out the water. I am on well water and that is my last option. Thanks for all the advice.
