Did you know you should only empty a pool once every five years? However, when winter comes around, many pool owners and maintenance staff still choose to remove all the water. This action is not only fairly unsustainable, it can also be very pricey.
There are better ways to keep a pool looking clean and free of insects and algae during the winter months. One of the simplest is to put it into winterising, which consists of keeping the water in good condition during winter and reusing it the next season.
This system entails a considerable saving in both water and money and, if there is frost, prevents damage to the pool such as cracks and holes. Below we go over the five fundamental steps to successfully putting a pool into winterising:
Pool Winterising: Step by Step
- Give the bottom and sides of the pool a thorough cleanse, along with the pump pre-filter and skimmer valves.
- Check the pH level of the pool water and adjust it to between 7.2 and 7.4. You can use pH Minor or pH Plus to regulate the level of alkalinity.
- Apply a shock treatment with triple-action chlorine tablets. It is a good idea to keep the filter running for around 6 hours to guarantee correct product distribution.
- The next day, clean the filter with an extra-strong dose of descaler.
- Finally, add a winter guard and make sure it is well distributed across the whole of the pool.
⚠ For safety reasons and to ensure the pool doesn’t fill with leaves and dirt, during winterising it is highly recommendable to use a cover or canvas. The use of floating covers in domestic pools during periods when the pool is not in use can save up to 65% on maintenance costs (cleaning, filtering) and water loss from evaporation.
- To put a pool into winterising, the water temperature should be under 15ºC.
- To prevent the pool from overflowing during heavy rain, it is a good idea to lower the water level to below the level of the skimmers.
- In places with a frost risk, to stop the water from freezing you can use elements that float on the water (except if you use products such as Inverlong).
