In most cases, your pool can even handle rain from most tropical depressions and hurricanes. If your pool is completely full after a storm or heavy rainfall, you don't need to take drastic steps such as emptying your pool.

When your pool overflows, your pool becomes diluted and throws the chemical balance off. Not only that, but rainwater also tends to carry pollutants with it that can cause contamination that needs to be dealt with.
Rainfall dilutes pool chemistry levels and lowers the readings for pH, alkalinity, hardness, stabilizer, and chlorine. Rainfall does not contain chlorine. As well, rainfall brings with it small amounts of contaminants that are washed into the pool.
"Heavy rain dilutes pool chemicals, especially salt and chlorine, which causes the pool to turn green. This means the water is not sanitised or healthy, so it's vital to address this.

The Department of Environmental Health recommends avoiding activities such as swimming, surfing, and diving for 72 hours after it rains. Research has shown that the risk of infection is the highest during and the day after rain, and declines to around normal levels after three days.
If you can pump around 30 GPM (gallons per minute), which is also equivalent to 1800 GPH (gallons per hour), it should take you 2.78 hours or 2 hours and 46 minutes to drain your pool using a hose.
Put one end of your garden hose inside the port. Thread the hose to the back of your house. Attach the other end of the garden hose to a submersion pump and place the hose and pump in the deepest area of your pool, near the drain. The pool will begin to drain.
Every pool must turn over at least once a day, so most pool pumps should run approximately 8 hours a day. But here's the thing: you don't have to run your pool pump consecutively. You can choose to run it for three hours in the morning before you leave for work and another 5 hours in the evening.
The first choice for draining swimming pool water should be to drain pool water into the sanitary sewer. In-ground pools typically have a sanitary sewer drainage inlet near the pool equipment. Pools and spas not plumbed with a sanitary sewer drainage inlet can be drained to a sanitary sewer line plumbed to the home.
Answer: It should not matter much. It could help to filter debris and contaminants the rain washes into the pool. However, lightning can be a concern with the filter running.
How long can you leave a pool empty? Well, the minimum amount of time possible in order to minimize the risk of serious damage. Most issues that require a pool drain will take at least a day or two to resolve, but it's recommended to not let it sit empty for any extended period of time.
You can reasonably expect to need to drain your pool every few years.

This siphoning process is simple enough. Immerse the entire hose in some water, then cover one end of the hose with your hand and quickly pull it out of the pool, pointing down below the water level. If you don't cut the hose, you may need to attach the hose to your spigot and fill it with water.
