Leaking swimming pools is the number one pool problem!

Most swimming pool repairs and pool renovations begin with an enquiry regarding a leak in the swimming pool.

No other pool problem concerns pool owners more than a water leak, this is because a leaking swimming pool consistently costs more to maintain due to the excess water usage reflecting on the consumer's water bill.

If you want to do a preliminary test yourself prior to hiring a leak detection specialist, you should read the following information.


Most common places for a pool to leak from.

In order from the most common to the least.

  1. Hydro-static Valve.
  2. Within the pool equipment system.
  3. Around the skimmer box. 
  4. Around pool returns. (Between the pipes & concrete)
  5. Within the solar heating system.
  6. In the pool shell. (Cracks and joints)
  7. Behind the pool lights.

How to test for a pool leak.

Note: Rain or an excessively hot day will affect the result of the tests.

Pool leak bucket test.
  • Fill the swimming pool to the appropriate level.
  • Fill a bucket with water almost all the way to the top.
  • Place the bucket on a secure platform within the pool, such as the first pool step.
  • Draw a mark on the outside of the bucket, marking the current level of water in the pool.
  • Wait 24 hours and check if the water level is below the mark drawn the previous day.
Pool leak ruler Test
  • The water of the pool should be at the required height level.
  • Use a wooden ruler with the lowest denomination downward.
  • Vertically place the ruler against the top of the first pool step. (Do not let go)
  • The pool water will naturally mark the ruler.
  • Write down the measurement of the water height.
  • 24 hours later, repeat this process.
  • Compare the two measurements to reveal if there was a drop in the water depth. 

Both tests should be done twice, once with the pool equipment switched off and once with the pool equipment on.


Pool leaks with pump on.

If the swimming pool is leaking only when the pump is on, usually it is a sign that the leak is located within the pool system.

But you must also be aware, if you have two pumps and one is the solar, test it separately.

Pool leaks with pump off.

When the pool equipment is switched off the leak is usually located within the pool shell.


How to find a Pool Leak?

The best way to find a pool leak is to hire a pool leak detection specialist.

Finding a pool leak without the right equipment is near impossible.

Hiring a professional is the most time efficient and secure way to guarantee locating and repairing a leak.

Dye for leak detection.

Dye for leak detection is available at most swimming pool stores.

If you have a suspicion of where the leak is located, while the pool or spa is filled with water you can squeeze out some of the dye near the suspect area and see if the dye is following through.

Finding one leak does not always solve the problem, the swimming pool can be leaking from multiple spots throughout, hiring a professional leak specialist is best practice.
