If the end of the hose is running in a pool of water, yes
Yes, the pool pump typically needs to be running when the pool heater is operating. This ensures proper water circulation, allowing the heater to efficiently warm the water and preventing overheating or damage to the heater. Additionally, running the pump helps distribute the heated water evenly throughout the pool. Always check the specific manufacturer's guidelines for your equipment for optimal operation.
No running. No diving in the shallows water.
That depends on the size of the pool and how fast the water is running that is filling it.

So long as there is water coming through the pump when it is running it doesnt matter what the water level in the pool is.
YES if you keep water running lol
Yes, it is advisable to keep your pool running in temperatures around 32 degrees Fahrenheit to prevent the water from freezing, which can damage pool equipment and plumbing. Circulating water helps maintain a consistent temperature and reduces the risk of ice formation. Additionally, running the pump can help maintain water quality by preventing stagnation.
