A simple method is to bring down the quantity of water inside the pool to create space for the extra water once it turns into ice. Just look at the amount of water that will have to be disgorged and wasted.
You can drainage and dry out the inside of the skimmer then cover up it or reduce the water in the pool to a degree that is below the skimmer. It goes the same way as an air rest, it engages the pressure of the freezing water. The skimmer guard like a constrict plastic pipe that can be inserted and secured in the skimmer. It also seals the skimmer entry tube so that the water does not get into the pipes and filters.
An alternative is to use a swimming pool air pillow. The air pillow is based and assured at the center of the pool, under the pool cover. This doesn’t block the water from freezing, nevertheless, it absorbs and directs the force of the freezing water towards it rather than on the other parts of the pool. This is will be very efficient on the pool itself, but what about the other parts of the pool that is a distinct water container.
Each of these techniques have their own rewards and restrictions. Take your time to realize each and do which is inexpensive and handy for you.
