    Waste returns to pool when filtering to waste

    When set on "waste", some water returns to the pool. I am trying to vacuum after treating with flocculant and this is defeating the purpose of filtering to waste. What is wrong?

    Welcome to tfp, Brendazane

    It sounds like your spider gasket may need replacing. Have you taken your valve off and looked at it?

The SLAM process is not finished until: 1. CC < 0.5 ppm, 2. An OCLT < 1.0 ppm and, 3. The water is crystal clear.
