How Often Should an Arizona Pool Be Drained?

Why Arizona Pools Need a Fresh Start Every Few Years
If you own a pool in Arizona, keeping the water clear and balanced is only part of taking care of it. Over time, our extremely hard Arizona water leaves behind minerals and dissolved solids that regular chemicals and filtration simply can’t remove.

That’s why periodically draining your pool and giving it a thorough cleaning can be an important part of long-term pool care.

Arizona Water Is HARD on Pools
Every time water evaporates from your pool—which happens constantly in the Arizona heat—the water disappears, but the minerals stay behind.

Then you add more water.

More evaporation. More minerals. More water.

Over the years, those minerals and dissolved solids can continue to build up in your pool water and on pool surfaces. This can contribute to:

Calcium and scale buildup
White deposits along tile and waterlines
Water that becomes increasingly difficult to balance
Reduced effectiveness of pool chemicals
Staining or discoloration
Rough pool surfaces
Extra stress on equipment
A pool that just doesn’t look or feel as fresh as it should
Sometimes Your Pool Water Needs a Reset
Adding more chemicals isn’t always the answer.

Depending on your water chemistry and the condition of the pool, replacing old water with fresh water can give your pool a much-needed reset. A professional drain also creates an opportunity to thoroughly inspect and clean areas that normally stay underwater.

This may include cleaning the pool interior, addressing scale and buildup, inspecting tile and grout, checking fittings and drains, and looking for signs of surface deterioration or other issues before they become bigger repairs.

How Often Should an Arizona Pool Be Drained?
There isn’t one magic number for every pool.

Many Arizona pools may benefit from water replacement every few years, but the right timing depends on your individual pool, source water, chemical history, calcium hardness, total dissolved solids, stabilizer levels and overall condition.

Test the water—not just the calendar.

At Desert Island Pools, we believe pool owners should understand why something needs to be done before spending money on it.

Don’t Drain an Arizona Pool Without a Plan
This part is important: draining a swimming pool should be done carefully and at the appropriate time of year.

Arizona’s extreme temperatures can make an empty pool vulnerable to surface damage, and other conditions can also make draining unsafe for the pool itself. A pool should never be left empty longer than necessary, especially during hot weather.

Before draining, the pool and current conditions should be evaluated so the process can be completed safely and efficiently.

Give Your Backyard Investment a Little Love
Your pool is one of the hardest-working features in an Arizona backyard. Fresh water, proper chemistry and periodic deep cleaning can help protect the pool’s finish, equipment and appearance—and keep the water more enjoyable for your family.

Not sure when your pool was last drained or whether it’s time?
