Water volleyball nets are made of the same nylon material as used in volleyball nets. The nylon material should be springy enough to provide proper resistance and appropriate wear-and-tear, but should not be bouncy. A stiffer, more wiry net can be used on a permanently mounted net system. The wiry netting material lasts longer but should be used with care as it requires a bit more maintenance and should not be left outdoors.
Water volleyball nets are typically anchored on two sides by either a weighted post or a permanently mounted post (similar to a volleyball net). Weighted posts for water volleyball nets are usually filled with sand or water and placed out of the pool at opposite edges. This type of post works well for casual players and small and large pools alike. The advantages of these types of nets is that they are relatively inexpensive and are simple to setup. The only drawbacks are that the post may need an occasional cleaning to remove the sand or water, the posts may need to be repositioned during the game (if the net is hit too hard or pulled on by players), and it may need a little more setup time in the beginning of the game. They also do not tend to last as long as permanently mounted nets.
Permanently mounted water volleyball nets are more appropriate for larger or industrial/commercial pools like at schools or recreation center pools. These nets are typically mounted to concrete-mounted steel poles or on grommets or hooks build into the ceiling of the walls outside the pool. The advantages of these types of nets are that they very sturdy and the nets feel solid. They also last a long time with considerate use and maintenance.
