winter pool maintenance This article talks about winter pool maintenance tips, and advice for which problems you should be watching for with your swimming pool over the winter season. If you live in an area that does not get cold enough to worry about water freezing then you do not really "close" the pool, so much as you put it on a minimal maintenance schedule. So long as you scoop the leaves, vacuum the bottom, and keep some chlorine in the water, then the pool will most likely stay clear. Cool weather causes less chlorine consumption, as well as slower bacteria and algae growth, and if the weather is too cold to swim then there is no appreciable bather load either. Cool weather pools that operate during the winter season simply need to keep the water circulating and filtering, and continue to perform the same maintenance as during the swimming season...just much less than when the pool is beinng used regularly.


So what about winter pool maintenance in cold climate areas? Places that deal with rain, snow, ice, and fluctuating temperatures experience far greater wear and tear on outdoor swimming pools as compared to cool climate pools that are still essentially open and operating year round. The defining factor is how cold the winter is in your area. If your winter temperature stays above freezing then you have the option to keep the pool open. If winter temperatures typically fall to zero or lower then you must winterize your pool and close it completely until spring. If this is a subject you want to know more about you can watch this video blog series I made that discusses how to winterize each component of your pool.


So now your pool is winterized - is that it until spring?

In theory, if you have done a good job winterizing your pool you should be able to walk away completely until the warmer weather arrives in the spring, at which time you open your pool. There are however some certain situations that can happen to your pool over the winter season that can result in damage to your pool - even if you have correctly winterized it. You would be well advised to periodically check on your pool during the winter in order to monitor things like the water level. If your pool has a pre-existing problem, or developed a problem after you closed it, your pool could be losing water and the cover could be hiding this from you.


Pool Water Level - You should regularly check on the water level in your pool during the winter season. Depending on what type of pool cover you have it can be difficult to see a dropping water level in the pool once the cover is on. If your pool drains without your knowledge in the winter then this will almost certainly result in a major failure of your pool structure, regardless of whether you have a concrete pool, fiberglass pool or vinyl liner pool. If you have an isolation cover like a tarp, the water level in the pool should remain constant over the winter. If you have a porous cover like a safety cover then the water level in your pool should rise over the winter as rain and snow makes its way into the pool. In addition to watching for leaking water, it is equally as important to monitor for raising water levels. Snow, ice and rain can add to the water in your pool and if the water level rises too high this can start to cause problems. An overfilled pool will allow water to leak out as the water level goes above the designed waterproof level. This water itself can cause damage slowly over time as it moves, however a much greater concern is water overfilling your pool and then experiencing a cold snap in the weather. An overfilled pool combined with a sudden re-freeze is a recipe for disaster. One of the most important points of winter pool maintenance is to take advantage of warmer stretches of weather when you can use a small submersible pump to lower the water level in the pool to normal winterized ranges and prevent it from overflowing. Lowering the water level below the mouth of the skimmer would be a good finishing point for draining down an overflowing pool - you do not want to drain too much since many pools need a high water level to help stabilize them in the ground. Just be sure to pump the water well away from the pool location!


Pool Cover Maintenance - You should regularly check on the integrity of your pool cover over the winter season. Tarp and waterbag covers in particular need to be checked often so that you can replace failed water bags before your cover falls into the pool. Waterbags are notorious for breaking easily, or developing holes from small critters like squirrels walking on top of them. Be sure to keep a small contingency of waterbags on hand at all times in the winter so that you can replace them as needed. You should only fill a waterbag 1/2 to 2/3rds of the way full with water as this allows room for expansion when the water in them freezes. With a tarp and waterbag system another winter concern you should watch out for is larger twigs, sticks or branches that fall onto the cover. These sharp objects can easily rip holes in paper-thin tarp pool covers so be sure to remove debris from in and around your pool as you notice it. If you have a safety cover on your pool then you might want to periodically use your maintenance pole and brush to pull snow off of the cover. Safety covers are strong, and designed to take snow loading, but it is still possible to stretch out the steel hardware and cause rips in the straps and cover sections. This is even more important if you have a solid safety cover as opposed to a mesh safety cover which will allow the snow to melt into the pool.


Pool Heater Winter Maintenance - Since the pool heater is typically the most expensive piece of equipment on the equipment pad, logic dictates that you want to do everything you can to protect it from damage. Unfortunately pool heaters tend to develop pests over the winter season. If you need more information about the winterizing process you can read this article about how to winterize a pool heater. It used to be that pool heaters were all standing pilot operated with no electrical components. Modern day pool heaters all require an electrical control circuit at minimum. If you have a digital pool heater then be absolutely certain that you turn off the electrical breaker that feeds the heater. Many pool owners just have the heater turned off at the control panel, but if there is still power reaching the heater then the internal electrical transformer will be energized. An energized transformer produces heat. If you leave a tiny space heater running inside of your pool heater during the winter then do not be surprised if some little creature moves into this cozy home during the colder months.


Adding Chemicals In The Winter - For the most part, if you have winterized your pool correctly including raising the chlorine levels, you should not need to add extra chemicals during the winter season. That being said, if you struggle with your pool being green every spring, you might benefit from adding some chemicals to help keep the green water at bay. As much as it would help your pool to add some liquid chlorine, without the pump and filter running the chlorine will not diffuse properly and can accumulate on the bottom of the pool and potentially bleach the color from your liner. So instead of adding chlorine, I prefer to use pool enzymes to help eat some of the organic debris that is in the water. Adding a very small amount of pool enzymes will not likely cause any problems with staining or bleaching of the liner, but will certainly help to keep the water as clear as possible until the spring. Especially if you have a mesh safety cover, which are known for allowing the water to turn green before spring, dosing with a pool enzyme product two or three times over the winter season would be a great idea. Many safety covers even have a cap installed in one panel such that you can unscrew it...and now you know what that is for! Simply unscrew the cap and add a dose of pool enzymes. It is not a perfect system guaranteed to keep your water clear until spring, but it will absolutely help.
