How to Winterize Your Pool and Protect Against Leaks in Manitoba

Manitoba winters are no joke. When temperatures drop below freezing, your pool faces serious risks. Many pool owners don't realize that improper winterization is one of the leading causes of costly pool leaks and damage. The good news? You can protect your pool from freezing and keep it leak-free with the right approach.

At Leak Detection Manitoba, we've seen what happens when pools aren't properly prepared for winter. After 30 years of experience serving Manitoba and surrounding areas, we know exactly what it takes to close and winterize your pool correctly. This guide will walk you through everything you need to know to winterize a pool and avoid expensive repairs come spring.

Why Does Winterizing Your Pool Matter in Manitoba?

Your pool is a major investment. When you close your pool for the season, you're not just covering it up and walking away. Proper winterization protects your pool from freeze damage, prevents leaks, and saves you thousands of dollars in repairs.

Water expands when it freezes. This simple fact creates massive problems for pool owners. When water in the pool freezes, it can:

• Crack pool walls and surfaces
• Damage plumbing lines
• Break pool accessories and equipment
• Create leaks in vinyl liner pools
• Cause concrete pool deterioration

"We see dozens of pools every spring with preventable damage. Most problems happen because the water level wasn't adjusted properly or the pool wasn't winterized before the first hard freeze," says our team at Leak Detection Manitoba.

The winter months bring freezing temperatures that can destroy an unprepared pool. That's why learning how to winterize your pool correctly is essential for every pool owner in our region.

What Happens When Your Pool Isn't Properly Winterized?

Skip the winterization process, and you're asking for trouble. Here's what can go wrong:

Pool Structure Damage: Frozen water puts enormous pressure on pool walls. Concrete pools can crack. Vinyl pool liners can tear. The pool interior suffers damage that might not show up until you try to fill the pool in spring.

Equipment Failures: Your pool heater, pump, and filters contain water. When that water freezes, it expands and breaks expensive equipment. A single frozen pump can cost hundreds to replace.

Major Leaks: This is where things get expensive. Frozen pipes burst. Cracked pool surfaces leak. By the time you open the pool in the spring, you might discover your water level dropping constantly. That's when pool owners call us for pool leak detection and repairs.

Higher Chemical Costs: A pool that wasn't properly closed develops algae and bacteria throughout the winter. You'll spend more time and money trying to clear the water and balance the water chemistry when pool opening arrives.

How to Close Your Pool: Step-by-Step Pool Closing Tips

Ready to winterize your pool? Follow these pool closing tips to protect your pool and prevent leaks:

Balance Your Water Chemistry

Start your pool winterization about a week before you plan to close the pool. Test and balance the water chemistry:

• pH: 7.2-7.6
• Alkalinity: 80-120 ppm
• Calcium hardness: 180-220 ppm

Balanced water prevents corrosion and scale buildup on pool surfaces during the winter. This step helps keep your pool in good condition and makes pool care easier when you reopen.

Clean the Pool Thoroughly

Remove all debris, leaves, and dirt. Brush the pool walls. Vacuum the bottom. A clean pool means cleaner water when you open the pool next season. Plus, you'll avoid that dreaded green pool situation.

Lower the Water Level

This is critical for Manitoba pools. You need to lower the water level below the skimmer and return lines. But how low should you go?

• For in-ground pools: Drop the water 4-6 inches below the skimmer
• For above-ground pools: Lower to just below the skimmer opening

Important: Never drain the pool completely. An empty pool can pop out of the ground due to groundwater pressure, especially during spring thaw. You need to keep water in the pool for structural integrity.

If you're unsure about your pool's water level, contact your local pool professional. At Leak Detection Manitoba, we help Manitoba pool owners determine the right water level in the pool for safe winterization.

Protect Your Plumbing

Water in your plumbing lines will freeze and cause breaks. Here's how to protect the pool:

• Blow out all lines using a shop vac or air compressor
• Add pool antifreeze to remaining water in lines (use non-toxic pool antifreeze only)
• Remove drain plugs from pumps and filters
• Store pool accessories like ladders and diving boards indoors

Add Winterizing Chemicals

Shock your pool with chlorine. Then add winter pool chemicals that prevent algae growth. These chemicals help keep your water clean throughout the winter months.

What Water Level Should You Keep for Winter?

The water level in the pool is a balancing act. Too high, and freezing water damages your equipment. Too low, and your cover won't fit properly.

Here's a simple rule: Lower the water to 4-6 inches below the skimmer opening for inground pools. This protects the skimmer from freeze damage while maintaining enough water to keep the pool stable.

For vinyl liner pools, never lower the water too much. The liner needs water pressure to stay in place. Drop it too low, and you risk wrinkles or damage to the liner.

Need to fill the pool with more water before closing? That's okay. It's better to have the correct water level than to risk damage from improper winterization.

How Can You Protect Your Pool from Freezing Damage?

Manitoba's harsh winters require extra protection. Here's how to keep your pool safe:

Use Quality Winter Cover: A solid winter cover does more than keep debris out. It protects the pool from snow weight and prevents sunlight from creating algae. Make sure your cover on your pool is secure with water bags or cover clips.

Install an Automatic Pool Cover System: Some pool owners use an automatic pool cover for convenience. These covers provide excellent protection and make it easier to maintain your pool over the winter.

Monitor Water Under the Cover: Use a pool cover pump to keep water from accumulating on top of your winter cover. Heavy water weight can damage the cover and put stress on pool walls.

Consider a Pillow for Above-Ground Pools: An air pillow under the cover during the winter helps distribute ice pressure. This simple pool accessory can prevent serious damage to your ground pool walls.

Should You Use a Winter Cover or Pool Cover?

All covers aren't created equal. Here's what you need to know:

Solid Winter Covers: These block sunlight and debris. They're perfect for keeping the water clear. You'll need a pool cover pump to remove rain and melting snow from the top.

Mesh Winter Covers: These let water drain through while blocking large debris. No pump needed, but some fine debris will get into your pool water.

Safety Covers: These support weight and meet safety standards. They're more expensive but provide the best protection for families with children or pets.

For Manitoba winters, we recommend solid winter covers. They provide the best protection and help keep your water clean. Whatever you choose, make sure it's designed to handle snow loads. Our winters are tough, and your pool cover needs to be tougher.

What Are the Signs of a Pool Leak Before Closing?

Here's a critical tip: Check for leaks BEFORE you winterize your pool. Closing a pool with an existing leak leads to serious problems. Freeze damage will make a small leak much worse.

Watch for these warning signs:

• Water level drops more than 1/4 inch per day
• Wet spots around the pool area
• Cracks in the pool surfaces
• Loose or damaged tiles
• Air bubbles in return lines
• Pump running more than usual

Found a leak? Don't close your pool until it's fixed. A leak combined with freezing temperatures creates a disaster. The water will freeze in the crack, expand, and cause major structural damage to pool from freezing.

"We strongly recommend having your pool inspected for leaks before winterization," advises Leak Detection Manitoba. "It's much easier and cheaper to fix a leak now than to deal with freeze damage in spring."

Winterizing an In-Ground Pool vs. Above-Ground Pool: What's the Difference?

The basics are similar, but there are key differences:

In-Ground Pool Winterization:

• Lower the water 4-6 inches below skimmer
• Blow out all underground plumbing lines
• Add antifreeze to lines below ground level
• Use a solid winter cover secured with water bags
• Consider professional winterization for complex plumbing

Above-Ground Pool Winterization:

• Lower water just below the skimmer
• Drain and store the pump and filter
• Add an air pillow under the cover
• Use a winter cover designed for above-ground pools
• Store pool accessories indoors

Ground pool owners: Your pool is more vulnerable to wall collapse if water freezes inside. Make sure you properly winterize and never drain completely.
