Closing Time: How to Winterize In-Ground Pools in Upstate New York

The process begins with a deep clean. Removing debris and algae is essential to prevent staining and chemical imbalances while the pool sits dormant. Once the surface is clear, Goetz emphasizes the importance of balancing pH and alkalinity levels, as stable water chemistry acts as a primary shield against interior finish degradation during the long off-season.

Water management is the next hurdle. Homeowners must lower water levels to protect skimmers and fittings from the inevitable expansion of ice. However, the most critical phase remains blowing out the lines. By using high-pressure air to force water from returns, drains, and pipes, owners can eliminate the moisture that causes subterranean plumbing to rupture. Each line must then be sealed with winter plugs to ensure the system stays dry.

Finally, attention must shift to the equipment pad and the cover. Pumps, heaters, and filters require thorough draining to prevent freezing, while a tightly secured winter cover acts as the final barrier against snow, wind, and debris. According to Goetz, these preventative habits are not just maintenance chores; they are a necessary investment to avoid costly repairs when the thaw arrives.
