Run your pool pump continuously when temperatures are near or below freezing. You don't need to run your heater, moving water likely will not freeze. Disconnect any aerators and lines to slides. Booster pumps for pool cleaners don't need to run continuously.
If you have an above ground pool with the pool filter system and plumbing above ground (like nearly all above ground pools), pipes and pumps can freeze up in less than an hour of minus 32 degrees. The same is true for inground pool equipment that is not running when temperatures are below freezing.
It's important to remember that you don't need to run your heater to prevent your pool water from freezing. In fact, running your heater in freezing conditions can cause substantial damage to the unit. If your pool has ice on its surface, break it up so that the skimmers and skimmer doors are kept clear.
KEEP YOUR POOL MAINTENANCE UP TO DATE
If you do not keep up with these maintenance items, then the flow of water through your pool equipment will be greatly diminished. In a freeze situation, this can lead to freeze damage on your equipment.
Bring the pump housing into an area where the temperature is above freezing. Eventually, the ice in the pump melts and the pump can be flushed, winterized and reconnected back into the filtration lines of the pool.
Pipes can freeze at 32 degrees or below, but it will take a sustained period of time for this to happen. In other words, a pipe needs to be at freezing temperatures for at least half a day before homeowners have to worry about any freezing occurring.
No! All pool types (in-ground, above ground, on-ground) need to keep water in the pool during winter, do not drain your pool to avoid the ice! In ground pools can pop out of the ground, and above ground pools can collapse inward, and the liner will shrink and discolor.
Pool pipes that are located above-ground can crack if the pump is not kept running when temperatures reach below 32°. If PVC pipes freeze, the ice will expand and can crack pipes, pumps, valves, filters, and heaters.
While a thin layer of ice is unlikely to damage your pool, if you live in an area with continuous below-freezing temperatures, we highly recommend you winterize and close your pool at the end of swimming season. Keeping your pool open all year long is also an option.
As a general rule of thumb, in order for your home's water pipes to freeze, the outside temperature needs to be below 20 degrees, for a total of at least six consecutive hours.
When temperatures dip to 28 degrees or below, and the outside faucets freeze, ice can form in the water supply pipes that lead to those exposed outdoor faucets. If your outdoor faucets aren't properly prepared for winter, water damage from frozen pipes may occur.
When the weather is very cold outside, let the cold water drip from the faucet served by exposed pipes. Running water through the pipe - even at a trickle - helps prevent pipes from freezing.
Approximately two weeks must pass for water inside your filter, pump and pipes to freeze completely, so your pool's lines may not be frozen just because there is a layer of ice on top of the water surface.
Information varies on how cold it has to be for pipes to freeze, but the freezing temperature of water is 32 degrees. So, theoretically, your pipes could freeze at any temperature lower than that. But for your pipes to literally freeze overnight, the temperature would probably have to drop to at least 20 degrees.
To prevent pipes from freezing, the best thing to do is turn your water off if you can locate your valve. If not, leaving your faucets on with a slight trickle - not a drip - to prevent broken pipes, he says.
Plan to remove hoses and turn off the water to outside faucets 2 weeks before the first average fall freeze. In most regions with freezing winters, October or November is the best month to winterize your hoses and hose bibbs.
DURING freezing weather:
If you plan to be away from home for several days, shutting off the water can reduce the chances of broken pipes. Set your home heat to at least 55 degrees. Shut off water to the house and open all faucets to drain pipes; flush the toilet once to drain the tank, but not the bowl.
This can happen any time the air surrounding the pipes reaches below freezing, which is 32 degrees Fahrenheit. As the water heat transfers to the cold air, the water temperature drops to the point that it starts to freeze. Ice in the pipes causes a pressure backup, which can cause the pipe to burst.
See, in most cases, your water pipes will start freezing when the temperature is within the range of twenty to thirty two degrees Fahrenheit. And since they need around six hours until they burst, this temperature rate can be considered the one at which your water lines will collapse.
As a general rule, temperatures outside must drop to at least 20 degrees or lower to cause pipes to freeze. In northern climates, where the temperatures regularly fall below freezing, modern homes tend to be well insulated and water pipes are located on the inner parts of the house for extra protection.
Chlorinated and non-chlorinated pools freeze at the same temperature. However, salt water pools will freeze at a slightly lower temperature. It should also be noted that above-ground pools will generally freeze at a higher temperature than inground pools.
Keep your faucet open.
Water and steam will be created during the thawing process, and your pipes need an opening to discharge this. Keeping the faucet open also allows for moving water to run through the pipe, which will expedite the thawing process.
Pipes can freeze in as little as six to eight hours, meaning they can freeze overnight. If the outside temperature is below 32 degrees F and your pipes are unprotected, your chances for a frozen pipe increase.
