The recommended depth of 4 feet of water for a residential pool safety cover is considered optimal for several reasons. First, having this depth of water helps to keep the cover taut and reduces the risk of sagging, which can lead to the accumulation of debris and water on top of the cover. A well-supported cover is also crucial for safety, as it can better withstand the weight of snow, ice, or individuals who may inadvertently walk on it.

Additionally, a deeper water level can help prevent the growth of algae and unwanted microorganisms that can thrive in stagnant water, thus contributing to a healthier pool environment. A 4-foot depth is generally sufficient to provide adequate safety and functionality without the risks associated with shallower or deeper depths.

It is important to note that depths less than 4 feet may not offer the same safety and effectiveness in managing seasonal debris, while depths greater than 4 feet may not be practical for maintenance and could pose challenges during winterization or pool cleaning.
