Pool Loses Water Overnight If you use a heater, your pool warms up and evaporates more water. As the summer air stays warm overnight, your pool will evaporate even faster. Keeping your pool covered can help keep water and heat from escaping into the air.
Why would a pool lose water overnight?
If your pool lost water overnight and it is more than the quarter-inch due to evaporation, you probably have a leak. Evaporation accounts for a minor amount of water lost each day. Losing a half-inch or more overnight indicates a problem.
Can a pool lose water at night?
The differential that occurs between the pool water temperature and the air temperature on late summer nights causes water to evaporate at an accelerated rate. In some cases you might see a water level difference of 1-3 inches overnight. Depending on the size of your pool, that can be over 500 gallons of water loss!
How can I tell where my pool is leaking?
Check the waste or backwash line for water consistently running. One inch of your pool water can equal 500 gallons. Check downhill from a pool, looking for weepers where underground leakage is surfacing. Check for soft or wet spots in the yard, on the side of the pool where the plumbing returns water to the pool.
How do I know if my pool is leaking or evaporating?

Is it normal for a swimming pool to lose water?
Pools lose water gradually, so water-loss can often be left undetected until it escalates into a serious problem. It’s natural for pools to lose water due to evaporation, varying in speed depending on the humidity, temperature, wind conditions, use of pool heater, or the rate of use of the pool.
How much water should a pool lose overnight?
Pool Is Losing 1 Inch of Water Per Day
Losing more than ½” of pool water per day indicates you likely have a leak in your pool’s structure or your pool pump system. You should call your pool service for a thorough leak inspection.
Why did my pool drain itself?
You should know that your pool will lose some water through a number of normal means: splash-out during use, backwash waste, and evaporation. Depending on the climate where you live, you may gain some of that back via rainwater.
How much water evaporates in a pool overnight?
A pool that remains uncovered for 24 hours or more will lose a quarter-inch of water during hot, dry weather. Heat rises as the air cools at night. A good cover will hold in the heat and the moisture at night.
How do I stop my pool from evaporating?
RECOMMENDATIONS TO MINIMIZE WATER LOSS
The number-one way to combat evaporation is with a pool cover. It’s estimated that a pool cover will reduce evaporation by 95 percent. Solar covers can heat your pool in the off-season, too. A pool cover reduces the pool’s chemical consumption and reduces your cleaning time.
How often should I need to add water to my pool?
Normally pools see ¼ – ½ inch loss of water per day due to evaporation. This is roughly 2 – 4 inches per week. For a normal sized pool you will loose 25,000 to 50,000 gallons of water per year due to evaporation. This means I was putting a hose in the pool every 7-10 days to fill the pool.
