It is that time of year again where we need to get our pools ready for Winter. This can look very different from region to region. It really all depends on exactly how cold Winters are in your neck of the woods. Most people in States where it gets to freezing temps do what is known as “Winterizing” their swimming pools.
When winterizing, it’s important to move pool equipment such as pumps, filters, and other gear indoors to protect them from freezing and damage. What happens if you choose not to Winterize? You are in for some trouble. Here are some of the things that could happen if you do not properly close your swimming pool for those icy Winter months.
You Could Damage Your Swimming Pool Pump
Whether you have an energy efficient variable speed pool pump or a single speed pool pump, the freeezzing water going through it can damage the components. Especially if the water freezes inside of the pool pump. Don't worry so much about the connectors and pvc. If broken,these can easily be replaced. Needing a whole new pump come Spring? That can get expensive.
If your swimming pool pump gets ruined or you are just ready for an upgrade, I highly suggest you check out the American made, household name of Black & Decker who have extended their expertise to the swimming pool industry. They are half the price of what you would pay at your local swimming pool store. Check them out here.https://poolpartstogo.com/collections/all-pumps
You Could Damage Your Filter
Filters can handle normal pressure. Even high pressure from being dirty. However, the pressure of expanding ice is something your swimming pool filter cannot handle. The this can cause the tank to crack, the clamp to crack, or the valve can crack. Then the filter can can begin to leak. It is super easy to Winertize your filter. All you do is open the air bleed assembly and remove the drain plug. With a multiport valve, leave it between two positions. If it is a push-pull slide valve, you will want to leave it halfway up.
You Could Damage Your Pipes if They Freeze
When we Winterize, we lower the watr level and ensure all the water has been blown out of the pipes. Any standing water that you leave in the pipes is bound to freeze. Much like what we talked about in the filter, the freezing water will expand and put a ridiculous amount of pressure on your skimmer, pipes and anything else that can become full of water.
Now the pipes underground can also freeze, but not as quickly. This is due to the insulation from the ground. After several days of freezing temps, you can expect the underground pipes and the surrounding dirt to freeze.
You Could Damage Your Heater
Pool heaters are stronger, but still not strong enough to withstand the freezing temps. To Winterize a pool heater, remove the front and rear header drain plugs and disconnect the pressure switch. Like the plumbing, blow out the lines to remove any water that may be hanging out.
You Could Damage Your Pool Structure
This mostly pertains to above ground pools. They can actually crumple, much like a tin can. This is because as the ice sheets thicken, the outward stress is pushed against the walls. It can also put undue pressure on your skimmer. Additionally, be sure to remove and store ladders during the winterization process to prevent damage to both the ladders and the pool structure.
You Could Damage Your Deck
You could ruin the fun activity of opening your pool if there is a pipe cracked below your deck. This could lead to the headache of a pool deck gut-job. Above ground pipes are much easier to repair. Having to cut through stone sounds like a nightmare to me.
You Risk Water Level Problems
When it comes to winterizing your above ground pool or inground pool, managing the water level is one of the most important steps you can take to protect your investment. If you skip this crucial part of the process, you could end up with a host of problems that go far beyond just a messy pool come spring.
Improper water level can put unnecessary strain on your pool cover, whether you’re using a safety cover or a solid cover. If the water level is too high, rain and melting snow can cause the cover to sag or even collapse under the weight, letting in floating debris and making it harder to keep your pool clean.
On the other hand, if the water level is too low, your cover may not be properly supported, which can lead to tears or allow wind to get underneath and dislodge it entirely.
To avoid these issues, you’ll want to follow several steps before the winter months set in. For above ground pools, it’s usually best to lower the water level by about a foot if you’re using a mesh pool cover, or about six inches for a solid cover.
Inground pools typically require the water level to be dropped 12-18 inches below the skimmer for mesh covers, or 3-6 inches below the tile line for solid covers. Using a submersible pump or a siphon hose makes it easy to drain just the right amount of water—just be careful not to drain the pool completely, as this can cause the ground to shift and damage the pool structure.
Once you’ve adjusted the water level, make sure your pool cover is secure. A properly fitted cover, held in place with straps or weights, will help protect your pool from rain, ice, and wind throughout the winter. This not only keeps out debris but also helps maintain balanced water chemistry by limiting the amount of rainwater and contaminants that can enter the pool.
Keeping the water at the right level is also key to preventing algae and bacteria growth. If the water level is too high or too low, it can throw off your pool’s water chemistry, making it easier for algae and bacteria to take hold. Regularly check your pool’s water level during the winter months, especially after heavy rain or snow, and make adjustments as needed to keep everything in balance.
If you’re unsure about the best way to manage your pool’s water level, there are plenty of helpful YouTube videos and online resources available. And if you ever have questions, don’t hesitate to reach out to a pool professional for advice. Taking these steps now will help ensure your pool is protected all winter long and ready for a smooth opening in the spring.
It is Best to Winterize
Air pillows, skimmer plugs, pool covers, pool antifreeze and a few other important steps ensure you won’t experience any damage to you inground or above ground swimming pool. Check out our blog on how to Winterize a swimming pool for more information.
To ensure a complete winterization plan, start as summer ends and fall begins by monitoring outdoor temperatures—when they drop below 65°F, block out time to begin. The key features of a pool closing kit include pool chemicals, chlorine shock, and clear directions for use.
Begin by cleaning your pool thoroughly: vacuum the bottom, brush the walls, and soak removable plastic parts and accessories in a bucket with cleaning solution, letting them sit before you rinse and store them. Balance your water chemistry, including calcium hardness, and measure the correct quantities of chemicals. Add shock (chlorine shock) and circulate the water to distribute pool chemicals evenly.
Remove hoses, break down equipment, and store items indoors for security and protection. For above ground pools, place an air pillow at the center before covering, and ensure the covering is secure. Some steps or products are optional depending on your pool setup, and the cost of winterization can vary.
Always follow package directions, and purchase a pool closing kit for a complete and secure process. Tap for more information or answers to common questions—a well-executed plan will protect your investment.
See you poolside, come Spring!
