How to Winterize and Close an Inground Pool

Whether you have an inground pool or an aboveground pool, there are certain steps you need to take in order to winterize and close your pool. The first step is to test the water chemistry of your pool and determine what changes need to be made. After testing the chemistry, you can then begin to expel water from the main drain line. Next, place water bags or winter cover blocks around the edge of your pool. You will also want to install a blower to ensure the water is not escaping through the drain lines. In addition, you should also consider installing Algacide, a chemical that helps to prevent algae from growing in your pool.

Place water bags or winter cover blocks around the edge of the pool

Whether you have an inground or above ground pool, you should consider placing water bags or winter cover blocks around the edge of the pool. Not only does this prevent dirt and debris from getting into the pool, but it also keeps the cover in place.

Water bag covers are available in single or double chambers and come in 8′ or 10′ lengths. They are a cost-effective choice for most above-ground pools. Fill them with at least half of their capacity and place them around the edge of the pool.

Water tubes are another good choice for inground pools. They come in a variety of sizes and styles, so you can choose the right size to fit your pool. They are also available in double chambers, which lay flatter and offer added security.

Water tubes can also be filled with a garden hose. You should only fill them halfway to avoid damage. If the water inside the tubes is overfilled, the tubes may burst. You should also keep an eye out for wild animals.

If you have an above ground pool, you can also use air pillows. These inflatable pillows are easy to inflate using an air pump. You can tie them to the base of the diving board or other stationary objects. They relieve the pressure on the ice and make water removal easier. They can also be tied to the diving board base and rope anchors. They are also useful for windy areas.

If you live in a windy area, you may want to use an end-to-end method instead of placing water tubes around the edge of the pool. This allows the cover to remain in place for moderately windy days.

Expel water from the main drain line

Getting a good seal on the main drain plug can prevent water from leaking into the pool even if the pump is off. This is why it is a good idea to take steps to expel water from the main drain line when closing an inground pool.

The main drain is the primary method by which water is sucked into the pool’s pump. The water is then passed through the filter, where it is cleaned of microscopic debris.

The main drain’s other cousin is the skimmer, which collects debris and floatable items before removing them. It is important to make sure that a pool’s skimmer is clean before closing it. It has been known to cause drownings.

To blow the main drain line of the pool, you will need an air compressor. You can also use an auto vac system to do the job. This type of pump works on the same principle as a shop vac, but is a lot more expensive. You can also use duct tape to prevent water from entering the plumbing.

The main drain is usually located at the bottom of the pool. Most pools will have a cover that slants toward the drain. Typically, these drains will be covered with an antivortex cover. You should also take steps to prevent swimmers from playing with the main drain.

The main drain’s other cousin, the skimmer, is a good example of the old adage: “If it sounds too good to be true, it probably is.” This device is a good way to expel water from the main drain line.

Install a blower

Having a blower to winterize and close an inground pool will save you time and money in the spring. Winterizing your pool is a good way to keep the water in your pool from freezing, which can cause damage to the pipes. A blower can help you get the job done without breaking a sweat.

Winterizing a pool can be a daunting task, but it’s important to do it properly to protect your pool investment. Properly winterizing your pool can save you hours of work when the weather warms up in the spring. A good blower is the best tool to help you get the job done.

A good blower should be low pressure, and the right one will have the power to remove all of the water from your pool pipes. It’s also important to blow out the water from your return lines. Depending on the size of your pool, you might need a blower for both lines.

A good blower will have an air hose attached that will blow air back into the pool. This is the easiest way to clear your pipes and will help prevent ice from building up.

The air hose should be placed in the impeller housing or volute on the pump. It should then be sealed with a pump basket. It’s important to make sure that the air hose is connected to the pump so that it can’t blow out the pressure side of the water feature.

You should also consider installing a winterizing plug to make sure that your pipes don’t freeze and leak. These plugs will allow water to drain out of the pipes, and prevent water from getting into the equipment, which can cause major damage when you open the pool in the spring.


Whether you own an inground pool or an above ground pool, it is important to winterize your pool before the winter season. This will keep your pool clean and ready to use in the spring. Also, the lower temperatures of winter will keep the water clearer.

It is important to test the water’s chemistry before closing the pool. The water’s alkalinity should be between 100-150 parts per million. The pH should be between 7.4 and 7.6. The chlorine level should be between 1 and 3 parts per million.

One of the best ways to prepare your pool for winter is to add a shock treatment to the water. Shock treatments will destroy algae and other contaminants, making your pool safer to use in the spring.

Another trick to keep your pool clean is to add anti-freeze to the pool’s pipes. This will help keep the water cleaner and make it easier to maintain the pool throughout the winter.

Keeping the cover in place will also keep out debris. It should be tied securely at two points. You may also want to invest in air pillows for the pool. These pillows will help keep the cover from breaking. You may also want to add tubes or balls.

Winterizing a pool is a simple task that requires minimal maintenance. It is also a great way to save money. You can even hire a pro to do the work for you. If you are not sure about the steps to take, you can check with your local codes department. You can also purchase a winterizing kit from your pool store.

Test the water chemistry

Keeping your swimming pool water in good chemistry is essential to maintaining a healthy pool and keeping your family safe. It can also help to save you money.

The chemistry of a pool can be affected by changes in the weather, landscape, and chemicals. Test your water chemistry on a regular basis. By staying on top of your readings, you can avoid headaches associated with alkalinity and sanitizer imbalances.

Keeping your pool water in good chemistry can prevent damage to your pool equipment and surfaces. The pH, alkalinity, and calcium hardness are important factors to keep your pool safe and healthy. You can test for these levels with liquid test kits, test strips, or a digital test kit.

Pool test kits use liquid reagents to determine the level of chlorine, alkalinity, and pH in your pool. Some test kits are more accurate than others. Some kits are designed for specific pools.

Test strips are simple to use. They test for alkalinity, pH, chlorine, and salt. You can buy them at your local pool store or online. The best thing to do is to follow the directions on the package.

Whether you choose to test your pool water using test strips or a liquid test kit, you should store the chemicals properly before use. It is important to keep the chemicals dry and well-ventilated. If you need to test more than one area of the pool, you should use multiple kits.

You can purchase specialty strips to test for copper, iron, cyanuric acid, and salt. The reagents should be shaken before use. You should also store the tester away from children.
