In New England, pool owners often notice changes in water levels, especially during fall and early spring. While some water loss is expected due to evaporation, understanding typical evaporation rates can help you determine if what you’re seeing is normal or if there’s a potential leak.
Typical Evaporation Rates in New England
Under normal conditions, a pool in New England may experience water loss due to evaporation, which can vary from 1/8 inch to 1/4 inch per day. Cooler, dry nights paired with temperature differences—such as when your pool is heated during brisk evenings—can contribute to higher evaporation rates.
Environmental and Usage Factors Impacting Evaporation
Evaporation isn’t solely influenced by temperature; environmental conditions and pool usage play major roles as well:
1. Exposure to Wind
A pool situated on a hillside or in an open area with significant wind exposure will experience increased evaporation. Wind accelerates water loss, as it sweeps away the evaporated water vapor, allowing more water to evaporate continuously.
2. Excessive Pool Heating
When a pool is heated, especially to temperatures significantly warmer than the ambient air (common in the early spring or fall), the rate of evaporation can increase. Warm water evaporates more quickly, particularly when exposed to cooler night air, leading to faster water loss.
3. The Importance of Pool Covers
One of the simplest ways to mitigate evaporation is by using a pool cover. Covering your pool when it’s not in use can significantly reduce evaporation by trapping in the water’s warmth and limiting exposure to wind. This small step can make a big difference in maintaining your pool’s water level and lowering water bills.
When to Be Concerned
If you notice water loss that seems excessive, it may be worth investigating for potential leaks. Factors like excessive exposure to wind or heat can increase evaporation, but a higher rate of water loss could indicate a problem beyond natural evaporation.
For peace of mind, consider reaching out to a professional pool leak detection service. Properly diagnosing water loss early can save you from expensive repairs down the line and ensure your pool is in top shape.
