    Sand in pool at start up

    Hello all,

    I replaced my filter with a Hayward S244T top mount sand filter, the bearings went out on the Hayward Super Pump for the third time so I replaced the pump with a Pentair 1hp "direct replacement pump" The Pentair seems to be a much better pump and the motor is beefier than the Smith motor on the hayward pump.

    I purchased the sand from a locally owned pool store and specifically asked for the No. 20 sand.
    Everything went well for a few weeks but now when the pump is turned on I get about a pound of sand (its being caught in a mesh bag so I know its sand) through the return.
    I have the top off the filter and am draining it for a look-see, any advice on what to do next?

    I found the issue, a lateral came loose, now to empty the sand and put it back together.

    After removing the sand and the laterals I found that when the assembly was put together at the factory they stripped out one of the screws. I shot a photo of the stripped out screw and will see if Hayward will warranty it.
