When should I change the media in my swimming pool filter?
Sand media in a swimming pool filter can last up to five years and glass media can last up to 10 years.
Why is sand coming back into my pool?
The main cause of sand being filtered back into the swimming pool is due to broken laterals. If this is the case, then the sand/pea gravel will need to be emptied out of the filter and the laterals in the bottom will need to be replaced and then sand/pea gravel put back into the filter again taking care not to brake the new laterals.
Why is dirt coming back into my pool?
When dirt comes back into the swimming pool through the filtration system it is normally due to the filter needing to be backwashed and then rinsed or because the media might need to be replaced.
