The first step in the weatherization procedure is to make sure your water chemistry is balanced. You should make sure that your pH, Total Alkalinity, and Calcium Hardness are all balanced. By balancing your water chemistry you are protecting the surface of the pool from staining and etching.
Adding a winterizing chemical kit to your water will help keep it blue and clear for the next season. Be sure to follow the manufacturer’s instructions for the kit.
Do not use a floater that contains a strong oxidizer (chlorine or bromine) as the floater will stick against the wall and stain and/or bleach your wall, especially a vinyl liner. For the same reasons DO NOT throw chlorine or bromine tablets into the pool. They will sink to the bottom and damage your pool’s surface.
When water freezes, it expands. This can cause great damage to your pool, pool plumbing, and its filter system. If you are closing up your pool for the winter, you should always take precautions to protect from freeze damage no matter where you live. You can never be sure that it will not drop below freezing, even in the Sun Belt.
Another option for vinyl liner pools is to put an Aquador over the mouth of the skimmer. This is a plastic dam which holds out the water from the skimmer, allowing you to leave the water level up for the winter. This will help in supporting your cover and also help keep the liner from “floating” if the winter is your rainy season.
Blow out the water from your plumbing lines. You can do this using a shop vac. Use the discharge of the shop vac to blow water out of each line from the filter system. As the water is purged from each line, you will need to put a plug in the lines at the pool end. Some fittings will allow for a threaded plug, which is best. Be sure to use a plug with a rubber gasket or “O” ring to make a seal, or the water may fill the line back up. If your fittings are not threaded, then use a rubber freeze plug.
You should cover your pool to keep out the debris. The type of cover you use will depend upon several factors. Our Splash Pool swimming pool covers provide several functions. They can act as a safety device, preventing children and pets from falling into the pool and drowning. They keep dirt and debris out of the pool, particularly in winter. They also reduce evaporation, retain heat, and can provide solar heat gain if using a solar pool cover.
The final step? You must drain all the water from your filter equipment. Please see the filter manual or contact the manufacturer for full instructions on draining the filter or contact your local pool professional.
