How can I tell if my pool is leaking or if the water loss is just normal evaporation?

Try the “Bucket Test” to determine if your pool is leaking or if it is just evaporation.

A: Bucket Test Steps:

• Bring pool water to normal operating level, typically halfway up the skimmer opening, and turn pool equipment off.

• Fill a bucket or large pail with pool water and place the bucket on the top step or sun shelf of your pool. The water level in the bucket should be 2-3” from the top of the bucket.

• Mark the water level inside the bucket, using a Sharpie, piece of tape, wax pencil, etc. This will be the evaporation test.

• Mark the pool water level on the outside of the bucket. This will be the pool leak test.

• Compare both levels after 24 hours.

• If the outside mark is greater than the inside mark, you have a leak.

What is allowable for evaporation?

Unfortunately there is no magic number or standard formula. There are many different variables in play that determine evaporation rates.


• Environmental conditions (i.e. Wind)
• Water features (Spa spillway, Sheer Descents, Fan Jets, etc.)
• Heating features (Heater, Heat Pump, Solar Panels)
• Screen enclosure
• Pool Interior finish
• Tile selection (Amount of grout being used)
• Rocks used for water features or as tile coping

Evaporation can range from 1/8” to 1/4”in. per day depending on the variables mentioned above.

Lately I’ve had to add a lot more salt to my saltwater pool than usual. Why?

This can be an indication of a leak, as the constant water loss can cause your pool’s salt content to quickly go out of balance.

We have air bubbles coming into the pool. Is this a problem?

We receive a lot of phone calls asking the same question. Air bubbles can be caused by problems with your equipment, such as cracked gaskets around the suction side of your pump. However, if you have determined your equipment is all in good repair, it’s possible you’re pulling air in from a broken pipe underground. If you have to add water frequently, then your pool is leaking.

I have algae growing in my pool, although I keep adding chlorine. What’s going on?

This can be an indication of a leak, as the constant water loss can cause your pool chemicals to quickly go out of balance. It can also be an indication you’re simply not using the right mix and amount of pool chemicals.

What is the best way to detect a leak under a concrete deck?

The lines must be pressure tested, and then a special listening device is used to locate the area of the leak. The Leak Wizard has the knowledge and specialized equipment to do this safely and accurately.
