How Often Do I Need to Change My Swimming Pool Water?

The frequency of how often you change your swimming pool water depends on how much you use it and how often the filter runs. If they are not used very frequently, some pools only need to be changed every few years. If you want to be safe and make sure that it is completely clean, you should most likely try to drain the pool and put the water in it every year. Some public pools will drain the water and replace the it twice a year since they get a lot more use than a private pool would.
