My pool need a major re-surfacing project; and since my current pump and filter have been used for a while; I am considering to replace the entire system.
Currently having a 1.5HP Hayward 110V single speed pump; and DE4820 Hayward filter.
I am considering to replace the single speed pump with 220V Varied Frequency Pump to save energy cost.
And I spotted Hayward selling the the Swimclear Cartridge type filter. Reason I am considering switching over to Cartridge type is the cleaning of DE filter will generate lots of dirty DE waste; which I have no idea where to clean the filter the best without dealing with these wastes.
My pool is a 22,000 Gallon in ground pool. Is there any good suggestion? And what are the pros & cons of using the cartridge type filter. Based on a brief research and calculationg, I found the varied Frequency pump to use in my case must generate minimum 60~70psi for cleaning the pool in 8hr period. But the Cartridge type filter can only take a maximum water pressure at 50psi. Would this be a problem to combine them in my search for solutions?
