LEAK TECH, pool leak detection & repair specialists, can find and repair any leak.
If your pool has a broken pipe under the pool or around the pool area.


Pool leaks are a serious problem that all pool owners face. Leaks can create long term side effects including structural damage to the pool shell, damage to concrete, lawns and other surrounding areas.
Pools are meant to be watertight, but sealants will deteriorate and other parts of your pool shift and settle or just wear out. Pools can leak through any of the fittings or accessories, plumbing or even through the shell. It is important to repair leaks, not only to save water, heat and chemicals, but to prevent serious damage to the ground supporting the pool shell.

A concrete pool can actually rise and float out of the ground when it becomes empty because of the excess water adding to the water table.
The first challenge is to confirm whether your pool actually has a leak - or is the water loss due to other factors, such as excessive splashing or by natural evaporation.

*in 95% of cases.


. You may have a leak if:
  • The water level is dropping faster than normal
  • The pool has air in the system
  • There is a significant increase in you water bill
  • There are soggy spots around the pool
  • You add water more than once a week
  • The pool area is lifting
  • You see cracks appearing in and around the pool area
  • You are using more chemicals than normal
  • Your automatic pool filler is running more than normal

bucket test



There are many reasons Why pools leak including:

  • Your pool may have leaked from the day it was built
  • During construction a pipe fitting may not have been glued properly
  • Ground settling issues can cause plumbing to sag and break
  • A small leak in pipes can cause tree roots to migrate toward the moisture in the soil and the roots will wrap around pool plumbing and crack a pipe
  • Pool tile grout can crack below the normal water line, or the pool might just develop a crack
  • Any place where plastic pipe comes through the pool shell can Develop leaks as the pools interior finish begins to deteriorate
  • As weather changes your pool will expand and contract and generally making small leaks bigger leaks
  • Small leaks always create a larger problem eventually

The longer a leaking pipe, liner or pool shell is left unrepaired the more costly it can be to fix and become an unrepairable problem if ignored!!

The Bucket Test

A quick and easy way to determine if your pool is leaking or if it is evaporation is to perform a bucket test:

1. Fill a five gallon bucket to 3/4 full or to within three inches from the top.
2. Set the bucket on the second step of the pool if possible, making sure that the water level is higher on the inside of the bucket.
3. Turn off the pump and ensure water is still.
4. Make a mark on both the inside and outside of the bucket to indicate each water level leave in place for 24 hours.
5. Measure the change in water level for each mark.
6. If the difference on the outside (pool level) is greater than the inside (bucket level) you have a leak - please get in touch!
