As the summer season winds down into the so-called "shoulder season"—that period between peak season and offseason—pools in cooler climates are ready to be winterized. Here are four reasons why this is the ideal opportunity to ensure water features are properly put to bed or ready to answer the wakeup call as business resumes.
1. Repeated Expansion and Contraction Cause Cracks To Grow
Cracks are a magnet for mold and mildew in warmer areas and for freezing in colder climates. Once moisture gets in, it has a hard time getting out. Check the walls and floors of pools and tanks for signs of cracking or other imperfections. Pipe connections are also a common source of cracks and leaks. For exhibits and pools that feature acrylic walls, closely inspect sealant at the joints for signs of damage that could cause or has started to leak.
2. Keep Filters and Filter Baskets Free of Leaves, Other Debris
With falling leaves and wintery winds, or heavy rainfall and seasonal floods, it may take extra effort to keep pool areas free of debris. Inspect pump and filter equipment for any signs of leaks or damage and make sure they’re operating optimally to take care of the extra burden of fall.
3. Test Systems
This is a good time to test systems. Check and test timers to make sure they are still accurate and reflect the switch to daylight savings or standard time. If pools, tanks or outdoor areas are closing, ensure breakers, pool lights, and time clocks are turned off. Remember to inspect all covers to ensure they have not suffered any damage.
4. Adjust the Chemical Balance for Increased Use or Winterization
Chlorine can break down under the sun’s powerful UV rays so be ready to adapt. Test to check total dissolved solid and cyanuric acid levels. The ideal time to do this is when temperatures are cooler to reduce the risk of excessive evaporation and damage to surfaces from sun and heat.
5. Watch Water Levels
Never drain a pool completely for winter; this can damage the walls and liner and may cause cracking. Water should only be drained to below the skimmer to prevent water from entering the pool equipment, freezing and causing damage. Conversely, as it gets hotter, watch for excessive evaporation and damage to surfaces from sun and heat.
6. Check for Clarity
If pools and water features incorporate acrylic viewing windows and design elements, assess the acrylic for clarity and have them professionally polished to highlight their aesthetic appeal. This can be done when the pool or tank is emptied for maintenance or underwater while it’s still full.
The change in seasons may signal the end of visitors or just the beginning. Regardless, it’s an opportunity to schedule extra time to check water features, exhibits, tanks and pools for early signs of trouble, reset chemicals and systems and perform timely maintenance.
