If you have an in ground pool, in freezing weather, make sure you leave your on pump constantly to circulate the water, if not you could have damage to your pump, and breaking water pipes. The water might freeze on top of the pool, but underneath the water should still be circulating, if not find something to break the ice on top. Freezing pool water is normal. Unfortunately, dented sides and losing sand are not. You probably have a leak that is squirting the sand out, and sucking in the sides. or the cove failed. Either way, if it was professionally installed, they screwed up. I heard that if you filled about 5-6 liter bottles half way with sand and placed in your pool, the pool water would not freeze due to the bottles floating around and constantly breaking up the water so as not to freeze.
No, water should not be kept in your pool all winter. When it gets cold enough, the water will freeze. When water freezes, it expands. So when the water in your pool freezes and expands your pool will be ruined.
Water expands as it freezes. Many people put inflatable devices in the pool before covering for the winter to give expanding ice somewhere to go instead of pushing outward on the pool.
If it freezes it can end up bursting and cause water to go into the ally way.
Saltwater freezes too, just at a couple degrees lower than fresh water.
Not all above ground pools have to be disassembled during winter, although it is a good idea to drain them. Water expands when it freezes, and if the water is trapped in a closed container or in a crack, the expansion can break the container or the material surrounding it. Pipes often break, when water inside them freezes.
When it freezes.
cold water freezes fasterHot freezes faster than cold.Cold water freezes faster.
Normally the filtration equipment of a pool is drained to reduce the risk of water freezing in the equipment and wrecking it However of the water is not getting so cold that it freezes in the pipes you would be better of ruining it on filter You may as well keep the water as clean as possible
You should fill in the pool. A dead frog will ruin your pool forever.
It floats when it freezes.
if you have closed your pool down for the winter (i.e. winterized it) then no. you should have put in a good dose of chemicals & if you live in an area the freezes you should drain the pool an inch or two below the water jets so you won't be able to run the pump anyway
