How do I know if my pool has a leak or it’s just evaporation?

Can a pool leak cause serious damage if left untreated?

Can you fix the leak once it’s found?

Common Signs of a Pool Leak

Water loss can sometimes be put down to evaporation, but not always. Here are a few common warning signs to keep an eye out for:


  • Water level falling faster than normal
  • Unusual gurgling or sucking noises
  • Dirt or air entering the pool through the return lines
  • Higher than usual power bills
  • Loose or cracked tiles around the pool edge
  • Algae growth or water that’s hard to balance
  • Standing water near or under pool equipment


If you notice any of these signs, contact Leaks Downunder for professional help identifying and fixing the issue.
