Step 5. Reduced the Swimming pool’s Water Level

If you reside in a cozy, dry climate, you can avoid the next step.
At the end of the period, eliminating some water avoids freeze damages and overflow to a lower level. Ideally, your water level needs to be below the ceramic tile border or the bottom edge of the skimmer if you do not have a tile line, or whichever is lower if you have both.

The exact degree to drain the slim down to is determined by which kind of cover you’ll be using and the type of pool surface area you have. The water helps sustain your body and the weight of any snow or particles that end up on top, so it is essential to adhere to the producer’s referrals.

Plastic Lining. Bring the water to one inch below your skimmer opening or tile line, whichever is lower.

Plaster or Non-Vinyl Pool Lining. Lower the water to 6 inches below the skimmer or tile line if you utilize a solid cover. However, when using a mesh cover (or none, however you want to use a cover), reduce the water to 18 to 24 inches listed below the skimmer or floor tiles.

Be sure the water is no reduced than the skimmer base if you have an automatic pool cover.

Suppose you live in a place where the temperature drops to minus or lower. You are at risk. Residual water can freeze inside your pool equipment and plumbing and cause them to expand and crack.

To avoid such damage in winter, they should be as dry as possible. You can also use a swimming pool antifreeze.

If you live in a warmer climate environment and choose to blow out the lines, you must remove every last little water from the lines, pump, and filter. It may be necessary to purge the lines with an air compressor.

If this is not possible (or highly inconvenient), you can solve the ice problems with antifreeze for the pool.

In above ground pools, draining is easier: remove all hoses and remove the plug from the bottom of the filter. Above ground pool owners are advised to use a pool cushion. Placed in the pool’s center and tied to the sides of the pool, these air-filled rings help prevent pool water from freezing.

Use drain plugs to drain water from the pump, filter, heater, and chlorinator. The water must be drained or purged to prevent your equipment from freezing and cracking.

Pool heater. If you have a pool heater, make sure you drain the pool heater completely, then blow through the lines with an industrial vacuum cleaner or compressor. – Remove all drain plugs and use a vacuum cleaner to purge the pipes. Leave the drain plugs open, but remember where you store them.

A well-made winter pool cover is essential to keep your pool clean when not in use. There are usually two types of winter covers on the market: mesh and solid vinyl.

Mesh covers are more affordable and do not require maintenance in winter, but they can allow debris to enter the pool water. In addition, the mesh panel cover allows water to drain into the pool. You may need to lower the pool water level again during the winter months if rain or snow melts in the pool.

If you intend to use a more expensive alternative than conventional pool safety covers, this can help protect your pool from the elements. Also, protect people and pets from getting under water. A pump is required to remove rainwater and melted snow from above for hard floors.

Be sure to take precautions such as locking the gates of pool fences to prevent a small child or pet from drowning in the water that collects on the pool safety cover before it drains away.

A hard lid that stays in place should keep the pool water clear.

Do Not Be Afraid to Employ Pool Professional.

Although it’s pretty elementary to close your pool, specifically if you’re a seasoned do-it-yourselfer, some components aren’t so straightforward.

After draining the water to winter levels, put antifreeze in the skimmer opening to prevent water from freezing in the pool’s plumbing lines.

How much antifreeze should I add to my pool pipeline?

The standard advice is to use one gallon of swimming pool antifreeze for every 10 feet of 1.5-inch pipe, assuming your pipe is full of water. If you add it to an empty pipe or nearly empty pipe, you can use much less.
