Thread: Trting to deep clean the sand filter

    Trting to deep clean the sand filter

    Took off the lid to the sand filter, placed the hose into the sand bed, turned water on filled to the top. I went inside and when I came back out water was not running over the top. Is there a reason as to why? Where should I have my multiport turned to closed position?

    That would be my guess. All you're doing right now is filling the pool via the filter.

    If the multi-port is closed and working correctly, there is no other place for the water to go except out the top.

    Since it is apparently not, your multi-port must be letting water pass through back to the pool.....there is really no other path.

    You will need to disassemble the multiport and probably find the spider gasket damaged or misaligned.
