How to Keep Your Pool Maintained All Winter Long

You might not think much about your swimming pool during the chilly Ohio winters, but proper pool maintenance is important all year long. By focusing on proper pool maintenance during the winter, you can protect your investment and ensure that your pool is ready to use when the winter warms up. These are some of the steps that you can take if winter pool maintenance is important to you and your family.

Have Your Pool Checked Out

Now is not a bad idea to have your swimming pool checked out by a professional. If you and your family experienced any problems with your pool during the summer, such as if you think there is something wrong with your pool filter or if your pool liner is damaged, then you may want to have the problem assessed and repaired right now.

After all, if you can get your pool in tip-top shape now, you will be able to put it to use as soon as the weather warms up instead of having to wait to have it repaired. You can also make sure that your pool is in good enough shape that it will make it through the winter without any major problems.

Even if you don’t choose to repair your pool before winter, you will at least have an idea of what is wrong with it. Then, you can budget and plan for any repairs that will need to be done in the springtime, which will help you avoid any nasty, expensive surprises when you least expect them.

Drain Out Some of the Water

You probably don’t want to drain all of the water out of your swimming pool for the winter. After all, you might not want to waste water when re-opening your pool for the spring and summer in a few months. However, you may want to think about draining a little bit of water out of your pool. You can drain the water so that the water line falls a few inches below the pool skimmer to prevent freezing. It is also important to drain any water out of your pool heater, pump and filter. This will help you protect these valuable, important parts from freezing-related damage during the winter.

Add the Right Products

As a pool owner, you probably already know that using the right chemicals and products can help you keep your pool in great shape. It’s not just important to maintain the right chemical levels in your pool when you and your family are using it; it’s also smart to add the right chemicals during the winter months, too.

An algaecide will help you prevent algae from growing in your swimming pool on warmer winter and early spring days. You will also need to make sure that chlorine levels are right for keeping your pool water nice and clean. Avoid adding too much chlorine, though, since this could bleach your pool liner over the long winter. Also, remember to check your pool’s chemical levels at least once in the middle of the winter; you might find that you will need to add additional chemicals to keep your pool clean and algae-free until it’s time to reopen it. Remember that your swimming pool professional will be able to help you with these maintenance tasks.

Keep Your Pool Covered

Pool Cover

As a pool owner, you should know about the value of a good pool cover. If you don’t already have one, it’s worth it to look for a good-quality pool cover as soon as you can. Make sure that it’s the right size for your pool; it should fit snugly and securely but should cover the entire pool. Also, make sure that it’s thick and durable; you probably will not want to replace your pool cover too frequently if you can avoid it, and you’ll want to make sure that it does a good job of protecting your pool. Lastly, look for a pool cover that is easy to put on and take off; you will be happy that you made this a priority later on.

As soon as you close your pool for the winter, it’s time to put your pool cover on. The pool cover will help prevent snow, ice and rainwater from filling your pool. It will help you keep the chemical levels in your pool where they should be, and it will help you avoid having to clean limbs and debris from your pool throughout the winter months.

Although you might hope to put your pool cover on and forget about your pool until the weather warms up, you will need to check the cover from time to time. If you don’t clean it off throughout the winter, you have to worry about limbs, snow and debris adding too much weight and causing damage to the liner. Luckily, quickly cleaning it a few times throughout the season should keep it in good shape.

Also, remember that you can use your pool cover during other times of the year, too. For example, even after you reopen your pool for the summer, you can cover it with your pool cover when it’s not in use. This helps with safety, prevent water evaporation and helps keep your pool nice and clean.

Open Your Pool as Soon as Possible

You might be looking forward to enjoying your pool when the weather warms up, but you might not have thought ahead much about opening your pool. It’s smart to go ahead and stock up on chemicals and other essentials now so that you can open your pool for the season as soon as the time comes.

Believe it or not, it’s actually best to open your pool as soon as the temperatures start to rise in the late spring. Not only will this allow you and your family to get more enjoyment out of your swimming pool, but it will also help prevent algae growth once temperatures start to rise.

Preparing your pool for winter and keeping it in good shape until summer might seem challenging, but it’s not as hard as you might think.

 As the leaves fall and temperatures drop, December marks the time to think about closing your pool for the winter season. Here at Omni Pools & Scapes, we understand that proper winterization is crucial for protecting your pool and ensuring it's ready for use come spring. Here's your step-by-step guide to shutting down your pool the right way: Why Winterize Your Pool? Winterizing your pool isn't just a tradition; it's essential for: Preventing Damage : Ice can expand and crack your pool's structure or equipment. Avoiding Algae and Bacteria : Cold weather doesn't kill all microorganisms, so proper chemical treatment is necessary. Maintaining Water Quality : Ensuring your pool water remains balanced during winter minimizes the effort needed to reopen it. Step-by-Step Winterization Process: Balance the Water Chemistry: Test for pH, alkalinity, calcium hardness, and chlorine levels. Adjust as necessary to keep your water in balance, which helps in preventing algae and scale during the off-season. Clean the Pool Thoroughly: Remove leaves, debris, and vacuum the pool to leave it clean. Brush the walls to dislodge any dirt or algae. Clean or backwash your filter to ensure it's not clogged with debris from the season. Lower the Water Level: For pools in colder climates like Ohio, lower the water level below the skimmer and return lines to prevent ice damage. However, for pools with an auto-cover, maintain a level that doesn't interfere with the cover's ability to seal. Drain and Store Equipment: Drain the pump, filter, heater, and any other equipment to protect from freezing temperatures. Follow manufacturer guidelines for storage. Remove and store ladders, diving boards, and other accessories in a dry place to prevent rust or damage. Add Winterizing Chemicals: Use a winterizing kit or add chemicals separately to prevent algae growth and maintain water clarity. This typically includes: Shock treatment to kill off any remaining algae and bacteria. Algaecide to prevent growth during winter. Sequestering agents to prevent staining from metals in the water. Install the Pool Cover: For above-ground pools, a solid cover is essential. For in-ground pools, mesh or solid covers can be used, depending on your preference for water management during winter. Ensure the cover is secure and tight to keep out debris and to minimize water accumulation on top. Circulate Water One Last Time: Run your pump with the winterizing chemicals to distribute them evenly. Then, shut down your system. Protect Against Freeze: Use pool antifreeze in skimmer and return lines to prevent freezing and damage. Consider a pool heater or invest in a freeze protection system if you live in an area with extreme cold snaps.
