I see no reason why you would insulate them. When you close your pool for winter you will purge (empty) your pump and pipes. The water in the pool would freeze long before the water will in the pipes under ground.
28 degrees above zero (Fahrenheit) for more than 4 hours will freeze your pipes, so insulate, insulate, insulate.
to insulate and/or reinforce
To best insulate underground outdoor water pipes, use foam pipe insulation or fiberglass sleeves specifically designed for cold weather. Wrap the insulation around the pipes securely, ensuring there are no gaps, and use tape to hold it in place. Additionally, consider burying the pipes below the frost line, and if possible, add a layer of sand or soil on top for extra insulation. Lastly, using heat tape or cables can provide additional protection in extremely cold climates.
To prevent frozen pipes from bursting, you should thaw them slowly using a hairdryer or heating pad. Do not use open flames. Insulate pipes and keep faucets dripping to prevent freezing.
To prevent pipes from bursting during freezing temperatures, you should insulate exposed pipes, keep a consistent temperature in your home, allow faucets to drip, and open cabinet doors to allow warm air to circulate around pipes.
If the basement has ventilation to outside, the answer is yes. Heat loss from the pipes will escape outside the house. If the basement is closed to the outside then no, the pipes need not be insulated. Any heat lost from the pipes will provide some heating to the basement that will rise into the house.

Pipes can freeze at temperatures below 32 degrees Fahrenheit. To prevent this, you can insulate pipes, keep cabinets open to allow warm air circulation, and let faucets drip during cold weather.

well depending on the type of building and also depending on how old the building possibly is could depend on weather or not you would need to insulate the pipes.
No this is not necessary. Install the pipes as per usual. You can insulate the hot water pipes up to two meters or up to two yards from the hot water outlet from the hot water tank to prevent this.

Underground pipes can freeze when the temperature drops below 32 degrees Fahrenheit (0 degrees Celsius).
