Why I Should Avoid  To Empty A Swimming Pool

Not only are pools looking neglected, they're also getting worse. This winter's wet weather has turned their water into a murky grey, and mould and mildew are starting to appear.

While the thought of draining your pool and starting over again might seem attractive, the consequences could mean more than an expensive water bill.

Draining or emptying your pool of water can create a number of financial and structural headaches, including:

  • Cracking the pool's shell
  • Damaging the interior lining or surface
  • Damaging the pool's coping and surrounding paving or timber work
  • Causing it to "float" due to hydrostatic pressure
  • Damaging expensive in-floor cleaning systems
  • Damaging pool lights
  • Causing a safety hazard for people, pets and local wildlife
  • Hefty fees if you're on a water metre


Regardless of what type of pool you own (above- or in-ground, or fiberglass), the chances of it incurring some sort of damage once it is emptied of water are likely. For example:

  • Above-ground vinyl liner – once drained, the liner can shrink and possibly tear when it's time to re-fill the pool, especially if it is an older liner
  • In-ground concrete – These types of pool structures are usually built to withstand the weight of the soil around them, but high ground levels can push them out of their foundations.
  • Fiberglass - This type of pool is easily floated when empty. It's similar to a fiberglass boat, which means that it can be positioned before being emptied of water.



These hydrostatic valves are located at the bottom of the pool and act as a natural filter, allowing the groundwater to seep in of the pool once it's empty.

While it's tempting to empty and re-water your pool, there are other ways to get it back into shape. One of these is by taking a water sample to a local swimming store.

If you go to a local pool store, they will be able to provide you with the information you need to bring your water back to its original balance.
