    Lost DE through Multiport Valve

    I took the filter apart, cleaned the grids and recharged the filter (5 lbs of DE). After about 30 minutes, noticed that the pool level was down. Discovered that the spider gasket on multiport valve was mangled. After changing the spider gasket do I need to replenish all the DE? One away to know for sure is to dismantle the filter. Any other ideas? Thanks.

    If you don't see any DE in the pool, the internal leak probably was before the filter and you should be okay. If there's DE drifts ion the pool, vacuum them up and backwash and recharge with 80%

    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!
