how do i backwash

[SBaker]

I have the same Intex pool and there is no backwashing required. Just clean the filter as Dennis mentioned and also clean the debris screen. You can go to the Intex website and download or just view the instructions for the pool and the filter. Your pool should have a valve on the supply and return lines that you close to prevent water from flowing when you are cleaning the filter and debris screen. Make sure you open the lower valve first (the supply line) and then the other valve to minimize the amount of air trapped in the hoses. Then open the screw on top of the filter cover to bleed the remaining air from the pump/filter prior to turning the pump on.
