    Help! Sand in pool!

    Hooked up brand new sand pump with brand new pool and noticed sand in the bottom after attempting to backwash. Realized hoses were connected incorrectly so we fixed it.
    Ran pump several days later and more sand is back. Help!!!! It's right under the port that send water back in.

    Re: Help! Sand in pool!

    Sand returning back to the pool is usually a sign of one or more of the following:
    - Incorrect sand used (must be #20 silica pool sand)
    - Too much sand was added
    - Damage to, or separation of, internal parts (laterals, center stand pipe, etc) (Did you fill the filter halfway with water "before" adding the sand?)
    - Multiport valve damaged or internal spider gasket not sealing properly

    If all of this is new equipment, you might hope that it's something simple like the sand, or inspecting the laterals inside to make sure nothing came apart. If you rule everything out and believe it may be a defective part of the filter, it should still be under warranty. If the sand returning in from the jet(s) is small, you might try hanging a sock with a small hole in it over the jet opening for a while. It may catch some of the smaller sand particles until the issue resolves itself if it's just the type of sand that was used and nothing else.

    It hasn't had any sand in the last week since the original two dumpings and I've been running it nightly. Not sure what to do---if I should just return and get new pump to be safe or cross fingers it worked itself out. I'm using correct sand.

    Keep an eye on it for now. Perhaps just a break-in period or the sand needed to settle. If it becomes an issue, you can always contact the manufacture. Some of them are quite good about helping customers.

    I am having the same issue with my Intex sand filter. I have tried the pea gravel and changed the sand two different times. I think I have found a fix though. I bought a Hayward S166T Pro Series sand filter. It will be here Wednesday. Hopefully no more sand in my pool!

    Ended up taking it back. Too expensive to take chances!!! Hooked up new one and so far so good but I guess we'll see. Fingers crossed!

    Make sure you are rinsing after backwashing. We had the same problem.
