    Draining a Gunite Pool

    I want to drain about 10,000 gallons out of my 25,000 Gunite/plaster pool to bring down the CYA levels.
    What is the risk of popping the pool with that amount of drain?

    Are you in an area with a high water table? Is your yard soggy for a while after it rains? At the bottom of a hill? Will draining 10k gallons empty out one side of the pool?

    Is that Lebanon PA? Please add that to your profile.

    Very little unless your ground water is exceedingly high. Even then you're talking about less than 50%. It should be fine.
