Calcium lumps in a pool are calcium deposits that form when a pool's water parameters are not in the normal range. They can float around on the surface of the pool water, making it look and feel dirty. The most common causes of calcium lumps in pools are calcium hardness above 1,000 ppm, alkalinity over 120, and a pH over 7.8. Keeping your pool’s calcium levels, alkalinity, and pH levels within the normal, safe ranges is the best way to prevent calcium lumps and other problems, including damage to the pool surface.

You can spend less time and money on plunge pool maintenance since they are smaller than standard pools. These pools are easier to clean and maintain yourself than a swimming pool. But like any pool, you’ll need to clean the pool walls and floor, balance the chemicals, check the electrical equipment, make necessary repairs, etc.

Whether your homeowners insurance covers a pool leak depends on your specific policy, so it's essential to check your policy documents before taking on any repairs. Typically, leaks caused by a covered event, such as a fallen tree branch or a fire, may be covered. However, leaks resulting from general wear and tear or poor maintenance are usually not. It is also a good practice to review your homeowners insurance policy before installing a pool to fully understand your personal liability and coverage.

Vinyl pools are the least expensive for installation thanks to the relatively low cost of vinyl pool liners. However, vinyl liners do not last as long as fiberglass or concrete designs, which could balance out the cost of the pool overall depending on its size.
