Falling leaves and dropping temperatures are surefire signs that it's time to prepare your swimming pool for winter. While many pool owners believe they need to drain all the water for the season, experts say this is a common mistake. Leaving water in place is a vital component of the winterizing process for both in-ground and above-ground pools.

Why Should I Leave Water in the Swimming Pool During the Winter?

Since water expands when it freezes, some pool owners believe keeping the pool full will cause damage. However, this liquid is your pool liner’s greatest defense against cracking and splitting. Even with a properly applied pool cover, the liner can contract and rupture due to drastic changes in outdoor temperatures.

Keeping a swimming pool full also prevents discoloration. At the end of the season, you need to balance the water and halt microorganism growth with multiple chemicals. These products prevent the buildup of algae, mildew, and mold that would otherwise permanently stain the pool’s lining.

How Much Water Should I Leave in the Swimming Pool?

While water in the pool protects the liner all winter, it can have the opposite effect on the pipes. The water needs to be drained below the level of the pool skimmer, so it doesn’t enter the plumbing system and freeze in cold weather. Both in-ground and above-ground pools need the fluid level reduced to at least 1 inch below the skimmer line, but 2 to 4 inches will balance out heavy winter precipitation and snowmelt.
