Next year will be our fourth season for our pool and I was wondering what is the life span of the sand in the filter? I am thinking it is probably at its maximum after 3 seasons. We have been closing it and not running it for the winter months here in GA so it hasnt been running for a complete 12 months the past three years perhaps 20 months of the 36 months we have had the pool.
When I replace the sand how much do I get and is there some maintenance I should do on the head or laterals while its appart and the head is off?
Thanks for the advice in advance !
