If you could do it over again or people that have switched, which one do you prefer?
Currently use sand here, thinking of switching to cartridge, this year hardly getting any rain and with the increase in swimmer load i,m back washing more often.
If you have switched from sand to cartridge, did you incease water flow? And how much pressure drop did you get by switching?
My starting psi is 19 and i backwash at about 23-24
