Thread: No breaks, no spaces in laterals...

    No breaks, no spaces in laterals...

    My Hayward SwimPro SW166T/164T is blowing sand and debris into the pool during filtration. It has always done it during backwash if I don't shut the valve on the return hose.
    The laterals and hub were new last summer. Only had the prob during backwash. Now it's always.
    I emptied sand and thoroughly inspected the umbrella laterals, hub, and center pipe. No cracks, no gaps, it still looks brand new. It is seated up top so well, I can't pull it apart.
    The only prob I saw was the gray "basket" looking thing that is on the base of the control valve (it's black on new ones) had fallen down and was lying in the sand/water in tank. A repair guy at our pool store said that would have nothing to do with it. I epoxied it back up where it belongs.
    So, is there something up in the valve that is bad? I'm stumped.

    That gray basket thing is called the overdrain diffuser.

    I'm not sure, it's whatever came with that filter.
    After the epoxy dried on diffuser for 24 hours I put laterals back in and replaced sand and it's not blowing back. So I guess I'll call it good.
