Is It Bad If an Inground Pool Overflows?

If you get more than five inches of rain in an hour, or if your pool wasn't properly designed with sufficient overflows, then your pool may overflow, which can put you at risk of water getting inside of your home and causing serious damage. As your pool fills with water, it may overflow into your yard.

What happens if my inground pool overflows?

When your pool overflows, your pool becomes diluted and throws the chemical balance off. Not only that, but rainwater also tends to carry pollutants with it that can cause contamination that needs to be dealt with.

Is it bad for a pool to be too full?

The quick answer is no. You don't need to drain your pool, as there is no risk to your pool by it being full. The only thing you lose with a pool filled to the rim is your skimmer's surface cleaning action. Overall, it still draws water and the equipment is just fine.
