    Do I need to "isolate" my sand filter from the system to deep clean?

    I want to deep clean (or at least rinse the sand in) my Hayward S200 sand filter. Do I need to isolate it from my system if I have an inground pool and the filter is above ground? If so, how do I do this? (I will need very simplified instructions. The multiport on my S200 is on the side.)

    I think if you just set the multiport to waste or off it will close the ports to the sand filter. Then nothing can get sent out the wrong pipe.

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.
    A pool is like a pet - you have to feed it every day, even the days you don't want to play with it!
