A board that sticks out over a swimming pool, from which people can dive (= jump) into water below. Using a diving board can enhance safety in another way. Jumping off one helps divers clear the edge and walls of the pool. That helps ensure space to dive and helps divers hit the water at its deepest point—where it's the safest to submerge at high velocity.

Starting block in Swimming (sport), a raised platform mounted at the end of a pool from which swimmers begin a race. Starting blocks are raised platforms typically mounted on the pool deck at the end of competitive swimming lanes. In most installations, the height of the starting block platform above the water surface is less than 29 ½” above the water surface.

A filter is an item that is plumbed into the pool's plumbing network. As the water is pushed through, it will pass through the filter the dirt and debris are trapped inside. This creates clean and filtered water. The clean water flows through an outlet pipe back into the pool. Properly filtering and sanitizing your pool's water will keep it healthy and free of debris, bacteria and algae. Sand pool filters extract impurities from the pool water using sand to collect and attract the debris as small as 20 to 40 microns.

The purpose of swimming pool filtration is to clarify the water, which contains suspended particles, by passing it through a porous material. It also prevents the proliferation of algae. It consists of closed-circuit circulation by a pump and a certain quantity of filtration equipment (see below).

A pool filter is a component of a pool's filtration system that removes dirt and debris from water. A pump pulls water to the filter, the filter removes dirt and debris, and then clean water is returned to the pool through return jets on the pool walls. Without a filter pump, the bacteria and dirt will remain in the swimming pool. This will then quickly make your pool a breeding ground for diseases instead of a healthy wellness environment. That's something you definitely have to avoid!

The purpose of swimming pool filtration is to clarify the water, which contains suspended particles, by passing it through a porous material. It also prevents the proliferation of algae. It consists of closed-circuit circulation by a pump and a certain quantity of filtration equipment (see below). These are the two capacity filters which do not need any alteration in already built swimming pool or new swimming pools. These filters are visible at the pool deck and easy to install and easy to use. These are the safest swimming pool water filters.
