Pool Losing Water Overnight? How to Solve Water Loss Mysteries in Manitoba

Is your pool losing water overnight, leaving you worried about water bills, pool repairs, or even damage to your swimming pool? If you’ve noticed a drop in the water level that’s more than just a splash, you’re not alone. Pools across Manitoba can lose water overnight for a variety of reasons—including evaporation, leaks, and equipment problems—but knowing the difference can save you time, stress, and money. In this post, we’ll show you why your swimming pool might be losing water, how to spot and solve pool leaks, and how Leak Detection Manitoba, using Leaktronics’ leading leak detection equipment, can help local pool owners keep their pool in top shape.

Why Would a Pool Lose Water Overnight in Manitoba?

Pools can lose water for different reasons: evaporation, structural leaks, plumbing leaks, or problems with pool fittings. Losing a small amount of water overnight can be normal, given Manitoba’s temperature swings and dry nighttime air, but significant or sudden drops in your pool water level are red flags.

Sometimes the pool is losing water because of hidden cracks, old fittings, or a faulty pump system. It’s important to identify the true cause of overnight water loss before it becomes a bigger issue for your pool and wallet.

How Much Water Loss Is Normal in a Pool?

On average, pools in Manitoba will lose about 1/8 to 1/4 inch of water per day to evaporation. That’s around a bucket with water left out overnight—barely enough to notice on your pool’s water level. But if you find your pool loses more than 1/4 inch, or several gallons of water overnight, you may have a leak.

Monitoring your pool water loss over a few days can help you determine what’s normal. If water loss increases or remains excessive, a professional leak inspection is recommended.

Could Evaporation Be Causing Pool Water Loss?

Evaporation is a natural process, especially when the water temperature is high and humidity is low. Factors that make pools evaporate faster include:

• Lack of a pool cover
• Heated water and heat loss at night
• Wind and low humidity
• Water features like fountains or spas

A pool losing water overnight due to evaporation will show gradual, not sudden, changes. Pools can lose more water during hot and windy Manitoba days, but sudden overnight drops usually indicate something more serious.

What Are the Main Signs of a Leak?

Not sure if it’s evaporation or a leak? Look for these signs:

• Sudden or excessive loss of water overnight (more than normal evaporation)
• Wet spots, mushy ground, or puddles around the pool
• Air bubbles in the skimmer or return line
• Cloudy water or unexplained drops in water quality
• Water loss even when the pump and filter are off

A steady drop in inches of water or any unexplained water overnight suggests a pool leak is likely.

How Can I Tell if My Pool Is Losing Water Because of a Leak?

Try the bucket test:

1. Place a bucket with water on a pool step; mark water levels inside and outside the bucket.
2. Run your usual pool routine.
3. After 24 hours, compare drop rates. If the pool loses more water than the bucket, you likely have a leak.

Pay close attention if your pool loses water every night, not just on hot days. Leaks tend to result in continuous and often accelerating water loss.

Is a Vinyl Liner More Likely to Leak Overnight?

Vinyl liner pools are popular in Manitoba but can be susceptible to tears, pinholes, and leaks around fittings or seams. Even small holes in a vinyl liner can let out gallons of water overnight, making it hard to keep your pool water level stable.

Regularly check your liner for wrinkles, bubbles, or discoloration—these could indicate water loss behind the vinyl liner. Early detection helps prevent costly structural damage and unnecessary water loss.

How Do Pool Leaks Affect Water Bills and Pool Care?

A leaking pool is expensive—not just the wasted water, but also the increased need for chemicals to maintain water balance, higher energy use to heat new water, and greater risk of structural issues around the pool.

In Manitoba, where water bills can rise sharply, losing gallons of water each night adds up fast! Even a small leak in your pool’s structure or pump system can cause significant water loss—and a big surprise when the water bill arrives.

What Steps Can I Take for Leak Detection at Home?

Here’s how to check for leaks before calling a pro:

• Watch your pool water level daily and mark the water level on the side of the pool.
• Review spots around the pool for evidence of wet ground or puddling.
• Listen for air in the pump system or visible air bubbles.
• Inspect your skimmer, fittings, and pool structure for cracks.

If the loss of water is still unexplained, professional leak detection services with advanced equipment will find the exact source.
