When it comes to winterizing pools, experienced service techs often have a few tricks up their sleeves that go beyond the standard steps. One common trick is the use of pool pillows or inflatable devices placed under the cover. These are often used in regions with heavy snow or ice, and they help to prevent the pool cover from sagging or sinking under the weight of snow and rain. The pillow creates a dome-like effect, ensuring the weight is distributed evenly and reducing pressure on the cover and the pool structure.

Another interesting technique is the use of rubber expansion plugs in the pool’s skimmers and return lines. These plugs not only seal the lines from water but also provide extra give when the temperature drops. Because they can expand slightly, they allow for a little movement in case there’s any ice formation in the lines. This small detail can make a big difference in preventing cracks in the plumbing during extreme cold.

Some techs go a step further by using Teflon tape on all threaded fittings when disassembling equipment like pumps, filters, and heaters. This ensures that fittings won’t seize up over the winter due to moisture or corrosion, making it much easier to reassemble everything in the spring. Additionally, many pros use a little silicone lubricant on O-rings and seals before storing equipment, which keeps the rubber supple and prevents it from cracking over the winter.

In regions where winter is long and harsh, some techs employ a technique known as double-covering. This involves using both a traditional winter pool cover and a mesh safety cover. The mesh cover goes on first, acting as the primary barrier for debris, while the solid winter cover sits on top, preventing any light from entering the pool. This two-layer approach not only keeps the pool cleaner but also ensures the water chemistry stays stable longer.

Some service techs like to leave a small amount of non-toxic antifreeze in critical areas like the pump basket and skimmers, even after blowing out the lines. This is done as a safeguard in case the temperature 1/16/15 5:18 PM Page 1

drops suddenly after the pool has been closed. Because antifreeze stays in place and prevents freezing in small, vulnerable areas, it adds an extra layer of protection during unpredictable winter weather. These little tricks can make a big difference in keeping a pool safe during the off-season and reducing the amount of work needed when reopening in the spring.
