How to Cover A Pool For the Winter?

18 minutes read

Covering a pool for the winter is an essential step in pool maintenance to protect it from harsh weather conditions and debris. Here's a step-by-step guide on how to cover a pool for the winter:

  1. Clean the pool: Start by thoroughly cleaning the pool to remove any debris, leaves, or dirt. Brush the walls, vacuum the bottom, and skim the surface to ensure it's free from any contaminants.
  2. Balance the water chemistry: Test the pool water and adjust the pH and chlorine levels to proper levels for winterization. This will help prevent algae growth and staining during the off-season.
  3. Lower the water level: Use a submersible pump or the pool filter's waste setting to lower the water level below the skimmer mouth. This prevents freezing and potential damage to the skimmer and plumbing.
  4. Remove pool accessories: Take out any removable items from the pool, such as ladders, slides, and diving boards. Clean and store them properly to prevent damage over the winter.
  5. Install winterizing plugs: If your pool has skimmers or return jets, insert winterizing plugs into them. These plugs will prevent water from entering these areas and causing freeze damage.
  6. Blow out the plumbing lines: Use an air compressor or a shop vacuum to blow out the water from the pool's plumbing lines. Start with the return jets, followed by the skimmer lines. This prevents freeze damage and keeps the plumbing intact.
  7. Cover the pool with a winter cover: Choose a good-quality pool cover that fits your pool's dimensions. Ensure that it can withstand harsh weather conditions and protect against debris. Place the cover over the pool, making sure there are no gaps or loose areas.
  8. Secure the cover: Use water bags, cover clips, or cable and winch to secure the cover in place. This prevents wind from getting underneath and eliminating the risk of damage.
  9. Monitor the cover: Regularly check on the pool cover throughout the winter to ensure it's in good condition. Remove any standing water or debris that may accumulate on the cover to prevent damage.
  10. Plan for maintenance: Consider using a pool cover pump to remove excess water from the cover. Also, periodically check the pool's chemistry and adjust it if necessary to prevent any problems once the pool is reopened in the spring.


By following these steps, you can properly cover your pool for the winter, safeguarding it from the elements, saving money on potential repairs, and ensuring an easier opening process next swimming season.

How to measure a pool for a winter cover?

Measuring a pool for a winter cover is a simple process that requires a measuring tape or measuring wheel. Here are the steps to measure a pool for a winter cover:

  1. Clean the pool: Before taking any measurements, make sure the pool is clean and free of debris, as it might affect the accuracy of your measurements.
  2. Measure the length: Start by measuring the longest length of your pool from one end to the other. This measurement should be taken along the waterline, not the entire length of the pool. Record this measurement.
  3. Measure the width: Next, measure the widest width of the pool, again along the waterline, and record this measurement.
  4. Measure the depth: Measure the depth of the pool at its deepest point. This measurement is essential as it will determine the height and capacity of the winter cover you'll need.
  5. Determine the overlap: Most winter covers require an overlap over the pool's edges for a secure fit. Refer to the manufacturer's instructions to determine the recommended overlap measurement. Generally, a 12-18 inch overhang is sufficient.
  6. Calculate the cover size: To determine the cover size, add the width and twice the depth measurements to the length measurement. Then add the recommended overlap measurement to each side. This should give you the dimensions of the winter cover you need.


For example, if your pool measures 40 feet long, 20 feet wide, and has a depth of 6 feet, and the recommended overlap is 12 inches, the cover size calculation would be as follows:


Length: 40 feet Width: 20 feet Depth: 6 feet x 2 = 12 feet Overlap: 12 inches x 2 = 24 inches


Cover size: 40 feet + 12 feet + 24 inches + 24 inches = 76 feet


So, in this example, you would need a winter cover with dimensions of approximately 76 feet by 44 feet.


Remember to always check the specific instructions provided by the manufacturer of your winter cover, as recommended measurements can vary.


How to keep an inground pool cover in place during winter winds?

There are several methods you can use to keep an inground pool cover in place during winter winds:

  1. Use water bags or jugs: Fill heavy-duty water bags or jugs with water and place them around the edges of the pool cover. The weight of the water will help keep the cover from lifting or blowing away.
  2. Install wind clips: Wind clips are designed to hold the pool cover securely in place by attaching it to the pool's decking or other fixed structure. Simply clip the cover onto the pool's edge using the provided attachments.
  3. Secure with bungee cords or ropes: Anchor the pool cover using bungee cords or ropes. Attach them to the grommets or loops on the cover and secure them to nearby fixed objects such as fences or heavy pots filled with sand or rocks.
  4. Invest in a winter cover with an anchoring system: Consider purchasing a winter cover that comes with an anchoring system. These systems consist of straps or cables that run across the pool cover and are anchored to the pool's decking or surrounding structures.
  5. Use cover seals: Cover seals are inflatable air pillows that you place beneath the pool cover. They prevent the cover from sagging or pooling water, which can be prone to wind damage. Additionally, they help keep the pool cover in place during strong winds.


Remember, it's important to regularly inspect and maintain your pool cover throughout the winter season to ensure it remains secure and intact.


How to protect a pool cover from animal damage?

To protect a pool cover from animal damage, you can take the following measures:

  1. Install a fence or barrier: Create a physical barrier around your pool area to prevent animals from entering. This can be a tall fence, a mesh or wire enclosure, or any other type of barrier that is suitable for your pool.
  2. Use animal repellents: Apply animal repellents around the pool cover area. There are various commercial repellents available that are specifically designed to deter animals. These repellents emit odors or sounds that animals find unpleasant and help to keep them away.
  3. Remove attractants: Animals are often attracted to the pool area due to food sources or shelter. Keep the pool and surrounding areas clean by removing any fallen fruits or food scraps that may attract animals. Additionally, trim back any bushes or vegetation that provide hiding spots or easy access for animals.
  4. Secure the pool cover: Make sure the pool cover is securely fastened and tightly secured. Use strong and durable cover fasteners or straps to hold the cover in place. This will make it less likely for animals to crawl or walk on the cover, reducing the risk of damage.
  5. Use deterrents: If animals persistently attempt to damage the pool cover, consider using visual or sound deterrents. These can include reflective tape, inflatable scare devices, or ultrasonic devices that emit high-frequency sounds that animals find irritating.
  6. Regular inspections: Regularly inspect your pool cover for any signs of damage or wear and tear, which could potentially be caused by animal activity. Promptly repair any damages to prevent further problems.
  7. Secure access points: If you have a motorized or automatic pool cover, ensure that the access points are properly secured when the cover is closed. This will help to prevent animals from entering or damaging the pool cover mechanism.


Remember, it's important to identify the specific animals causing damage and tailor your approach accordingly. Removing attractants, using deterrents, and maintaining a secure cover will significantly reduce the risk of animal damage to your pool cover.
