It was our first winter closing/covering our pool. Unfortunately we don't have deck locks so it was weighted down with water bags, which worked well when they weren't leaking
Anyway - several of those bags failed and we ended up using a few old cement edging/landscaping blocks (about 30" long each, and pretty heavy) to weigh it down.
All winter I faithfully pumped the water off. And I had a few nightmares about waking up with the whole cover down in the pool - but it never happened. Until last night we have a bad thunderstorm about 2AM and apparently it rained A LOT. Woke up and the deep end blocks had been pulled into the pool. Best I can tell, one waterbag and two cement blocks are now at the bottom. Thankfully the large air pillows we use blocked the rest of the cover from going in, so it's really only the far end of the deep end that's in the pool.
I'm going to go ahead and take the cover off - a month earlier than I wanted to, but it got up to 82 yesterday so we're definitely done with frost warnings as far as I can tell!
I think I'm just going to have to wait another 2 months until I can dive down there and get the cement blocks out, yes? I can't think of any way to get them out (it's 8.5 feet down) - I don't suppose a pool company would have any equipment that could get something that heavy off the bottom - without tearing my new liner?
Thanks in advance for any advice...
