Should You Drain Your Pool Completely?

There’s something oddly satisfying about the idea of starting fresh—like draining your pool completely and refilling it with sparkling new water. But before you grab a sump pump and commit to a weekend project, hold that thought. Draining a pool sounds simple, but if you do it at the wrong time or for the wrong reasons, you could end up doing more harm than good.

Here in Northern California, with its mix of clay-heavy soil, water restrictions, and unpredictable weather, the decision to drain a pool isn’t one to take lightly. So how do you know when it actually makes sense to do a full drain? And when should you leave the water where it is?

When Draining Might Be Necessary

Draining your pool isn’t always a bad idea. In fact, there are times when it’s the best or only option.

If your pool has a major chemical imbalance that can’t be corrected with standard treatment, or if the total dissolved solids (TDS) are sky-high, starting over might be your best bet. Pools with old, stained, or damaged surfaces also benefit from a drain when it’s time for resurfacing. Algae blooms that have gotten out of control sometimes require a reset, too, especially if they’ve been left unchecked for a long time.

Risks of Draining a Pool in Northern California

Even if your pool water is looking rough, draining the entire pool comes with some serious risks—especially in areas like Lincoln, Rocklin, Roseville, and other parts of Northern California. Our soil here can retain moisture, which puts pressure on an empty pool shell. If you drain your pool at the wrong time (like during or right after heavy rains), the structure could actually float or crack.

There are also environmental regulations and water use restrictions to consider. Draining thousands of gallons of water all at once could violate local codes or trigger a hefty fine.

Better Alternatives to Draining

Instead of doing a full drain, partial draining might do the trick. Removing just a portion of the water and refilling with fresh water can help reduce TDS and balance your chemical levels. This approach also minimizes structural risks and doesn’t leave your pool completely vulnerable.

Another good option? Shock treatments and a deep cleaning from a professional. In many cases, aggressive algae and chemical issues can be resolved without pulling the plug on all your water. Don’t underestimate the power of a good filter, brushing the walls, and a solid pool maintenance routine.

When NOT to Drain Your Pool

Never drain your pool just because the water looks a little cloudy. That’s like selling your car because it’s dirty. Cloudy water is usually caused by a filtration problem or an imbalance in chemical levels—both of which are easily fixable without starting from scratch.

Avoid draining your pool during winter or immediately after a storm. The ground in Northern California stays saturated longer than you might expect, and draining during these times raises the risk of serious damage.

Call in the Pros Before You Drain

If you think your pool really needs a full drain, talk to a pool service expert before diving in. A trained technician can test your water chemistry, evaluate the condition of your pool surfaces, and recommend the safest course of action based on your specific pool type and local conditions.

A Clean Pool Doesn't Always Mean a New Pool

It's easy to assume that the path to clean water means starting over, but more often than not, it just takes a little care and know-how. With regular maintenance, you can avoid getting to the point where draining even feels like a good idea. Weekly service, chemical balancing, and seasonal checkups all go a long way.
