    Newbie - Best / safest way to drain inground pool

    HI - New guy here, with a 25k gallon pool in need of draining. (High CH and CYa). My estimate is that I need to drop it by 1/2.

    I'm told it's dangerous to drain, and I understand why. But I don't need to go all the way down. The bottom will always be covered by at least 6" of water. Of course, I live in an area which is basically sand (near the ocean).

    Do I need to hire professional? Can I do it myself? What is a pro doing that I couldn't do? I'm assuming they are not putting up scaffolding to support the walls, right?

    Oh - I should add it's a vinyl liner.

    Welcome to the forum.
    The safest and best (IMO) way is to do a series of partial drains.

    Drain 1/4 - 1/3 and then refill
    Drain 1/4 - 1/3 and then refill
    Drain 1/4 - 1/3 and then refill

    until you get to the desired level. That way you will require no support by draining partially and, while you will use a bit more water, it turns out to be really not that much more.

    I agree with Dave but I'd ask another question. Where are you located? Depending on the location you may have another option. If you live on the west coast or in Az R/O might be available in your area.
