How Often Should a Pool Be Drained—And Why It Matters

August 26, 20250

Draining a pool isn’t the most exciting subject. It doesn’t have the flash of new tile or the fun of picking out LED lights that change colors for backyard parties. But ask anyone who’s dealt with cloudy water, scaling on the plaster, or equipment that’s working twice as hard as it should, and the importance of draining suddenly becomes crystal clear.

Why Pools Need Draining

A pool is basically a closed system. The water doesn’t cycle out naturally, and over time it becomes overloaded with dissolved solids, minerals, and chemicals. Even with the best maintenance routines, that build-up keeps happening in the background.

Think of it like sweet tea left out on the counter too long. At first, it’s fine. After a while, though, it just doesn’t taste right. Pools work the same way. Water that’s been hanging around for too long stops responding the way it should to treatments. Chlorine doesn’t sanitize as well, stains start to show, and scale creeps in on plaster and tile.

That’s when a drain-and-refill resets everything, giving the pool a fresh start.

How Often Is Enough?

The big question is how often to do it. There’s no one-size-fits-all answer. In southern Louisiana, the climate plays a huge role. Long, hot summers, heavy rain, and nearly year-round use put extra stress on pool water.

On average, most pools benefit from a full or partial drain every three to five years. But certain conditions can shorten that timeline:

  • High usage: Pools with lots of swimmers, sunscreen, and activity collect contaminants faster.
  • Water chemistry: When stabilizer levels or total dissolved solids climb beyond recommended ranges, treatments stop working effectively.
  • Surface type: Plaster, vinyl, and fiberglass all react differently to imbalanced water, sometimes forcing earlier intervention.

The key is paying attention to the water’s behavior. If chemical adjustments stop having much effect, draining is usually the next step.

What Happens If It’s Ignored

Skipping this step might seem like an easy shortcut, but the problems catch up eventually. Excess calcium leads to rough surfaces and unsightly scaling. Pumps and heaters start straining against mineral-heavy water, cutting years off their service life. And water overloaded with dissolved solids becomes more likely to host algae, even when sanitizer levels look good on paper.

In the worst cases, the structure itself can be affected. Plaster finishes wear out faster, and liners may weaken under constant chemical stress. What could have been a simple water change turns into costly repairs.

Drainage Done Safely

Pulling the plug and letting the water run out isn’t the right way to go about it. Pools are heavy structures set into shifting Louisiana soil. Draining too quickly or under the wrong conditions can put pressure on the shell from surrounding groundwater, leading to cracks or even structural movement.

A careful approach is always best. Water needs to be lowered at the proper rate, and disposal has to follow guidelines that keep chemicals out of storm drains and landscaping. Done correctly, draining protects both the pool and the environment.

Special Considerations in Louisiana

Metairie and the surrounding region bring their own set of challenges. Warm, humid conditions accelerate chemical changes in water. Storms and heavy rainfall introduce new contaminants, while frequent evaporation during hot stretches leaves behind concentrated minerals.

All of these factors combine to make regular draining even more important locally than in cooler or drier climates. Without it, pools in this region face higher risks of scaling, cloudy water, and equipment wear.

Long-Term Benefits

Draining a pool might feel like a chore, but it’s one of the best long-term investments in maintenance. Fresh water means balanced chemistry, which keeps surfaces smooth, equipment running efficiently, and swimmers safe.

It also gives an opportunity to inspect surfaces and make minor repairs before they become major headaches. A clean, fresh start every few years saves time and money over the lifespan of the pool.

The Practical Approach

Instead of treating draining as an afterthought, think of it as part of the bigger picture of pool ownership. Skimming, vacuuming, brushing, and chemical checks handle the short-term needs. Draining every few years resets the clock. Both are necessary to keep things running smoothly.

It’s not glamorous, but it works. Pools are a big investment, and protecting that investment means keeping the water in balance. A fresh fill is often the simplest way to make sure the chemistry plays nice with plaster, tile, pumps, and filters.

Closing Thoughts

Owning a pool in southern Louisiana is a joy, but it comes with responsibilities. Water doesn’t stay the same forever, and even the best upkeep eventually hits a wall. That’s when draining steps in—not as an emergency measure, but as regular maintenance.

Every few years, it’s worth giving a pool that reset. The payoff comes in clearer water, healthier swimmers, longer-lasting equipment, and fewer repair bills down the line. And while draining might not get the same attention as planning the next crawfish boil by the poolside, it’s the quiet detail that keeps the fun going without interruption.
