Is It Bad For Above Ground Pool To Overflow?

Finally! It’s swimming pool season! But before you get in the water, there are some things to keep in mind—including what happens if your above ground swimming pool overflows.

The answer is one of those annoying life hacks: it depends. If you have a saltwater swimming pool system, then yes, having too much water in your swimming pool could damage your system because of osmosis. And spilling swimming pool chemicals into waterways is never good for environmental reasons (or yourself), so let’s just say that overflowing an above-ground swimming pool is bad.

But if you have a regular swimming pool, overflowing it probably isn’t going to hurt anything—if anything it’ll help your swimming pool chemicals get where they need to go (e.g., everywhere).

It’s not like the swimming pool will break; unless you left a ton of toys in there, most above ground swimming pools can handle a good amount of water without issue.

And because the water is just going back into whatever body of water that swimming pool is in front of, whatever damage you could potentially do by spilling chemicals has already been done when you filled up the swimming pool.

Here is more on dealing with an overflowing swimming pool that’s above ground.

How Do I Stop My Above Ground Pool From Overflowing?

If you have a swimming pool system, there are two things you can do to prevent your swimming pool from overflowing.

First, clean up the water as it comes out so none of it is wasted.

Second, don’t fill the swimming pool quite so high. Then again, swimming pools usually overflow when their water level reaches 1 foot above ground or higher—and that shouldn’t be a problem for most saltwater swimming pools.

If you have a swimming pool pump and filter system, then this won’t be an issue because the pump will pump any surface water back into the swimming pool rather than let it run off anywhere else.

The same applies if you spilled some chemicals near your above ground swimming pool—as long as you cleaned them up immediately, they should be fine.

So really, you don’t have to do anything other than what you normally would whenever there’s an overflow.

Just clean up the swimming pool however you would when it overflows—whether that means using a skimmer or just scooping up all the water with buckets and dumping it back in the swimming pool—and check your swimming pool chemicals before you take a dip.

If everything looks good, then go for it! Just try not to have too much fun while swimming so none of that precious water gets wasted.

Water is precious, so where you live or how big your swimming pool is will determine if overflowing is bad.

And if cleanliness isn’t an issue then there’s no harm in overflowing your above ground swimming pool.

What Happens If You Overfill An Above Ground Pool?

The swimming pool water will likely overflow, either down the steps or onto a hard surface. If you’re lucky, the water level will fall by itself within a day or so.

Otherwise, you’ll need to take measures to remove some of the water.

This is particularly important if you have an inground swimming pool that’s above ground because sometimes they can be pretty heavy and it may damage something trying to lift it back into place.

Other than removing excess water, there isn’t much risk involved with filling your swimming pool too high – unless it causes excess pressure on your swimming pool walls. This might create tears or other damage that would require repairs.

If you don’t mind wasting all that swimming pool water then emptying your swimming pool isn’t really a big deal.

It’s not like your swimming pool is going to break and you’ll have swimming pool water everywhere. As long as the swimming pool isn’t full of toys, then it can handle that much water without any issue at all. In fact, most saltwater swimming pools come with a warning to add more chlorine when they’re full because it helps maintain enough chlorine levels in your swimming pool.

There are special considerations for overfilling an inground swimming pool, but nothing out of the ordinary if it’s an above ground swimming pool. You may even be able to turn the excess water into a source of hydroelectricity.

Final Thoughts


The swimming pool water level might rise, but that’s nothing to worry about unless it causes pressure on the swimming pool walls.

You can easily clean up any water that overflows and you might even be able to use it as a source of hydroelectricity.

When it comes to keeping your swimming pool safe and clean, there are three things you need to watch out for: swimming pool chemicals, leaks, and overflows.

If you find any of these issues in your swimming pool, don’t ignore them because they can cause rust underneath your swimming pool liner which will result in serious damage.
