Where you live determines whether or not you should winterize your pool. If your location experiences temperatures that drop below freezing, you’ll need to take steps to ensure that your pool stays healthy. Residual pool water left in pipes can freeze and cause damage. To prevent this from happening, use an air compressor to blow water out of the pool’s plumbing when swimming season is over. Also, drain as much water as possible from the filter and heater. Any remaining water can be eliminated using nontoxic antifreeze (caution: this is different from antifreeze for vehicles). Disconnect the heater, pump and chemical feeders, the latter of which should be cleaned and stored.
Keeping your pool sparkling clean doesn’t have to be as cumbersome as you might think. All pools are different, and so are their maintenance needs. However, they all share one commonality: The secret to pristine pool health is regular, routine care. If you choose to handle common problems like murky water or broken pumps on your own, make sure to always consult manufacturers’ manuals before fixing or using equipment. No matter if you rely on a service company to take care of your pool, you still need to do a few things on your own to ensure your pool stays in good condition for years.
Finally, clean the pool: skim, brush walls, vacuum, empty skimmer baskets, close skimmer line valve, lower water level to approximately 18 inches (45 centimeters) below the coping and supercholorinate. Lastly, cover the pool to keep out debris.
Pool water should be tested regularly to make sure it’s clean and healthy. The pH scale is a measurement of acidity or alkalinity that runs from 0 to 14. A reading between 7.2 and 7.8 is ideal; this range is safe for swimmers and helps sanitizers work at top efficiency.
If a pool is properly winterized, it can easily be reopened come swimming season. Most importantly, don’t remove the pool cover until you’ve cleaned the area around the pool. Sweep or hose away debris to prevent it from getting into the pool. Next, use a garden hose to fill the pool to its normal water level. Reconnect everything that was disconnected. Water will need to flow through the circulation system, so open the skimmer line valve. Test the water for its pH level, then shock the pool. It’ll take a week or more before the pool gets balanced and becomes swimmable. Leave the pump running 24 hours a day, and reduce the run by only an hour or two each day until the water is balanced.
