Is it normal for pool water to evaporate?

However, more often than not, your pool water is just naturally evaporating into the air.

In fact, the average pool loses 1 ½ inches of pool water a week through evaporation..

How do you calculate the evaporation loss of a swimming pool?

Wavepools = 1.5+E = Evaporation Rate (Gallons/Day)A = Pool Surface Area (ft2)F = Activity Factor (See Table at Right)P = Water’s Vapor Pressure (mmHG) at Ambient Temperature.Pa = Water’s Vapor Pressure (mmHG) at Dew Point Temperature.

How often should you add water to your 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.

Does water evaporate at night?

Yes there is evaporation at night. … The rate of evaporation may slow down when it’s cooler, but it will happen. All you need is the right combination of temperature, pressure and humidity. As for the energy, the heat comes from the sun.

How high should the water level be in a swimming pool?

The level at which pool skimmers function properly is between one third and about half way up the opening of the pool skimmer. If the water level is too high the debris floating next to the opening may pass by without being pulled into the skimmer.

Does my pool have a leak or is it evaporation?

An easy way to determine if you have a pool leak or evaporation issues is to do a bucket test. Simply fill a 5 gallon bucket about 3 inches from the top of the bucket and place it next to the pool. With electrical tape or another easily removable tape mark the water line on the pool and the bucket.

Why is the water level in my pool dropping?

Natural causes such as wind, heat and humidity can contribute to pool water loss. This is a big deal, because if your water level gets too low it may cause your pool pump to suck air and run dry, which can damage it.

Can I shock my pool 2 days in a row?

It’s pretty tough to over-shock your pool; shocking your pool two days in a row with the proper dosage for your pool volume shouldn’t be a problem – and in fact, is sometimes even needed to rid your pool of algae and other contaminants.
