Since PVC pipes are durable and can withstand harsh weather conditions, they should be thoroughly inspected to make sure they’re dry and prevent further damage.
1. For above-ground swimming pools, the process of winterizing involves using an air blower and a vac. Make sure that everything is in place before you go. This includes making sure that your circulation system is off.
2. Using a ShopVac or an air blower, aim it to blow air into a pipe and through the plumbing of a skimmer. This will keep the lines protected this winter. If your system is more complex, you can also use air through your return lines. Just remove the inlets from your pool wall and then blow air through them.
3. If you don't want to remove anything from your system, you can still use pool-grade antifreeze to prevent it from freezing. One gallon of antifreeze is enough for about 10 feet of pipe. But, remember, these are toxic chemicals and are made for cars and not for swimming pools.
4. Since your pool antifreeze has accumulated in your pipes, it’s time to make sure that the water is not reintroduced. You’ll also want to remove the various components that are connected to the return fitting.
